Database - Built-in Checks

Here you will find detailed information about Built-in checks for Database monitored objects.

Built-in checks are deployed automatically for a monitored object type. Once Avantra has detected a specific monitored object, each of the relevant built-in checks will be auto-deployed to the agent to begin check execution and status reporting. Built-in checks can be configured using Monitoring Parameters (e.g. to set threshold values) and can also be disabled if they are not relevant to your landscape.

ADA_BACKUP

Checks the end date / time of the most recent backup required for complete recovery of the Database.

If it's older than a configured period of time, a Warning or a Critical message is generated.

The maximum allowed age can be defined generally by using parameters BackupAgeCrit and BackupAgeWarn and the corresponding Monitoring Exception Parameters.

Additionally, the check displays an overview of all backups required for the most recent complete Database recovery.

ANY_Backup

Checks for backup maintenance plans and verifies if they were successfully executed.

If no backup maintenance plan for full backup is found, the check status will be Critical and there will be no further check evaluation.

If there is a full backup maintenance plan, the reports of this plan will be evaluated. ANY_Backup collector will select reports of the last ANYBackupSelectRange days. For the backup check to be Ok, a successful report must be found, and the finished time of the last full backup must be below thresholds ANYBackupFullWarnAge and ANYBackupFullCritAge.

Additionally, the age of the last successful backup must be below BackupAgeWarn and BackupAgeCrit, but it's not required that the last successful backup is a full backup. If the latest backup was unsuccessful, the check status will be Warning unless Critical thresholds are exceeded.

Monitoring Parameters	ANYDBUsageCrit, ANYDBUsageWarn, ANYDBForecast, ANYDBExCrit, and ANYDBExWarn

ANY_Messages

The check queries for server messages within the last day. If Monitoring Parameter RunDailyCheckOnWE is false, the check queries for server messages for the last 3 days on Mondays, to make sure you do not miss any entries.

The check status is Ok if only INFO messages are found or the number of ERR and WARN messages is below ANYMessagesNumWarn. If the number of both, ERR and WARN messages is above ANYMessagesNumWarn the check status is Warning, unless the number of ERR messages is exceeding ANYMessagesNumCrit which will result in Critical check status.

note

If only INFO messages are found, the latest 100 INFO messages will be displayed. If ERR or WARN messages are found, INFO messages will not be displayed. The maximum number of ERR or WARN messages displayed is limited to a total number of 500 messages.

It is possible to exclude messages from being counted as WARN or ERR messages. To do so, please use Monitoring Parameter ANYMessagesExclude, see the parameterÊ¼s documentation for the syntax details.

DB2_BACKUP

Checks the last full database backup and shows its start, end and runtime.

If it was not successful a Warning or Critical status is reported, depending on the exit state of the latest backup command.

Additionally, the age of the last successful backup is checked. If the last successful backup is too old a Warning is reported. The maximum age can be defined using BackupAgeCrit and BackupAgeWarn. There is also the option to define a Monitoring Parameter Exception.

note

The backup granularity (i.e. tablespace or database) is not considered. Tablespace backups are therefore considered in the same way as full database backups. If you use tablespace backups, you need to take care of an appropriate backup strategy. However, the granularity is displayed with the Check Result for your information.

Monitoring Parameters	BackupAgeWarn, and BackupAgeCrit

DB2_BACKUPSTAT

The return code of the latest backup is evaluated.

If the return code is 0, the check status will be OK, in case the value is 1, the status will be Warning. Otherwise, the status is set to Critical.

This check reports to the RealTime Monitoring. BackupResetRTMTime can be used to reset the check status back to OK automatically after a certain period of time.

DB2_CBO_STATS

Counts the number of tables/indexes with statistics not older than DB2CBOMaxAge days.

If the number of tables/indexes with up-to-date statistics is below threshold DB2CBONumEntriesUpdCrit or DB2CBONumEntriesUpdWarn the check will return a Critical or a Warning message.

ABAPDBSchema is used if you need to override the schema name for this check.

Monitoring Parameters	DB2CBONumEntriesUpdCrit, DB2CBONumEntriesUpdWarn, and DB2CBOMaxAge

DB2_DIAGLOG

An alert is raised if a certain number of entries with a Warning, Error, or Severe value in the Level property are found during a configurable period of time.

DB2_DIAGLOG can be configured in a very flexible way. The log parsing engine allows you to access any field of a DB2 diagnostics log entry, and you have the option to define virtually any Boolean expression in order to consider certain entries as Warning or Critical.

The check evaluation rule is: If there are more than DB2DiagLogCountCrit entries found during the past DB2DiagLogTimeSpan minutes matching the expression DB2DiagLogExprCrit, the check status will be Critical. Otherwise, if there are more than DB2DiagLogCountWarn entries during the same time span matching the expression DB2DiagLogExprWarn, the check status will be Warning. Otherwise, it will be OK.

The location of the DB2 diagnostics log file is determined by the diagpath DB2 Database parameter. In case diagpath is not set, the check returns a Warning.

DB2_DIAGLOG is not supported for systems using a remote database (i.e. if DB2DBRemote is set to 1)!

DB2_ExpSQL

Reports expensive SQL statements considering the I/O of all statements in query cache.

An SQL statement is considered expensive if the amount of logical and/or physical reads for the particular statement exceeds a certain amount of all logical and physical reads.

Warning and Critical thresholds can be defined for the logical and physical reads, and statements can be excluded from the check.

Monitoring Parameters	DB2ExpSQLPhysicalReadWarn, DB2ExpSQLPhysicalReadCrit, DB2ExpSQLLogicalReadWarn, DB2ExpSQLLogicalReadCrit, DB2ExpSQLExclude, and DB2ExpSQLExcludeShow

DB2_FSLOGARCH

The check execution depends on the configuration of your DB2 UDB Database.

The usage of the filesystem holding the active transaction log directory (as defined in the DB2 parameter logpath) is monitored using DB2FSLogActiveCrit and DB2FSLogActiveWarn. Forecasting is enabled as well, and configured using DB2FSLogArchExCrit, DB2FSLogArchExWarn, and DB2FSLogArchForecast.
Additionally, the filesystem holding the directory mirrorlogpath (if defined) will be checked as well.
The Avantra Agent will figure out the DB2 log management method in place by examining the DB2 parameters logarchmeth1 and userexit.
If the database is running in log retention mode (also called archive logging mode) and it's configured to archive transaction log files to disk, the file systems holding the archived transaction log files are monitored using the following monitoring parameters: DB2FSLogArchWarn, DB2FSLogArchCrit, DB2FSLogArchExWarn, DB2FSLogArchExCrit, and DB2FSLogArchForecast.
If the DB2 parameter failarchpath is set, the Avantra Agent will verify if transaction log files have been archived to this location.
Such a situation occurs in case your DB2 UDB Database was not able to archive to the primary and the secondary (if set) archive destinations, for instance, if destinations like TSM or VENDOR are used. The existence of files in failarchpath indicates a serious issue. Therefore the Avantra Agent will not monitor the amount of used space on the corresponding file system, but only count the number of transaction log files found. It raises an alert if either DB2NumFailArchLogsWarn or DB2NumFailArchLogsCrit thresholds are exceeded.

The DB2_FSLOGARCH check is not supported for systems using a remote database (e.g. DB2DBRemote is set to 1).

DB2_LOGUSAGE

An alert is raised if the log space of the DB2 UDB Database exceeds some configurable threshold, or if the predicted log space exhaustion is within a configurable period of time.

Check Cycle	Basic
Depends on	DBCONNECT
Monitoring Parameters	DB2LogForecast, DB2LogExCrit, DB2LogExWarn, DB2LogUsageCrit, and DB2LogUsageWarn

DB2_TABLESPACES

An alert is raised if tablespace usage exceeds some configurable threshold, or if the predicted tablespace exhaustion is within a configurable period of time. Exceptions to the general Warning and Critical thresholds may be defined on a per tablespace level.

Auto-resize tablespaces are supported as well. The check considers the space available assuming that the tablespace can be resized to its limit regardless of any underlying file system limitations. If a tablespace is configured with the "unlimited" maximum size (i.e. tablespace_max_size is -1), the architectural size limit of the tablespace is considered (see also DB2 Linux, UNIX and Windows (LUW) SQL and XML Limits).

You can distinguish auto-resized tablespaces from other ones in the Check Result. If a tablespace is configured using auto-resize, you will get the following result in case of a Warning or Critical check status:

'PSAPBTABD' is used by 96.6 % (17.51 GB free, 17.51 GB auto-resize free)

Since — in the example above — the amount of actual free space in the tablespace is identical to the maximum available auto-resize free space the tablespace will not extend any further and it might be time to reorganize or to upgrade to large tablespaces.

The following example shows the situation where a tablespace still can be auto-resized:

'PA3#ODSI' is used by 9.7 % (25.61 GB free, 231.27 GB auto-resize free)

note

The Avantra Agent does not check if there is enough space on the filesystem to actually resize a tablespace. You need to monitor the file systems as well using FILESYSTEMS.

Managed System	DB2 Database
Check Cycle	Basic
Depends on	DBCONNECT
Monitoring Parameters	DB2TableSpaceUsageCrit, DB2TableSpaceUsageWarn, DB2TableSpaceForecast, DB2TableSpaceExCrit, and DB2TableSpaceExWarn

DBCONNECT

Verifies the connection to a Database. If the Database connection has been established successfully, the check will provide some additional information in its result.

If the Database connection fails, the Check Result will be Warning and after DBConnectErrsCrit subsequent connection attempts without success, the result will be Critical.

Additionally, the check serves as a overview check for all other checks executed on a Database, so if the connection fails, all the other dependent checks will return Unknown.

The DBCONNECT check therefore is the most important check for a Database.

note

SAP Systems with Oracle Database only: The Avantra Agent by default tries to connect the Oracle database using TNS lookup with the SAP System's Real SAP SID as TNS alias.

If this fails (for example because the TNS admin directory could not be determined) you can make use of the Parameter Set ORATNSAdminDir and ORATNSAlias.

note

Oracle Databases in conjunction with SAP BR*Tools only: If there is a running off-line backup, the check will return a Warning. If the elapsed time (since backup start) is ORABrbackupOfflineDelayCrit percent longer than the average total backup runtime of the last 5 full backups, a Critical alert is raised. If there are less than 2 full backups available a backup time of 4 hours is assumed.

FULLCHECK

Returns the overall status of all Checks executed during the Daily Check on a particular SAP Instance or Database.

For instance, if the connection attempt (to the SAP Instance or Database) failed, this check type returns a Critical message. If this check fails, all other dependent checks will have status Unknown.

In the OK status, the check explains what checks were executed for a particular SAP Instance or Database, which profiles were collected, etc.

Monitoring Parameters	HDBAdmissionTimeSpan, HDBAdmissionMaxRows, and HDBAdmissionStatus

HDB_Alerts

Monitors the alerts generated by the statistics server. The alerts are counted according to their priority: Error, High, Medium, and Low.

The check status is set to Warning if at least one alert with priority Error or High is found within the timespan defined by HDBAlertsTimeSpan. If the number of Error alerts is above HDBAlertsErrorCountCrit or the number of High alerts is above HDBAlertsHighCountCrit the check status is set to Critical.

note

Since the default values for HDBAlertsErrorCountCrit and HDBAlertsHighCountCrit are both configured to 1, by default the check status is Critical starting from one Error or High alert.

The check turns to Warning if the number of alerts with rating Medium found within the timespan defined by HDBAlertsTimeSpan is equal to or above HDBAlertsMediumCountWarn, or if the number of alerts with rating Low found within the timespan defined by HDBAlertsTimeSpan is equal to or above HDBAlertsLowCountWarn.

The status for HDB_Alerts will be OK if no alerts with priority above Medium are found, and the number of Medium priority alerts is below the HDBAlertsMediumCountWarn threshold and the number of Low priority alerts is below the HDBAlertsLowCountWarn threshold.

Finally, you can exclude alerts from contributing to the check status by specifying the alert's ID using parameter HDBAlertsExcludeIDs. Multiple entries must be separated by spaces, comma, or semicolon. HDBAlertsExcludeIDs' syntax is forgiving, i. e. leading, trailing or multiple spaces will not harm and the right alerts will still be excluded as long as numeric values are found.

note

Excluded alerts will still be reported in the check result's overview table. They will be marked with string (Excluded) in the Alert ID column and will not be colored.

HDB_LicenseCompliance

Verifies whether the SAP HANA database is being used in compliance when the license type is a Runtime License, such as a license that is used only for backing SAP applications and not to be used as a regular database by third party or custom applications.

The check will have a Warning status if Avantra is unable to determine the license type of the SAP HANA database. This will be due to the HANA parameter license_type not being set. See SAP Note 2779499 - SAP HANA Runtime License for more information.

The check will have a Critical status if the license type is a Runtime License and the monitoring user has excess roles compared to the baseline monitoring user for Avantra.

ORA_ALERTLOG

Verifies the Oracle alert log file.

A Critical alert is raised if a certain number of the following entries is found during a configurable period of time:

Oracle Database Error Messages: ORA-00255, ORA-00257, ORA-00270, ORA-00272, ORA-00376, ORA-00447, ORA-00470, ORA-00471, ORA-00472, ORA-00473, ORA-00474, ORA-00600, ORA-00603, ORA-01113, ORA-01114, ORA-01115, ORA-01122, ORA-01135, ORA-01578, ORA-01628, ORA-01629, ORA-01630, ORA-01631, ORA-01632, ORA-01650, ORA-01651, ORA-01652, ORA-01653, ORA-01654, ORA-01655, ORA-01656, ORA-01680, ORA-01681, ORA-01683, ORA-01684, ORA-01685, ORA-01688, ORA-01691, ORA-01692, ORA-01693, ORA-01694, ORA-03113, ORA-07445, ORA-16014, ORA-16038, ORA-19502, ORA-19504, ORA-19510, ORA-27044, ORA-27063, ORA-27072, ORA-30036.
Messages containing Corrupt block.

A Warning alert is raised if a certain number of the following entries is found:

Oracle Database Error Messages: ORA-00060, ORA-01149, ORA-01555, ORA-01562.
Messages containing Checkpoint not complete.

ORA_ALERTLOG can be configured in a very flexible way. The log parsing engine allows you to access any field of an Oracle alert log entry, and you have the option to define virtually any Boolean expression in order to flag certain entries as Warning or Critical.

The check evaluation rule is: If there are more than ORAAlertLogCountCrit entries found during the past ORAAlertLogTimeSpan minutes matching the expression ORAAlertLogExprCrit, the check status will be Critical. Otherwise, if there are more than ORAAlertLogCountWarn entries during the same time span matching the expression ORAAlertLogExprWarn, the check status will be Warning. Otherwise, it will be OK.

The location of the Oracle alert log file is determined by ORAAlertLogLocation. If this parameter is not set, the value from the DIAGNOSTIC_DEST (for Oracle 11g and newer) or BACKGROUND_DUMP_DEST (Oracle 10g and older) parameter is considered.

A Warning Check Result will be returned if the location cannot be determined.

ORA_BACKUP

This check verifies the availability and consistency of the latest backup performed with the Oracle Recovery Manager (RMAN).

The check is only executed if parameter ORABackupTool is set to RMAN which is the default for standalone Databases.

If your database is backed up with SAP BR*Tools, you should set ORABackupTool to BRBACKUP (default for SAP System). In this case, this check is automatically deleted.

If you neither use RMAN nor the BR*Tools to backup your Oracle Database you are encouraged to disable this check.

Basically, a backup is considered available and consistent if it can be recovered byRMAN. So the check verifies if the control file, spfile, datafiles, and archive log files backups are consistent and if the point in time they can be recovered to is not older than thresholds defined in BackupAgeWarn or BackupAgeCrit. Otherwise, the check will report a corresponding Warning or Critical Check Result.

The consistency check of the backups comprises the verification of consistent SCN (System Change Numbers, Transaction Numbers) chains contained in valid incremental backups starting with a valid full backup.

The latest SCN of the newest complete incremental backup chains of the datafiles are searched for in the Redo Log Backup Sets, and starting from the oldest set, the Redo Log Backup SCNs are checked for consistency up to the last entry.

For further information on Backup Sets and SCNs, see the oracleRMANDoc.

If backups are written to disk, the check also verifies if the files are available on disk, unless ORABackupSkipFilesCheck is set, or the database is monitored remotely (indicated by ORADBRemote). The Avantra Agent needs the appropriate permissions on the file system to verify the existence of the files. Set the ORABackupSkipFilesCheck otherwise.

The check will return Critical also if no backup is found within the period defined by ORARMANSelectRange.

note

If you manipulate files already backed up (e.g. remove or rename them) using other tools thanRMAN,RMANmay not know about these changes. Neither does the Avantra Agent. You should run a crosscheck within RMANin this case.

note

The check is always related to the latest backup. It does not check if your Database can be restored using any backup before the latest one. It does, however, check if the redo logs required to restore the latest backup are all backed up, too.

ORA_BRBACKUP

This check type comprises two different sub-checks:

The return code of the latest backup is evaluated. If the return code is 0, the check status will be Ok, in case the value is 1, the status will be Warning. Otherwise, the status is set to Critical.
If the latest successful backup (i.e. one with a return code 0 or 1) is older than a configured period of time, a Warning or Critical message is generated.

The check is only executed if ORABackupTool is set to BRBACKUP, which is the default for an SAP System. If your database is not backed up with SAP BR*Tools, but with RMAN, you should set ORABackupTool to RMAN (default for standalone Databases). In this case, this check is automatically deleted.

ORA_BRBACKUPSTAT

This check type comprises two different sub-checks:

The return code of the latest backup is evaluated. If the return code is 0, the check status will be OK, in case the value is 1, the status will be Warning. Otherwise, the status is set to Critical.
The runtime of the backup is verified. The runtime is compared with the average runtime of the previous 2 to 5 (if available) backups, and additionally it's compared against a static time threshold. This shall help to reduce false alerts especially if average backup times are small. If the current runtime takes more than ORABrbackupDelayWarn percent longer than the average and is above ORABrbackupDelayTimeWarn minutes, the check status is set to Warning. If it takes more than ORABrbackupDelayCrit percent longer and is above ORABrbackupDelayTimeCrit minutes, the check status is set to Critical.
If we cannot compute an average, a value of 4 hours is assumed.

note

If you neither use RMAN nor the BR*Tools to backup your Oracle Database, it's recommended to disable this check.

This check reports to the RealTime Monitoring. BackupResetRTMTime can be used to reset the check status back to OK automatically after a certain period of time.

ORA_DATAFILES

This check comprises two sub-checks:

The status of each datafile is checked and a Critical alert is raised unless it's either ONLINE or SYSTEM.
The check calculates how many auto extent increments will fit into the filesystem where the datafile is located.

If the number of increments is below ORADataFileIncrementsCrit, a Critical alert is reported, if it's below ORADataFileIncrementsWarn but not below ORADataFileIncrementsCrit, a Warning is raised.

ORA_DBAOPER

This check verifies certain Oracle DBA operations that are executed with BR*Tools.

The operations can be selected by defining their Function IDs (e.g. as listed in transaction DB14) in ORADBAOperFunctionIDs.

The check is only executed if ORASAPToolsEnable is set to 1, which is the default for SAP Systems. For standalone Databases, this check is by default disabled (ORASAPToolsEnable is set to 0). If you enable the check, defining ORASAPToolsSchema may be required.

The check consists of two sub-checks:

The return code of the latest finished DBA operation is checked. If the return code is 0, the check status will be OK If it's 1, the check status will be Warning, otherwise, the check status will be Critical. Running operations with RC=9999 are ignored.
It is verified if the latest successful DBA operation is not older than defined in the ORADBAOperAgeCrit or ORADBAOperAgeWarn thresholds. Otherwise, the check status will be set accordingly.

By default, the following operations are checked:

Collect Optimizer Statistics
Database verification with DBVERIFY
Check Optimizer Statistics.

ORA_DBCHECKLOG

The result of the latest sapdba -check or brconnect -f check run is parsed. If the last run is older than 24 hours, a Warning message is raised. Data is only searched for in the time span defined by ORABrToolsSelectRange.

Otherwise, the result is not too old. It is analyzed as follows: if the result contains messages with W level, the check returns a Warning, if the result contains messages with E level, the check returns Critical.

ORA_Enqueue

This check collects enqueue statistics on timeouts, waits, and deadlocks. The statistics are temporarily stored with a timestamp. The check then verifies if the statistics values exceed one of the defined thresholds in a certain time span.

For deadlocks, absolute numbers are collected and verified. As Oracle recommends examining each deadlock, the default Critical threshold for deadlocks is set to 1.

Timeouts and waits are calculated as a ratio to the total number of enqueue requests and conversions. This allows the check to scale on huge Databases, where more enqueue requests will occur, resulting in more timeouts and wait events.

All thresholds can be configured by means of Monitoring Parameters. For each statistics value there are two separate thresholds for Warning and Critical check status available. By default, the Warning thresholds are disabled, i.e. they have the same default value as their corresponding Critical threshold. The threshold parameters are: ORAEnqueueDeadLocksCrit/ORAEnqueueDeadLocksWarn, ORAEnqueueTimeoutsCrit/ORAEnqueueTimeoutsWarn, ORAEnqueueWaitsCrit/ORAEnqueueWaitsWarn.

By setting a Critical threshold to 0 (or < 0), the associated statistics check is turned off for example, setting ORAEnqueueTimeoutsCrit to 0 disables the timeouts part of the check.

The time span by which the statistics are collected and verified can be configured using the ORAEnqueueTimeSpan.

ORA_SEGMENTS

The check analyzes the Oracle segments (e.g. tables and indexes) of tablespaces with dictionary extent management and permanent storage in two ways:

If the number of allocated extents exceeds a configurable threshold of the segment's maximum number of extents (as defined by the table or index storage parameter max_extents or Critical alert is issued.
A Critical alert is issued if the continuous space in a tablespace is not large enough to allocate another extent (known as table or index storage parameter next_extent) for a segment.

For databases with locally managed tablespaces only, the Check Result simply displays a message

Database does not contain tablespaces with dictionary extent management and permanent content.

If the check status is OK, and if the database contains dictionary extent management tablespaces, the check will display the covered tablespaces:

Segments are checked in tablespaces with dictionary extent management and permanent content: PSAPC11DB, SYSTEM
All segments can allocate another extent.
All segments' number of extents are below threshold.

Due to resource consumption, this check is by default configured to run only every 60 minutes (see ORASegsChkWaitTime) in RealTime Monitoring. This check also runs in the Daily Check.

ORA_Sessions

This Check counts the number of waiting sessions, considering wait time, wait class, and wait status of each session.

For each session waiting and holding a matching wait class (at time of Check execution), the wait time is compared against a Warning and a Critical wait time threshold (Monitoring Parameters ORASessionsTimeWaitWarn and ORASessionsTimeWaitCrit). All Warning and Critical sessions are counted, and the counter is compared against a count threshold (Monitoring Parameter ORASessionsCountWait). If the count threshold is exceeded by the Critical sessions, the check will be Critical, otherwise, if the count threshold is exceeded by the Critical and Warning sessions, the check will be Warning.

The wait class of a session is considered to filter out sessions not accounting for the check status. The wait class filter can be configured by means of the ORASessionsIgnoreWaitClass Monitoring Parameter.

ORA_TABLESPACES

An alert is raised if the tablespace usage exceeds some configurable threshold, or if the predicted tablespace exhaustion is within a configurable period of time.

Exceptions to the general Warning and Critical thresholds may be defined on a per tablespace level.

For tablespaces with auto-extent enabled, the maximum allocatable space (in the check message labeled auto-extent free) is considered as free space for usage and remaining free space calculations, and not the real free space (labeled free) considering the currently allocated tablespace size.

warning

The value of auto-extent free is not limited by the effective free space of the filesystems holding the tablespace's datafiles. The ORA_DATAFILES check, however, verifies if auto-extensible datafiles can be extended within their filesystems.

The details about exhausted tables are only shown when:

Forecasting is enabled for the system (use ORATableSpaceForecast monitoring parameter)
The tablespace is growing
The currently used tablespace is more than 50%
The value in 'Exhausted In' column is less than one year

The check complements the SYB_Backup with a RealTime Monitoring check, which immediately displays a Warning or Critical status when the last backup has failed. The status displayed after a backup has failed can be configured with monitoring parameter SYBBackupStatFailedStatus. SYBBackupStatFailedDisplayTime minutes after the failed backup has been detected, the check result status is reset to OK.

If a backup is currently being processed, the check verifies the current runtime since the backup start and compares it against the average backup time of the last 5 successful backups, and additionally, it's compared against a static time threshold. This shall help to reduce false alerts especially if average backup times are small. If the current runtime takes more than 50 percent longer than the average and is above SYBBackupStatDelayTimeWarn minutes the check status is set to Warning. If it takes more than 100 percent longer and is above SYBBackupStatDelayTimeCrit minutes the check status is set to Critical.

If no 5 successful backups are found the check takes the average runtime of as many backups as possible. If none is found at all, the average runtime is initialized to 2 hours.

More importantly, the check verifies if suspect pages are reported for a database. If yes, the check status will be Critical. If a database is marked as suspect, you should find the reason for this. Usually, there are entries in the error log. Please refer to Sybase/SAP documentation on how to proceed and how to reset the suspect status.

The check table includes much information for your reference and overview. The same data is checked elsewhere, e.g. in checks SYB_DataSpaces and SYB_LogSpaces.

Reference Data


Managed System	SAP ASE Database
Check Cycle	(../../Glossary/#check-cycle)
Depends on	DBCONNECT
Monitoring Parameters	None

SYB_DataSpaces

The check verifies if enough data space is available in all databases. If the usage or the amount of remaining free space is exceeding/falling below SYBDBUsageCrit, the check status will be Critical. If the usage or the amount of remaining free space is exceeding/falling below SYBDBUsageWarn but is still below/above SYBDBUsageCrit, the status will be Warning.

The total check status is the worst of all sub-status of all databases. You can see the sub-result for each database in the table provided. This check features Monitoring Parameter Exceptions so you may define individual thresholds for certain databases.

Monitoring Parameters	SYBDBUsageCrit, SYBDBUsageWarn, SYBDBForecast, SYBDBExCrit, and SYBDBExWarn

SYB_ErrorLog

The check queries the Sybase error log for entries within the last day. If Monitoring Parameter RunDailyCheckOnWE is false, the check queries the error log for the last 2 days on Sundays, and for the last 3 days on Mondays, to make sure you do not miss any entries.

The check status is OK if no entries at all or only entries with severity level 0 or 10 are found. If any entries with severity level ≥11 and ≤16 are found, the check status is Warning. If entries with severity level 17 or above are found, the check result will be Critical.

Severity level 17 means Insufficient Resources, for example, space allocation fails due to missing free extents in a data segment.

Severity level 21 and above means, that SAP ASE needs to be restarted or is damaged and must be repaired.

Please check the SAP Sybase ASE guide System Administration Guide: Volume 1 for information on severity levels and how to proceed in case you encounter severe error log entries.

Monitoring Parameter SYBErrorLogExcludeErrNums may be used to exclude certain error numbers from being checked. Enter a comma or blank-separated list of numbers to specify multiple values.

Check Cycle	Full
Depends on	None
Monitoring Parameters	SYBErrorLogExcludeErrNums, and RunDailyCheckOnWE

SYB_ErrorLogStat

SYB_ErrorLogStat does the same as SYB_ErrorLog — monitoring the ASE error log, but queries it for entries within last SYBErrorLogTimeSpan minutes only and reports to RealTime Monitoring.

Reference Data


Managed System	SAP ASE Database
Check Cycle	(../../Glossary/#check-cycle)
Depends on	DBCONNECT
Monitoring Parameters	SYBErrorLogTimeSpan, and SYBErrorLogExcludeErrNums

SYB_LogBackup

This check monitors if the last transaction log backup is recent enough. This is important to ensure the recoverability of your databases.

If the last transaction log dump is above SYBLogBackupAgeWarn minutes ago, but below SYBLogBackupAgeCrit minutes, the check status is Warning. If the last transaction log dump is above SYBLogBackupAgeCrit minutes ago, the check result is Critical. If a database reports a full transaction log, the check result is reported Critical. Please note that a full transaction log should usually not happen, since exhausting log space should be reported in advance by the SYB_LogSpaces check.

You may exclude databases from being checked by adding the name of the database to the comma-separated list defined by SYBLogBackupExclude. Many system databases are already excluded by default. However, databases are still checked for the full transaction log, no matter if excluded or not.

Check Cycle	(../../Glossary/#check-cycle)
Depends on	DBCONNECT
Monitoring Parameters	SYBLogBackupExclude, SYBLogBackupAgeCrit, and SYBLogBackupAgeWarn

SYB_LogSpaces

This check corresponds to the SYB_DataSpaces check but verifies if enough log space is available in all databases. If the usage or the amount of remaining free space is exceeding/falling below SYBLogUsageCrit, the check status will be Critical. If the usage or the amount of remaining free space is exceeding/falling below SYBLogUsageWarn but is still below/above SYBLogUsageCrit, the status will be Warning.

The total check status is the worst of all sub-status of all databases. You can see the sub-result for each database in the table provided. In contrast to SYB_DataSpaces, this check does not feature Monitoring Parameter Exception.
