SAP Instance - Monitoring Parameters

AutoChangeDetectionIgnore is used to exclude parameters from System Change Auto Detection. If, for example, a parameter value changes regularly and this behavior is well known, you may add the parameter to the exclude list.

The parameter value is still updated in the Avantra Database, but no change record will be created. Since there are several change detection objects, you must prefix the list with a keyword to indicate the object type.

For SAP Instances, INSTPROFPARAM, J2EESYSPROP, and J2EEVMPARAM are currently supported. Wildcard * is supported to define multiple parameters.

If the current number of entries in one of the dispatcher queues exceeds DispatcherQueueFillRatioCrit times the number of available work processes, the DispatcherQueue Check turns to Critical.

If the current number of entries in one of the dispatcher queues exceeds DispatcherQueueFillRatioWarn times the number of available work processes, the DispatcherQueue Check turns to Warning (unless one of the critical thresholds is exceeded).

If the current number of entries in one of the dispatcher queues compared to the maximum number of queue entries exceeds this threshold, the DispatcherQueue Check turns to Critical.

If the current number of entries in one of the dispatcher queues compared to the maximum number of queue entries exceeds this threshold, the DispatcherQueue Check turns to Warning (unless one of the critical thresholds is exceeded).

Starting from ERSConnectErrsCrit failed connection attempts the check status will turn from Warning to Critical.

If the ratio of current connections to the maximum available connections exceeds ICMConnUsageCrit percent, the check status turns to Critical.

If the ratio of current connections to the maximum available connections exceeds ICMConnUsageWarn percent, but not ICMConnUsageCrit percent, and none of the thresholds ICMQueueUsageCrit or ICMThreadsUsageCrit is exceeded, the check status turns to Warning.

If the ratio of current queues to maximum available queues exceeds ICMQueueUsageCrit percent, the check status turns to Critical.

If the ratio of current queues to maximum available queues ICMQueueUsageWarn percent, but not ICMQueueUsageCrit percent, and none of the thresholds ICMConnUsageCrit or ICMThreadsUsageCrit is exceeded, the check status turns to Warning.

If the ratio of current created worker threads to maximum available worker threads exceeds ICMThreadsUsageCrit percent, the check status turns to Critical.

If the ratio of current created worker threads to maximum available worker threads exceeds ICMThreadsUsageWarn percent, but not ICMThreadsUsageCrit percent, and none of the thresholds ICMConnUsageCrit or ICMQueueUsageCrit is exceeded, the check status turns to Warning.

In case the SAP Instance Auto Discovery finds a double-stack instance but the Java part is not used intentionally you can use this parameter to prevent the Java add-in from being monitored.

To suppress monitoring of the integrated Web Dispatcher on an Abap_Scs with Web Dispatcher instance, you may set this parameter to true. The Abap_Scs with Web Dispatcher instance will then be regarded as an ordinary Abap_Scs instance, and all checks and performance values related to Web Dispatcher monitoring won’t be available.

If the downtime of a properly shut down SAP Instances exceeds InstanceDowntimeCrit minutes the RFCConnect, J2EECONNECT, or SCS_MSGSRV check status turn from Warning to Critical.

If the number of used application threads exceeds J2EEApplThreadsPoolUsageCrit percent of the maximum thread pool size, the check status is set to Critical.

If the number of used application threads exceeds this value but does not exceed J2EEApplThreadsPoolUsageCrit percent of the maximum thread pool size, the check status is set to Warning.

Starting from J2EEConnectErrsCrit consecutive failed connection attempts the check status will turn from Warning to Critical.

Starting from J2EEConnectHttpErrsCrit consecutive failed HTTP connection attempts the on the system info page check status will turn from Warning to Critical.

The parameter can be used to configure custom keywords, which serve to verify the validity of the /nwa/sysinfo page, which is retrieved by the J2EEConnectHttp check. If one of the keywords is found on the page, the page is considered to be valid and the J2EEConnectHttp check is OK.

By default, the check J2EEConnectHttpPageKeywords looks for the instance host name on the page. For customised pages, which do not contain the instance host name, this turns the check to Critical.

If you specifiy a '*', the page verification is omitted, and a successful login to any page is accepted.

Defines the URL to be used by the J2EEConnectHttp Check.

The following syntax is supported:

In the #http/https[] options, placeholders for hosts and ports can be used. Specify <host> to let the Avantra Agent use the default host (usually 'localhost') and/or <port> to let it use the default port of the specified protocol (5<sysno>00 for http and 5<sysno>01 for https).

You can also use client authentication in conjunction with https. See the description of the J2EEKeystoreName Monitoring Parameter for further information.

This password is used to retrieve the keys from the keystore specified in the J2EEKeystoreName Monitoring Parameter. Do not define this parameter unless the keystore keys are password protected. See the description of the J2EEKeystoreName Monitoring Parameter.

If you use the J2EECONNECT check with https, you might also want to use certificates to authenticate the server and client. Whereas server certificates are handled without further configuration (the Avantra Agent trusts all incoming certificates by default), client certificates must be configured and installed manually.

In order to enable client authentication in the J2EECONNECT check, a java keystore file containing the accurate certificate must have been generated, stored in a location readable by the Avantra Agent, and defined in this parameter. (If you do not define this parameter, no client authentication will be performed.)

The path of the keystore file can be specified as follows: * Fully qualified path, e.g.. /usr/keys/keystore.ks * Relative path. A relative path is applied to the {avantra-agent}'s cfg directory, e.g. keystore.ks (will resolve to `<syslink`install_dir>/lyceus/cfg/keystore.ks.)

Password for an optional integrity check of the keystore. If you specify this parameter, the used keystore is checked for integrity, otherwise, the keystore is loaded without an integrity check. For this to work, the keystore must have been stored using the same integrity password before.

Indicates the type of the keystore specified in J2EEKeystoreName. The keystore type must exactly correspond to the type of the used java keystore. If a keystore is specified but not a keystore type, pkcs12 is used as the default keystore type.

The Avantra Agent connects the Java instance at the P4 port, as SAP Visual Administrator does. If this TCP/IP port has been changed from its default value, you need to adapt J2EEP4Port to the correct value.

The Avantra Agent connects the Java instance at the P4 port defined by J2EEP4Port. The J2EEP4TransportType Monitoring Parameter defines the transport layer (or protocol) used for this connection. By default, the value is None and the P4 protocol is used.

You can choose SSL in order to use the P4S protocol scheme in case of which the Avantra Agent uses Transport Layer Security (TLS) for the connection.

You can choose HTTPS to use the P4HTTPS protocol scheme. The Avantra Agent then tunnels the connection through HTTPS.

If the number of used system threads exceeds J2EESystemThreadsPoolUsageCrit percent of the maximum thread pool size, the check status is set to Critical.

If the number of used system threads exceeds this value but does not exceed J2EESystemThreadsPoolUsageCrit percent of the maximum thread pool size, the check status is set to Warning.

Per default, the response times of all server processes are used to get the overall average response time of an instance. If you have multiple server processes, and most of them perform well but a few very bad, the overall response time may be affected and display a false alert.

This is where JavaASAvgRespTimeConsiderBest will help. It defines the percentage of the best performing server processes used to calculate the overall server response time. The remaining will not be considered. If, for example, you set it to 50, it will only consider the best 50 percent of your server response times, i.e. if you’ve got 6 servers, only the best 3 response times of those 6 servers will be compared to the thresholds. The default value of the parameter is 100 %, which corresponds to the original behavior of the check, that all server processes are used to calculate the overall value.

If the JARM average response time exceeds this value the check status is set to Critical.

Defines if or if not the JavaASAvgRespTime check resets the JARM statistic records. By default it does. There is no need to change this value unless you use other tools that also try to reset the JARM statistic records.

If JARM average response time exceeds this value but does not exceed JavaASAvgRespTimeCrit, the check status is set to Warning.

The Avantra Agent tries to determine the HTTP port of a Java SAP Instance automatically from the instance profile entries ICM/SERVER_PORT_nn with protocol HTTP (for pre 7.10 instances ICM/HTTP/J2EE_nn); by default 5<sysno>00 is used.

If an HTTPS port is detected in the profile as well, the HTTPS port will be preferred to the HTTP port, and the connection will be established using SSL and the HTTPS port. To overrule this behavior, you may set JavaHttpPort, which in turn overrides HTTPS and forces the usage of HTTP on the specified port.

If detection fails and the default port is wrong, JavaHttpPort may be used to force-set the HTTP port.

The Avantra Agent tries to determine the HTTPS port of a Java SAP Instance automatically from the instance profile entries ICM/SERVER_PORT_nn with protocol HTTPS (for pre 7.10 instances ICM/HTTPS/J2EE_nn);. If no HTTPS port is detected, HTTPS won’t be used by default.

If both HTTP and HTTPS ports are detected in the profile, the HTTPS port will be preferred over the HTTP port, and the connection will be established using SSL and the HTTPS port. See the description of JavaHttpPort for further details.

If detection fails for an HTTPS port, JavaHttpsPort may be used to force-set the HTTPS port, overruling any JavaHttpPort setting.

If the long-running threads count of any cluster node of an AS Java is equal to or above this setting, the check status of JavaLongRunningThreads will be Critical, otherwise, Warning if higher than 0.

If the percentage of running server nodes of an SAP J2EE instance compared to all nodes is equal to or below this value, the check status will be Critical.

If the percentage of running server nodes of an SAP J2EE instance compared to all nodes is equal to or below JavaServerNodesRunningPctWarn but still above JavaServerNodesRunningPctCrit, the check status will be Warning.

When SAPControl is available and configured for a system / instance in the Avantra WebUI (see ), it’s possible to monitor the Java by means of SAPControl instead of the traditional JMX/P4 monitor.

The SAPControl setting might be useful if the JMX/P4 monitor doesn’t work reliably or is not accessible for some reason.

If the time spent on garbage collection is equal to or above JVMGCRatioCrit percent of the JVM total runtime, the check status will be Critical.

If the time spent on garbage collection is equal to or above JVMGCRatioWarn percent of the JVM total runtime, but still below JVMGCRatioCrit, the status of the GC ratio sub-check will Warning.

If the amount of the Java virtual memory used exceeds JVMMemoryUsageCrit percent of the available memory, the check status is set to Critical.

If the amount of the Java virtual memory used exceeds this value but does not exceed JVMMemoryUsageCrit percent of the available memory, the check status is set to Warning.

Do not use unless instructed by the Avantra Support Team.

Special purpose parameter for setting the relative Jar search path of Avantra Agent. Do not use unless instructed by the Avantra Support Team.

Special purpose parameter for setting the Jars loaded by Avantra Agent. Do not use unless instructed by the Avantra Support Team.

The MessageServer daily check checks the parameter rdisp/msserv_internal according to SAP recommendations and standard configurations. If this parameter has a different value and you know that your systems are running safely with your value, you can override the default behavior of the MessageServer daily check with this monitoring parameter.

Set the port of your rdisp/msserv_internal parameter value. Typical values are 39xx. You can also use regular expressions, use 39\d\d to allow all ports from 3900 to 3999.

Deprecated

Per default, Avantra Agent collects performance data for ABAP task types DIALOG and additionally for the task types listed in this parameter. Task type DIALOG is always recorded so it is not required to specify it using PerfDataCollectABAPTaskTypes. Per default, performance is also collected for background jobs and HTTP requests.

You can list possible task types using SAP transaction Workload (ST03). For example, possible values are AUTOABAP, AUTOCCMS, AUTOJAVA, AUTOTH, BACKGROUND, BUFFER SYNC, DDLOG CLEANUP, DEL. THCALL, DIALOG, HTTP, RFC, RPCTH, SPOOL, UPDATE, UPDATE2.

Controls whether or not Performance Data Collection is turned on for Systems. If you do not want the Avantra Agent to collect performance data you may remove the flag.

Use this monitoring parameter to configure the Predictive Analytics engine for the SAP Instance. By default the engine is configured as Balanced.

Defines a list of Daily Check details that are considered relevant for the Daily Check status, i.e. the status of which contributes to the overall status. By default, the parameter is not defined, i.e. all Daily Check details contribute.

If you define an empty list, no Daily Check detail will contribute. In this case, the status of the Daily Check will be always Unknown.

If an SAP Instance is no longer discovered by any Avantra Agent, it will be marked in Avantra as NOT_SEEN. (In this state, it can only be removed from the system manually using Avantra WebUI.)

If it is discovered again by any Avantra Agent within the RemoveFromDBDelay days period, the NOT_SEEN flag is simply removed.

If the SAP Instance is not discovered by any Avantra Agent for RemoveFromDBDelay days, it will be removed from the Avantra Database.

Starting from RFCConnectErrsCrit failed RFC connection attempts the check status will turn from Warning to Critical.

This parameter allows you to configure the protocol to access the SAPControl Web Service Interface of an SAP instance.

If you specify OFF, SAPControl won’t be used for the instance.

If you specify Adaptive, the SAPControl connector will use Windows Named Pipes / Unix Domain Sockets to connect to the SAPControl Web Service, unless the optional SAPControl User is defined for the SAP System, see Defining SAP Systems. If the SAPControl User is defined, HTTP/HTTPS will be used automatically.

If you specify NamedPipes, the SAPControl connector will use Windows Named Pipes / Unix Domain Sockets to connect to the SAPControl Web Service of the underlying instance, regardless of its type. Make sure the Agent OS user has sufficient permissions to access the Named Pipe / Domain Socket.

If you specify HTTP, the SAPControl connector will use HTTP to connect to the SAPControl Web Service of the underlying instance, regardless of its type. The HTTP port defaults to 5<sysno>13, unless the services file (i.e. /etc/services on Unix, C:\Windows\System32\drivers\etc\services on Windows) contains an entry sapctrl<sysno> (HTTP) defining a different port. When you specify this option, you have to define a SAPControl User in the corresponding SAP System properties; see Defining the SAPControl User.

If you specify HTTPS, the SAPControl connector will use HTTPS to connect to the SAPControl Web Service of the underlying instance, regardless of its type. The HTTPS port defaults to 5<sysno>14, unless the services file (i.e. /etc/services on Unix, C:\Windows\System32\drivers\etc\services on Windows) contains an entry sapctrls<sysno> (HTTPS) defining a different port. When you specify this option, you have to define a SAPControl User in the corresponding SAP System properties; see Defining the SAPControl User.

If host name detection fails, then the SAP host with the defined value is used.

Configure a route string describing a connection between two hosts using one or more SAProuters.

Starting from SCSMsgSrvConnectErrsCrit failed message server connection attempts the check status will turn from Warning toCritical.

Define the port to connect to the Java_Scs or Abap_Scs Messaging Server. By default, this is 81<system_number>.

If messaging server’s HTTPS port detection fails, then the defined value is used.

See the description of SNCLibraryPath.

See the description of SNCSecuDir.

The Avantra Agent waits TimeOutCCMS seconds before it cancels CCMS Custom Checks.

On very slow systems with a lot of CCMS Custom Checks defined it may be necessary to increase this parameter.

The Avantra Agent waits TimeOutFullCheck seconds before it cancels a running Daily Check.

It might be necessary to increase the timeout on very big systems (in terms of data size) and depending on the set of active checks.

The Avantra Agent waits TimeOutJ2EEConnect seconds before it cancels a running Java SAP Instance connection attempt.

Avantra Agent waits TimeOutMediumCheck seconds before it cancels a running Medium Check Cycle. On very slow systems it may be necessary to increase this parameter.

The Avantra Agent waits TimeOutMsgSrvConnect seconds before it cancels a connection attempt to the Abap_Scs or Java_Scs message server.

The Avantra Agent waits TimeOutRFCConnect seconds before it cancels a running RFC connection attempt.

SAPControl is used for several operations during monitoring, like remote detection of instances for agentless SAP system monitoring, certain checks, etc. This monitoring parameter allows you to configure the connect and read timeout for those SAPControl operations per instance.

The Avantra Agent waits TimeOutTREXConnect seconds before it cancels a running TREX connection attempt.

This parameter allows you to reconfigure the mapping of the check states of a TREX Alert Server to the check states of Avantra. You must specify a comma-separated list of numbers, which get assigned in order of their appearance to the Avantra states 2 (CRITICAL), 1 (WARNING), 0 (OK), -1 (UNKNOWN), -2 (DISABLED). Not all states must be specified, so it is sufficient to assign the first 3 values to get a proper mapping.

Optionally, you can specify mappings for the check name in addition to the default mapping, or you can simply change the mapping for individual checks. Consider the following examples:

2,1,0 : All TREX checks use mapping 2,1,0

2,1,0;TREX Alertserver Start: 3,2,1 : All TREX checks use mapping 2,1,0 except for check TREX Alertserver Start, which uses 3,2,1

TREX Disk Usage: 2,1,0; TREX CPU Usage: 2,1,0 : All TREX checks use the default mapping 3,2,1,0 except for checks TREX Disk Usage (2,1,0) and TREX CPU Usage (2,1,0).

The default assignment is 3 → 2 (CRITICAL), 2 → 1 (WARNING), 1 → 0 (OK), 0 → -1 (UNKNOWN)

Starting from TREXConnectErrsCrit failed RFC connection attempts, the check status will turn from Warning to Critical.

If detection of TREX landscape id fails, then the defined value is used.

If disabled, WD_Certificates will check the trust chain to the root certificate authority. If enabled, the trust chain is not verified, so that self-signed certificates will be OK.

If the number of days before the SSL certificate of the SAP Web Dispatcher expires is below this value, the check status is set to Critical.

Same as WDCertDaysCrit above, only this is the threshold for Warning check status.

Starting from WDConnectErrsCrit failed connection attempts the check status will turn from Warning to Critical.

If the number of used connections exceeds WDConnUsageCrit percent of the maximum number of connections available, the check status is set to Critical.

If the number of used connections exceeds this value but does not exceed WDConnUsageCrit percent of the maximum number of connections available, the check status is set to Warning.

If the number of used queue entries exceeds WDQueueUsageCrit percent of the maximum number of entries available, the check status is set to Critical.

If the number of used queue entries exceeds this value but does not exceed WDQueueUsageCrit percent of the maximum number of queue entries available, the check status is set to Warning.

If the number of used worker threads exceeds WDThreadsUsageCrit percent of the maximum number of worker threads available, the check status is set to Critical.

If the number of used worker threads exceeds this value but does not exceed WDThreadsUsageCrit percent of the maximum number of worker threads available, the check status is set to Warning.

WorkProcDiaStatusCrit controls the optional part of the WorkProcesses check.

You can define a list of work process status (i.e. On Hold, Stopped, Shutdown, Reserved, Starting) and / or reasons (from the reason column of SAP transaction Work Process Overview`SM50`). If a work process is found with either the defined status or reason the Check will turn to Critical.

Controls the first mandatory sub-check of WorkProcesses.

If the number of non-OK work processes exceeds WorkProcDiaStatusNOkPctCrit percent of the total number of work processes, the WorkProcesses check will turn to Critical.

Controls the first mandatory sub-check of WorkProcesses. Warning threshold corresponding to WorkProcDiaStatusNOkPctCrit above.

If the number of non-OK work processes exceeds this value but not WorkProcDiaStatusCrit percent of the total number of work processes, the check will turn to Warning, unless any other of the executed sub-checks is Critical.

WorkProcDiaStatusWarn controls the optional part of the WorkProcesses check.

You can define a list of work process status (i.e. On Hold, Stopped, Shutdown, Reserved, Starting) and / or reasons (from the reason column of SAP transaction Work Process Overview`SM50`). If a work process is found with either the defined status or reason the Check will turn to Warning, unless any other of the executed sub-checks is Critical.

Controls the second mandatory sub-check of WorkProcesses.

If the elapsed CPU time of the dialog work process with the lowest CPU time is ≥ WorkProcDiaTimeUsageCrit % of the total elapsed time between two snapshots, the Check Result will be Critical.

Controls the second mandatory sub-check of WorkProcesses.

If the elapsed CPU time of the dialog work process with the lowest CPU time is ≥ WorkProcDiaTimeUsageWarn but < WorkProcDiaTimeUsageCrit % of the total elapsed time between two snapshots, the Check Result will be Warning, unless any other of the executed sub-checks is Critical.
