# Server - Monitoring Parameters

Here you will find detailed information about monitoring parameters for Server monitored objects.

Monitoring parameters are the mechanism for you to configure how your systems are monitored. They are how you set configuration of how the agent runs, how checks are executed, thresholds for checks (when does a check go critical or warning) and much more. All Monitoring Parameters have a carefully chosen default value. As soon as you add a new system, Avantra uses these defaults. You may change these defaults by defining a parameter and by modifying its values. Monitoring Parameters can be defined for a single system, or for collections of systems using Monitoring Parameter Sets. You can also define your own Custom Monitoring Parameters for use within Custom Checks and automations.

## AgentConnectRoute

Define routing string for use with the avantra-gateway

| Description It is recommended to use The Route Configurator instead of configuring this parameter directly.

If the Avantra Server connects to the Avantra Agent through one or more avantra-gateways, you can define this value.

Reference Data

    URL       ::==  ( target | reverse) ['?' query ]
    target    ::==  protocol '//' host ':' port
    reverse   ::==  '//' reverse-id
    query     ::==  param {'&' param}
    protocol  ::==  'a5' | 'a5s'

## SAPInstanceDetection

Control SAP Instance Auto Discovery

Description

This parameter controls the SAP Instance Auto Discovery algorithm of the Avantra Agent.

By default, only SAP Instances with an instance profile file ending on the `hostname` (on Physical Servers) or the Virtual Cluster Server Name (on Virtual Cluster Servers) are monitored. If your profiles are named differently and you are using logical hostnames, first, have a look at SAPLogicalHostDetection and SAPLogicalHostResolution.

Allow Mode

  You can define a list of SAP Instance names for the SAP Instances to be discovered on the corresponding Server. In this mode, define all SAP Instances in question as a formatted string.

| Only if the Avantra Agent cannot find instance profiles after setting SAPLogicalHostDetection and SAPLogicalHostResolution, you should consider using SAPInstanceDetection in allowlist mode.

Deny Mode

  Let the Avantra Agent automatically discover all the SAP Instances and define a list of SAP Instance names that should be excluded. In this mode, define all excluded SAP Instances as a formatted string and add the keyword `EXCEPT` as a prefix to this list. You can even use `EXCEPT *` to turn off SAP Instance Auto Discovery completely.

You can change this behavior by using the keyword `ALL`. The keywords `ALL` and `EXCEPT` can be combined.

| Do NOT use the value `ALL` only unless instructed by the support. In particular, do NOT use the value `ALL` in conjunction with Virtual Cluster Servers.

Example 1. Example for an Allow List

`BEN: pinot_BEN_00, merlot_BEN_01; P11: riesling_P11_00`

with `BEN` and `P11` the Real SAP SID of the SAP Instances followed by the corresponding instance names, in case of `BEN` separated by a comma.

Example 2. Example for a Deny List

`EXCEPT BEN: merlot_BEN_01`

with `BEN` the Real SAP SID of the SAP Instances followed by the corresponding instance name.

Example 3. Discover no SAP Instances at all

`EXCEPT *`

Reference Data

Configures | SAP Instance Auto Discovery
Unit | Formatted String: `[ALL] [EXCEPT [*]] <SID1>:<InstPrf11>, <InstPrf12>, …​ ; <SID2>:<InstPrf21>, <InstPrf22>, …​; …​`

## SAPInstanceDetectionMode

Control SAP Instance Auto Discovery

Description

This parameter determines how SAP Instances are discovered on the server. SAPInstanceDetectionMode has three values: `PROFILES`, `SAPServices`, and `AUTO`. In the first case, the filesystem is scanned for SAP instance profiles, which is the default behavior. In the case of SAPServices, the `sapservices` file is parsed and SAP instance profiles are detected based on the findings. For the AUTO search method, profiles are determined from the `sapservices` file if it is present and can be read. Otherwise, a filesystem scan for SAP instance profiles will be performed.

Reference Data

Configures | SAP Instance Auto Discovery
Unit | Enum

## SAPInstanceProfiles

Control SAP Instance Auto Discovery

| This parameter is deprecated and supported only for backward compatibility. Please use the improved SAPInstanceDetection parameter instead.

Reference Data

Configures | SAP Instance Auto Discovery
Unit | Formatted String: `[ALL] [EXCEPT [*]] <SID1>:<InstPrf11>, <InstPrf12>, …​ ; <SID2>:<InstPrf21>, <InstPrf22>, …​; …​`

## SAPInstanceProfilePaths

Specifies additional directories containing SAP Instance profiles or/and paths to SAP Instance profile files.

Description

There are specified directories that contain SAP Instance profiles, or the direct paths can be specified to the certain profile files. These profiles then are examined for systems and used for system detection.

Reference Data

Configures | SAP Instance Auto Discovery
Default Value | “”
Unit | String

## SAPLogicalHostDetection

Lets the Agent detect instances using Logical Host Names automatically.

Description

If the hostname used by the instance (SAPLOCALHOST) is a Logical Host Name and doesn’t match the Server Name defined in Avantra, monitoring will not be performed. But if this parameter is activated on the corresponding SAP System, the Agent will do a `/etc/hosts` and DNS lookup for the Logical Host Name, and if the name resolves to a matching IP address, the instance will be monitored by the Agent.

Reference Data

Configures | Instance Detection
Default Value | false
Unit | Boolean
Monitoring Exception Parameter available | No

! Do not use this parameter in conjunction with Virtual Cluster Servers. Otherwise, instances might be detected twice - once for the logical host and once for a VCS with the corresponding host name, which may lead to mutual cancellation.

## SAPLogicalHostResolution

Allows you to define custom host name / ip mappings augmenting Logical Host Name resolution.

Description

In addition to the SAPLogicalHostDetection parameter, this parameter can be used to define IP addresses or host names for Logical Host name resolution. Normally the automatic resolution using the hosts file or DNS will work, but in case of DNS problems or Agentless Monitoring, this parameter can be set to customize the resolution. On a per-host basis, mappings of multiple host names to an IP address or host name can be defined. If Logical Host detection is active but this parameter doesn’t provide a mapping, the detection falls back to the hosts file / DNS mapping.

The format of the parameter looks as follows:

    logical-host-name-mappings ::=  logical-host-name-mapping { ';' logical-host-name-mapping }
    logical-host-name-mapping  ::=  real-name ':' logical-name { ',' logical-name }
    real-name                  ::=  ip-address | host-name
    logical-name               ::=  host-name

The following examples show how to set the parameter:

`192.168.10.105: baker, berthe` `192.168.10.105: baker, berthe; 192.168.10.106: baltimore`

Reference Data

Configures | Instance Detection
Unit | String

## SAPSidAdmMapping

Defines mapping from sid to custom sidadm users who don’t follow the default <sid>adm naming scheme.

Description

The <sid>adm user reads the user environment of the bootstrap instance, but this user can be arbitrary. Therefore the correct mapping can be specified from system id (sid) to the user with this parameter, for example:

WDB: wdmadm

It tells the Avantra Agent that the sidadm of system WDB is 'wdmadm' and provides the environment of wdmadm for system WDB.

This monitoring parameter allows you to control Virtual Cluster Server detection (only applicable to Avantra Agents >= Avantra Version 20.11.7). There are three possible settings for this parameter: Auto (default), Local, Master.

Auto

  In the current implementation, Auto always defaults to Local.

Local

  The Avantra Agent tries to bind a listener to the virtual IP address (specified on the Virtual Cluster Server) and connects to that listener. If successful, the cluster server is reported to be active on the Avantra Agent.

Master

  The Avantra Agent triggers the Avantra Server / Avantra Server to connect to the Avantra Agent, reachable via a virtual IP address. If the reached Agent matches the calling Agent, the cluster server is reported to be active on the Avantra Agent.
