Default Parameters for HanaGCStatsTest

The purpose of this test is to collect metrics related to garbage collection in each volume and provide insight into the health of the garbage collection process if it is running and working efficiently. Looking at the metrics, administrators can determine the count of started, processed and queued jobs, and also the rate of queued and processed jobs,which helps them to investigate any bottleneck conditions before the entire system starts running out of space.

This page depicts the default parameters that need to be configured for the HanaGCStatsTest test.

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• In the HOST text box, specify the IP address of the target server that is being monitored.

• In order to monitor a SAP HANA database server, a special database user account with Monitoring privileges has to be created in every SAP HANA database instance that requires monitoring. The syntax of the script that is used for user creation is discussed in Pre-requisites for Monitoring the SAP HANA Database Server.

  The name of such a USER has to be specified here.

• Enter the password of the specified User in the PASSWORD text box and confirm it by retyping in the CONFIRM PASSWORD text box.

• In the ISPASSIVE flag, if the value chosen for this parameter is Yes, then the SAP HANA database server under consideration is a passive server in a SAP HANA cluster. No alerts will be generated if the server is not running. Measures will be reported as “Not applicable” by the agent if the server is not up.

• Once the above values are provided, click on the UPDATE button to register the changes made.

When changing default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz*” and $port will be changed to “80” when configuring a test.
