SAP HANA Monitoring

Creating a new SAP HANA monitor

Prerequisites for monitoring SAP HANA metrics: Click here

Using the REST API to add a new SAP HANA monitor: Click here

To create a SAP HANA DB server monitor, follow the steps given below:

Click on New Monitor link.
Select SAP HANA under Database Servers.
Specify the Display Name of the SAP HANA monitor
Enter Host Name of HANA server.
If Using SAP HANA Cloud Platform,
- Select SAP HANA Cloud Platform.
- Enter Cloud Account Name, UserName and Password.
Enter Port as IndexServer port, default port is 30015.
You can enter your own credential details or select pre-configured credentials from Credentials Manager. If you wish to enter your own credentials, specify SAP HANA username and password details for this monitor.
Enter Database Username and Database Password.
Enter Instance Name.
On checking the SSL is enabled box, secure connections will be established using SSL encryption.
In the hostnameInCertificate field, enter the host name to be used to verify the server’s identity in the .
Specify the Timeout value in seconds. Default value is 20 seconds.
Set the Polling Interval.
If you are adding a new monitor from the Central Server, select a Probe Server.
Choose the Monitor Group from the combo box with which you want to associate SAP HANA Server Monitor (optional). You can choose multiple groups to associate your monitor.
Click Add Monitor(s). This discovers SAP HANA server from the network and starts monitoring them.

Prerequisites:

Need to copy ngdbc.jar into the location /working/classes. ngdbc.jar can be copied from installed SAP HANA Client folder. Click here to download SAP HANA Client
If HANA is running On-demand, in addition to the above, SAP Cloud Platform SDK is needed. However, this is not needed for HANA On-premise. Click here to download SAP Cloud Platform SDK. The downloaded zip should be extracted under <Applications Manager Home>/working/hanacloud folder. After extracting need to verify whether <Applications Manager Home>/working/hanacloud/tools folder is available.
Need to restart APM after performing the above steps.
To effectively monitor SAP HANA, the SAP HANA DB User must have the below privileges,
- System privilege CATALOG READ
- Object privilege SELECT on the schema _SYS_STATISTICS
To grant these privileges to the user, execute the below statements in SAP HANA SQL console.(Replace USER_NAME with actual HANA DB Username)
- GRANT MONITORING to <USER_NAME>
- CALL GRANT_ACTIVATED_ROLE ('sap.hana.admin.roles:Monitoring','<USER_NAME>')

Monitored Parameters

Go to the Monitors Category View by clicking the Monitors tab. Click on SAP HANA under the Database Servers Table. Displayed is the SAP HANA bulk configuration view distributed into three tabs:

Availability tab gives the Availability history for the past 24 hours or 30 days.
