SAP HANA COCKPIT NOTES 26:How to trouble shoot hana cockpit issues

troubleshooting method 1:

If you encounter issues with SAP HANA cockpit, you can use XS CLI commands to view services logs and application status. You can execute the XS CLI commands on the machine where the cockpit is installed, using the <SID>adm account, or remotely using the XSA Client. For complete details on logging into the SAP HANA XS advanced runtime console and on the XS CLI: Application Management commands, see SAP HANA Developer Guide for SAP HANA XS Advanced Model. 

troubleshooting method 2:

You can investigate potential issues by viewing the log file of a specific service with the command                                                          xs logs <APP> 

where <APP> is the name of the application whose log-file details you want to display in XS apps cmd.

EX:

In the log of cockpit-collection-svc, if you see: A collection could not be submitted for execution because the worker thread pool is exhausted, then consider increasing the collection worker thread pool in the data collection settings through the cockpit manager. Increase the threads incrementally, rechecking the log each time, until the issue is resolved.
