Hana Monitoring - Some grey metrics

Dear

I completed the managed system configuration and the monitoring setup in solution manager.

I am still missing some metrics. I implemented a few notes and this solved some of the missing metrics but not all.

Anyone got an idea how I could get the following metrics ?

Kind regards

Lucas

    Hi Lucas,

    There are two common potential root causes for grey metrics based on the extractor E2E_DB_ALERTS if the embedded statisticsserver is enabled: Embedded statistics server enabled means: no statisticsserver process listed in the HANA services list and parameter: nameserver.ini -> [statisticsserver]->active=true. Especially with HANA Revisions < 90 HANA may have disabled alerts internally because their data collection runtime was too long. Before HANA Rev 90 these alerts are not automatically enabled again and lead to grey metrics in Solman. See SAP Knowledge Base Article 2131512. 2131512 - HANA alerts continually disabled due to timeout You will see status ‘Disabled’ in table _SYS_STATISTICS.STATISTICS_SCHEDULE for each alert id (column ID) which was switched off by HANA. You can also see the last execution time of the alert check per ID and if this is more than two times the metric frequency in Solman you will get a grey metric. It also means that HANA internally does not check these alert conditions any more. 2. Missing permission for the DB user used by Solman to read the alert data. With the embedded statisticsserver, two additional permissions (in addition to the MONITORING role) need to be granted to the DB user on HANA side. See SAP Note 1917938. If the permissions are missing you get a permission error when executing the following command in HANA studio with the DB user in question: call_sys_statistics.statistics_schedulablewrapper_TEST('Manual',now(),30,1,?)

      Thank you, I will check those out.

      Edit: The notes don't seem really relevant, I will however try to get some more info out of mai_tools. Thanks.

      Edit2:

      I also noticed our LM-Serive could use an update, would this be relevant for these metrics?

      Kind regards
