HANA Peak Memory

Dear Colleagues,

We received an alert from Solution Manager about HANA peak memory utilization reaching to 96%.

We did not run any trace at that time. I do have time stamps with me for the peak memory.

Is there a way to check what SQL statements or other activities would have run during that time stamp?

Thank you.

Warm Regards,

Harshad

    Hi Harshad please check system monitoring tables

    SAP HANA Reference: M_MEMORY

    SAP HANA Reference: M_SERVICE_COMPONENT_MEMORY

    SAP HANA Reference: M_MEMORY

    To display the current size of the Used Memory, you can use the following simple SQL statement

    select HOST, round (INSTANCE_TOTAL_MEMORY_USED_SIZE/1024/1024/1024, 2) as "Used Memory GB" from M_HOST_RESOURCE_UTILIZATION.

    hdbcons is a tool to provide information about the actual used memory, the peak memory,

    the throughput of the different allocators, etc.
