JVM Heap Used percentage

[dambala_rosyla1]

Hi Team,

We want to show a metric "JVM memory heap used percentage" in dashboard. I could see " JVM runtime free memory" and "JVM runtime total memory" metrics are already available in Dynatrace. Can you please suggest if we can use a simple formula to get JVM memory heap used percentage.

Regards,

Rosyland

I dont see the ability to do that, I would recommend tossing in a RFE requesting that functionality and hopefully it will be built into a future release!

The JVM Heap Used percentage can be achieved in Data Explorer.

Hello @Shirai

I require your help in determining the percentage of memory pool utilized for the following:

((builtin:tech.jvm.memory.pool.committed:filter(and(or(in("dt.entity.process_group_instance",entitySelector("type(process_group_instance),softwareTechnologies(~"IBM_INTEGRATION_BUS~")"))))):splitBy("dt.entity.process_group_instance"):max:sort(value(max,descending))) / (builtin:tech.jvm.memory.pool.used:filter(and(or(in("dt.entity.process_group_instance",entitySelector("type(process_group_instance),softwareTechnologies(~"IBM_INTEGRATION_BUS~")"))))):splitBy("dt.entity.process_group_instance"):max:sort(value(max,descending)))) * (100)
