This was asked back in 2020 but now that we’re 2 to 3 years out I figured I’d ask again.

Also, with Dynatrace’s push for API first I thought it might be relevant to ask again.

We have a need to trigger this when a specific process reaches 86% of heap for 5 minutes.&nbsp; That way we can get a dump right before it freezes up.

(builtin:tech.jvm.memory.pool.used:filter(and(or(in(“dt.entity.process\_group\_instance”,entitySelector(“type(process\_group\_instance),entityId(~“PROCESS\_GROUP\_INSTANCE-84A1A852CED43316~”)”))))):splitBy():max) / (builtin:tech.jvm.memory.pool.max:filter(and(or(in(“dt.entity.process\_group\_instance”,entitySelector(“type(process\_group\_instance),entityId(~“PROCESS\_GROUP\_INSTANCE-84A1A852CED43316~”)”))))):splitBy():max)\*(100)

We too are looking to automate these on our full stack webspehere applications as we routinely see memory leaks here and with mule.&nbsp; We are looking at ways to automate a mem dump using ansible tower and recycle the service.
