Custom metric - Sum of metric from all agents

[andrew_lavesper]

I would like to get the sum of a metric as a single number from all agents. Specifically, Tomcat Busy Threads. I would like to get the current cumulative total of the busy threads of all the agents.

Yes you can. Use the API to pull back the ThreadsBusy metric for all relevent process Group Instances, sum across these values.

As a newbie, could you explain the steps required to do something like this? Is it possible to configure this from the console?

This cannot be done from the GUI. You would need to write some code to call the Dynatrace API to pull back the metrics. Full doc on the API is available, including lots of examples: https://www.dynatrace.com/support/help/extend-dyna...
