I’m looking to identify heap utilization as a percentage of max heap. This would be a ratio:

```auto
com.dynatrace.builtin:pgi.jvm.usedmemory/com.dynatrace.builtin:pgi.jvm.committedmemory

```

Is this something that I just need to calculate myself or is this available as a separate subscribable metric?

Dynatrace might have an infograph that sums the two for an overall. You could also look into creating a Custom Chart to sum that up. There is a heap max for a custom chart as well:
