=== Metrics

The *Metrics* overview provides agent-specific metrics,
which lets you perform more in-depth root cause analysis investigations within the APM app.

If you're experiencing a problem with your service, you can use this page to attempt to find the underlying cause.
For example, you might be able to correlate a high number of errors with a long transaction duration, high CPU usage, or a memory leak.

If you're using the Java Agent, you can view metrics for each JVM.

Breaking down metrics by JVM makes it much easier to analyze the provided metrics:
CPU usage, memory usage, heap or non-heap memory,
thread count, garbage collection rate, and garbage collection time spent per minute.
