################### JVM Instrumentation ###################

The metrics-jvm module contains a number of reusable gauges and :ref:metric sets <man-core-sets> which allow you to easily instrument JVM internals.

Supported metrics include:

• Run count and elapsed times for all supported garbage collectors
• Memory usage for all memory pools, including off-heap memory
• Breakdown of thread states, including deadlocks
• File descriptor usage
• Buffer pool sizes and utilization
