# @pm2/node-runtime-stats

## How does it work?

You can see most of the implementation details in `src/nativeStats.cc`. The plugin sets callbacks

around GC invocations, and during the `prepare` and `check` phases of the event loop, tracks the

amount of time spent in each.

## Metrics collected

```json

{

  "gc": {

    "collections": 0,

    "pause": 0,

    "oldCollections": 0,

    "oldPause": 0,

    "youngCollections": 0,

    "youngPause": 0

  },

  // duration of event loop tick

  "ticks": [

    20,

    10

  ]

}

```
