Prometheus client library for Nim

This is a Nim client library for Prometheus. Features include:

• Multiple metric types:
  • Counters
  • Gauges
  • Histograms
• Nim-specific collectors:
  • Async collector (logs statistics about pending futures, timers and callbacks from Nim's async event loop)
  • GC collector (logs heap allocation statistics, compile with -d:nimTypeNames to get granular information about the allocated object types)

Usage

Add this into your .nimble file:

requires "prometheus"

You then need to serve the Prometheus metrics over HTTP, if you're using Jester you can do so by simply:

routes:
  get "/metrics":
    let data = generateLatest()
    resp Http200, {"Content-type": "text/plain"}, data

Testing

Run:

nimble test
