EKG: Remote monitoring of running processes over HTTP

This library lets you remotely monitor a running process over HTTP. It provides a simple way to integrate a monitoring server into any application.

Getting started

Adding monitoring to your application is simple. Just launch the monitoring server as soon as your application starts

import System.Remote.Monitoring.Wai

main = do
     forkServer "localhost" 8000
     ...

and then visit http://localhost:8000/ in your web browser.

To make full use out of this module you must first enable GC statistics collection in the run-time system. To enable GC statistics collection, either run your program with

+RTS -T

or compile it with

-with-rtsopts=-T

The runtime overhead of -T is very small so it's safe to always leave it enabled.

JSON API

The monitoring server also lets you to retrieve the stats as JSON. Simply send the server an HTTP GET request with the Accept header set to "application/json":

curl -H "Accept: application/json" http://localhost:8000/

You can use the JSON API to e.g. write applications that monitor other applications.
