HTTP Pinger

A small utility application to make a GET request to a configurable HTTP URL, measure the latency and push it to Carbon. The utility is useful to recreate rare network issues or simply measure latencies.

Usage

The application tries to have sane defaults and could be started without any additional parameters. Here's a list of all CLI parameters:

$ ./http-pinger -help
Usage of ./http-pinger:
  -carbon-host="localhost": Carbon host/IP.
  -carbon-interval=1m0s: Interval to write to Carbon.
  -carbon-namespace="http-pinger": Where the Carbon data should be stored in Graphite.
  -carbon-port=2003: Carbon port.
  -http-interval=10s: HTTP test interval.
  -http-timeout=30s: HTTP request socket timeout.
  -url="http://localhost/": The URL to issue the GET to.
