[SR-Users] Collecting stats from Kamailio.cfg using Kamailio_exporter Prometheus

[Ovidiu Sas]

Hello Hisham,

Yes, you can. Here are the steps:
 1. load the jsonrpcs and jansson module,
 2. collect your data using the jsonrpc_exec() function,
 3. handle the data using the jansson methods,
 4. store the data in a new metric(s) using the prom_gauge_set() function.

Then let the prometheus scrape the metrics and use grafana to plot them.
Enjoy!

Ovidiu Sas

My question is, can I use kamailio_exporter to scrape data onto Prometheus from the same JSON RPC script running for NodeRed? Or, do I need to rewrite a new script/code for Kamailio_exporter to scrape data?
