I use a mix of the above...

With kamailio I export that stats I want via http:


event_route[xhttp:request] {
    # Verify request come from localhost
    if(src_ip!=127.0.0.1) {
        xhttp_reply("403", "Forbidden", "text/html", "<html><body>Forbidden</body></html>");
        xlog("L_WARN", "[HTTP] Unauthorized access from: $si\n");
        exit;
    }

    # Metrics endpoint
    if ($hu =~ "^/statistics") {

        ... build a $var(metrics_json) with the metrics you want, must be JSON format ...

        }
        xhttp_reply("200", "OK", "application/json", "$var(metrics_json)");
    }
    return;
}


Then in telegraf I use the httpjson module to gather the metrics:

...
[[inputs.httpjson]]
  name_override = "kamailio"
  servers = [ "http://127.0.0.1/statistics" ]
  method = "GET"
...



This is an example:

joel@sbc-dev:~$ curl -q http://127.0.0.1/statistics 2> /dev/null | python -m json.tool

We have all those metrics available now in influxdb, then, as others have stated, Grafana is your best friend to make those metrics look nice.


Hope these little snippets help you and anyone else getting started with Kamailio metrics.


Cheers, 
Joel.

Hello List,

I thought about some kind of Kamailio stats source (like registered users, calls active and some other things) to collect them into influx dB and draw them with grafana. 

How do you solved that? 

Timer based routes or statsd or whatever? 

Kind regards
Karsten Horsmann
