I haven't looked at its implementation, so be careful if it does DNS (or system call) query every time it is used, it may slow down the processing, in that case you can just store in another variable and use it instead.

I ended up using $HN().

Hello,

We have multiple Kamailio 4.4.x servers and I am setting up stats tracking.  I would like to track the stats for each individual Kamailio server separately like so:

kamailio_1.sip.register.count

kamailio_2.sip.register.count

kamailio_3.sip.register.count

The problem is that we use one common file (in version control) for our Kamailio configuration.  Thus, I can’t just hardcode the hostname into the file because it will be the same for each server.

Does anyone have a solution for me?  Is there a variable that provides the hostname or is there something else I can do?

Ideally, I’d love to be able to do something like this.

statsd_incr($host_name + “.sip.register.count");

one option would be to define it via command line parameter with -A option. Your start script can set it using the usual shell scripts.

Cheers,
Daniel
