I am wondering if anyone has a clever way to remotely
monitor a Kamailio
1.5 server. I am not looking for the standard monitoring, what I am
looking to achieve is catching situations where my upstream carrier is
having problems. We have a certain level of 404, 500, 503 errors
throughout the day which are not indicative of a major carrier problem. I
want to be able to monitor the ratio of properly setup calls to failed
setups - so I can know when a carrier is having issues and is responding
with many 503 errors.
Any push in the right direction would be greatly appreciated.
Hi Geoffrey,
you probably do this already, but i've found the ASR rate (200 OK - failures)
which we generate from our accounting a really helpful value to quickly notice
a QoS problem for a certain carrier. Especially if you can compare against
past data, like the last day, or last week. If you then add NER (200 Ok -
"carrier failures") it gives you an even better picture.
You probably should be able to build something like this also with the htable
approach Daniel suggested and some web graph tool.
Cheers,
Henning
