I'm using kamailio with the dispatcher module. I would like to know if there are some API to get an average of the service execution time. In other words, I need to get the time between sending the request and receiving the response for every request, but also to have this values separate per server.

I know also that this could be a little heavy for the dispatcher, but for some test I need this information.

Hi Giuseppe,

have you already looked to the "benchmark" module? It can be used to create arbitrary timers in the configuration file. If you need to have it per request and response, you probably could just include the sending time in a special message header in the sent out request. They are several pseudo-variables available which contains timestamps in different formats.

If you want to benchmark the complete server, an external probe should be the way to go. Just send test requests e.g. with sipp, it can also output the response time.

Cheers,

Henning
