[SR-Users] kamailio and rtpengine_manage() / rtpengine_delete()

[Julien Klingenmeyer]

Hi Karsten,

I would also monitor the below stats in your case:

  *   Total timed-out sessions via SILENT_TIMEOUT: for calls being cut because of no RTP media flow
  *   Total timed-out sessions via FINAL_TIMEOUT: for calls timeout
(assuming you have configured a correct value for both corresponding settings in your rtpengine config file)

For each proxy you could also check the difference between total of delete requests and total of answer requests: there should be one delete for one answer.

And one more thing: monitor the ongoing sessions for each of your RTPEngine proxies. If number increases significantly for no reason it could show some issues in the RTPEngine cleanup routine process.

Note also there is a nice new feature in the last rtpengine releases to get all stats in a json format (the list jsonstats CLI command).
From that you could easily create a monitoring system based on the metrics you want.

Cheers

Julien

 Hi list,

I use rtpengine 7.2.1 branch with kamailio 5.2.x and 5.3.x in different setups.
Due to some issues with my 5.2.x config I saw the "Total timed-out sessions via TIMEOUT" grow but  "Total regular terminated sessions never"  goes up from 0.
That was an indicator for an non-existing rtpengine_manage() or rtpengine_delete() at the end of dialogs. Okay.

Now I want to observe that a bit more.
I use parallel forking to webrtc clients, that i guess will be the "more Offers" than Answers.
Any hints on what numbers are important?
