[asterisk-users] Troubleshooting load issues

[Telium Technical Support]

Could some calls be arriving with a different codec?  (Is transcoding causing the spikes)?  Are you limiting codecs to match your audio files?

Hi,

 

I have an Asterisk box which has an IVR that plays random gsm files. The box has SSD's and two CPU E5-2695 v2 cpus with 64GB ram. The Asterisk CPU usage along with the load seems to jump around. With about 500 callers it hovers between 250-400% CPU (so 2.5 to 4 cores) which seems reasonable. Every so often the load average spikes. The idle never drops below 85%. When the load average spikes I see a lot of kworker threads and the CPU usage tends to (not not always) go up as well. How would I go about seeing what in Asterisk is causing the spike? The box is locked down and only takes calls from an OpenSiPS box. There is nothing else running on the box.

 

TIA.

 

Dovid
