Core Statistics v1.8

Prev

The OpenSIPS core exports several statistics, which are grouped into classes. To view all statistics which correspond to a class, fetch the "class:" statistic (e.g. opensipsctl fifo get_statistic load: core: shmem:)

2.  "LOAD" class

If OpenSIPS has two listen directives :
listen=udp:192.168.2.134:5060
listen=udp:192.168.10.13:5090

Then there will be two exported statistics, udp:192.168.2.134:5060-load and udp:192.168.10.13:5090-load, and each 
will show the percentage of working children on the respective interfaces.

opensipsctl fifo get_statistics udp:192.168.2.134:5060-load

Example of usage from script

xlog("The UDP load on 192.168.2.134:5060 is $stat(udp:192.168.2.134:5060-load) \n");

---

3.  "NET" class
