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. opensips-cli -x mi get_statistics load: core: shmem:)

2.  "LOAD" class

Statistics giving information about the OpenSIPS internal load. The load is defined as percentage of time spent in doing processing versus total time. Following the model of "top", there are three load values, calculated over different periods of time:

• realtime load - calculated over the last 1 second
• last minute load - calculated over the last 1 minute
• last 10 minutes load - calculated over the last 10 minutes

All three load values are provided by OpenSIPS in a per-process manner (the load of each process) and globally (covering all processes).

2.1 load ¶

The realtime load of entire OpenSIPS - this counts all the core processes of OpenSIPS; the additional processes requested by modules are not counted in this load. Also note that some core processes are not counted as they do not generate any kind of load; such processes are the attendant, the time keeper and the timer trigger. This statistic is actually reflecting the load generated by processing the SIP traffic (as only the core active processes are counted).

Example of usage through MI FIFO

opensips-cli -x mi get_statistics load
load:load:: 24

Example of usage from script

xlog("The OpenSIPS processing load is $stat(load) \n");

2.2 load1m ¶

The last minute average load of core OpenSIPS (covering only core/SIP processes). For more, see load.

2.3 load10m ¶

The last 10 minutes average load of core OpenSIPS (covering only core/SIP processes). For more, see load.

2.4 load-all ¶

The realtime load of entire OpenSIPS, counting both core and module processes. Similar to [[#load|load], the processes not generating load at all are not counted.

Example of usage through MI FIFO

opensips-cli -x mi get_statistics load-all
load:load-all:: 24

Example of usage from script

xlog("The overall OpenSIPS load is $stat(load-all) \n");

2.5 load1m-all ¶

The last minute average load of entire OpenSIPS (covering all processes). For more, see load-all.

2.6 load10m-all ¶

The last 10 minutes average load of entire OpenSIPS (covering all processes). For more, see load-all.

2.7 load-proc-id ¶

The realtime load of the process ID. To learn the IDs of the OpenSIPS processes (and their types), use the ps MI command.

Example of usage through MI FIFO

opensips-cli -x mi get_statistics load-proc-5
load:load-proc-5:: 79

Example of usage from script

xlog("The load of processes 5 is $stat(load-proc-5) \n");

2.8 load1m-proc-id ¶

The last minute average load of the process ID. For more, see load-proc-id.

2.9 load10m-proc-id ¶

The last 10 minutes average load of the process ID. For more, see load-proc-id.
