Events are exported by the OpenSIPS core through the Event Interface.


Threshold limit exceeded

Event: E_CORE_THRESHOLD

This event is triggered when a particular action takes longer than a specific threshold. It can be raised when a MySQL or DNS query takes too long, or a SIP message processing goes beyond a specific limit. For more information please see this post.

Parameters:

  • source: the source of the event: mysql module, core (for DNS or message processing warnings).
  • time: the number of micro-seconds the limit has been exceeded
  • extra: extra information, depending on the source of the event

Private memory threshold exceeded

Event: E_CORE_PKG_THRESHOLD

This event is triggered when the private memory usage goes above a threshold limit, specified by the event_pkg_threshold the core parameter. It warns external applications about low values of free private memory.

Parameters:

  • usage: the percentage of private memory usage. Can have values between event_pkg_threshold and 100.
  • threshold: the event_pkg_threshold specified in the script.
  • used: the amount of private memory used.
  • size: the total amount of private memory.
  • pid: the pid of the process that raises the event.

Note: If the event_pkg_threshold is not specified or 0, then this event is disabled.

Shared memory threshold exceeded

Event: E_CORE_SHM_THRESHOLD

This event is triggered when the shared memory usage goes above a threshold limit, specified by the event_shm_threshold the core parameter. It warns external applications about low values of free shared memory.

Parameters:

  • usage: the percentage of private memory usage. Can have values between event_shm_threshold and 100.
  • threshold: the event_shm_threshold specified in the script.
  • used: the amount of private memory used.
  • size: the total amount of private memory.

Note: If the event_shm_threshold is not specified or 0, then this event is disabled.
