!!! Process Auto-Scaling (upscale and downscale)

'''Event''': E_CORE_PROC_AUTO_SCALE

This event is triggered whenever a new process is created (forked) or a process is terminated due the auto-scaling logic. In order to have this event trigger, the [[https://www.opensips.org/Documentation/Script-CoreParameters-3-6#auto_scaling_profile|auto-scaling]] must be enabled in your configuration.

!!! TCP connection disconnected

'''Event''': E_CORE_TCP_DISCONNECT

This event is triggered when a TCP connection is terminated/disconnected.

Parameters:

* '''src_port''': the source PORT of the TCP connection
* '''dst_ip''': the destination IP of the TCP connection
* '''dst_port''': the destination PORT of the TCP connection
* '''proto''': the protocol of the underlying TCP connection ( ie. tcp, tls, ws, wss, etc )

* '''proto''': the protocol of the underlying TCP connection ( ie. tcp, tls, ws, wss, etc )


!!! Process Auto-Scaling (upscale and downscale)

'''Event''': E_CORE_PROC_AUTO_SCALE

This event is triggered whenever a new process is created (forked) or a process is terminated due the auto-scaling logic. In order to have this event trigger, the [[https://www.opensips.org/Documentation/Script-CoreParameters-3-6#auto_scaling_profile|auto-scaling]] must be enabled in your configuration.

Parameters:
* '''group_type''': the type/name of the scaling group (UDP/TCP/TIMER).
* '''group_filter''': the filter (usually the socket/interface for UDP) of the scaling group.
* '''group_load''': the load over the scaling group.
* '''scale''': "up" or "down"

!!! 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 [[http://lists.opensips.org/pipermail/users/2011-February/016918.html | 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.

>>important<<
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.

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