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

1.  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 amount of time (in microseconds) spent by the operation
• extra: extra information, depending on the source of the event

2.  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.

3.  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.

4.  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 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"
• process_id: the process ID (at OpenSIPS level) of the scaled (up or down) process.
• pid: the PID (OS level) of the scaled (up or down) process.

5.  TCP connection disconnected 🔗

Event: E_CORE_TCP_DISCONNECT

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

Parameters:

• src_ip: the source IP of the TCP connection
• 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 )

6.  Status/Report status changed 🔗

Event: E_CORE_SR_STATUS_CHANGED

This event is triggered the status of an SR identifier changes.

Parameters:

• group: the name of the SR group
• identifier: the name of the SR identifier
• status: the new status (as numerical value) of the SR identifier
• details: the details/text attached to the new status
• old_status: the old status (as numerical value) of the SR identifier

7.  Log message produced 🔗

Event: E_CORE_LOG

This event is triggered whenever a log message is produced by OpenSIPS. In order to have this event trigger, the log_event_enabled must be enabled in your configuration.

Parameters:

• time: time when the log message was produced
• pid: the PID of the processes that produced this log message
• level: the log level of this message ("DBG", "INFO" etc.)
• module: module that produced this log message; NULL for logs triggered from the script by the xlog() function
• function: internal function that produced this log message; NULL for logs triggered from the script by the xlog() function
• prefix: logging prefix, configured via the log_prefix parameter. It is an empty string if the parameter is not configured.
• message: the actual log message content
