The Status/Report (or SR) is an OpenSIPS framework that allows different components of OpenSIPS (like modules, parts of the core) to publish their status (in terms of readiness) and reports (logs) relevant to their activities.
This framework is intended to be used in operational activities, to check the readiness of OpenSIPS when starting up, to monitor its status at runtime and to trace back its operations via the logs/reports.

Overview

The base element in the Status/Report framework is the identifier - an status and some reports may be attached to an identifier. All the identifiers do exist within a Status/Report group. So, a group is a set of identifiers - a module or a core may be such groups. For example the drouting module publishes the drouting group where each routing partition is an identifier.
As there are cases where the group (the modules) do not need multiple identifiers, there is a default main identifier - such identifier may be referred only by the name of the group.

The information attached to an identifier is:

• status as integer value, translating if the identifier is ready for operation or not; a strict negative value means not-ready, while a strict positive value means it is ready; a zero value is not accepted.
• status details is a optional text to the status, providing some human friendly (or details) information in regards to the current status.
• reports is a fix-size array (rather a queue discarding the oldest records) of logs produced by the identifier. Each report/log is produced with a timestamp also.

I most of the cases, the status and reports of an identifier are internally produced by the OpenSIPS code - the Status/Report interface just gives you access to the status / report information from outside the code, for monitoring purposes.

Scripting functions

The SR Interface provides a script function to check the readiness status of an identifier (or of an entire group), see the sr_check_status( group, [identifier]) function.

MI functions

The SR Interface provides multiple functions to check/list the status of one/multiple identifiers and to list their reports:

• sr_get_status
• sr_list_status
• sr_list_reports
• sr_list_identifiers

Events

The SR framework raises an event each time the status of a Status/Report identifier changes. See the E_CORE_SR_STATUS_CHANGED event for more details.

Core identifiers

The OpenSIPS core provides the core group, with a "main" (default) identifier. The available status are:

• STATE_NONE (-100) - OpenSIPS just started
• STATE_TERMINATING (-2) - OpenSIPS is shutdown sequence
• STATE_INITIALIZING (-1) - OpenSIPS in startup sequence
• STATE_RUNNING (1) - OpenSIPS fully up and running

Modules identifiers

The OpenSIPS modules may or may not provide their own groups and identifiers. For this you need to check the module's documentation.

Scripting identifiers

The status_report allow the creation of custom SR identifiers from script level. Even more, it is possible to set the status or to publish a report from script for such custom identifiers.
