This module provides a HTTP interface for the Prometheus monitoring system, allowing it to fetch different statistics from OpenSIPS.
In order to use it, you have to explicitely define the statistics you want to provide by listing them in the statistics parameter.
Currently only counter and gauge metrics types are supported by the module, and whether to choose one or the other for a specific statistic is dictated by the way that statistic was defined either internally, or explicitely through the variable parameter of the statistics module.
Each exported statistic comes with a group label that indicates the group it belongs to.
Specifies the root metrics path Promethus uses to query the stats: http://[opensips_IP]:[opensips_httpd_port]/[root]
The default value is "metrics".
Appends a prefix to each statistic exported.
The default value is "opensips".
Appends a prefix to the name of the group the statistic belongs to.
The default value is "" (no group prefix).
Specifies the delimiter to be used to separate prefix and group_prefix.
The default value is "_".
Specifies the label used to store the group when group_mode is 2.
The default value is "group".
Specifies how the group of the statistic should be provisioned to Prometheus. Available modes are:
0 - do not send the statistics groups.
1 - send the group in the name of the statstic.For example, timestamp statistic from the core group would be exported as opensips_core_timestamp. Note that the group_prefix is still attached to the group's name.
2 - send the group as a label of the statstic.The name of the label is specified by the group_label parameter.
The default value is 0 (do not specify the group).
The statistics that are being exported by OpenSIPS, separated by space. The list can also contain statistics groups's names - to do that, you shall add a colon (:) at the end of the groups's name.
If the all value is used, then the module will expose all available statistics - therefore any other settings of this parameter is useless;
This parameter can be defined multiple times.
The default value is empty: no metric is exported.
Example 1.7. Set
... # export the number of active dialogs and the load statistics class modparam("prometheus", "statistics", "active_dialogs load:") ...
In order to have Prometheus query OpenSIPS for statistics, you need to tell him where to get statistics from. To do that, you should define a scarpe job in Prometheus's scrape_configs config, indicating the IP and port you've configured the httpd module to listen on (default: 0.0.0.0:8888).
Example 1.8. Prometheus Scrape Config
scrape_configs: - job_name: opensips static_configs: - targets: ['localhost:8888']

(2) including any documentation-related commits, excluding merge commits. Regarding imported patches/code, we do our best to count the work on behalf of the proper owner, as per the "fix_authors" and "mod_renames" arrays in opensips/doc/build-contrib.sh. If you identify any patches/commits which do not get properly attributed to you, please submit a pull request which extends "fix_authors" and/or "mod_renames".
(3) ignoring whitespace edits, renamed files and auto-generated files
