opensips_exporter
This exporter exposes OpenSIPS metrics for consumption by Prometheus using the Unix socket provided by OpenSIPS. It uses the OpenSIPS Management Interface to gather these statistics.
Tested and developed against OpenSIPS versions 1.10 and 2.4, though this will probably work with all other versions as well.
Status
Active / maintained
This project is considered stable for use in production environments.
Examples and dashboard
A few examples are provided to give you a clue on how this would be setup on a Prometheus instance:
And because gathering the metrics is only half of the story there's a dashboard you can import into a Grafana installation which works wonders with this exporter. The dashboard is also available on the Grafana dashboard site.
A picture is worth a thousand words.
Note: the dashboard uses elements from the node exporter but can still be used without it.
Usage
Make sure $GOPATH/bin is in your $PATH.
Usage of opensips_exporter:
-path string
The path where metrics will be served (default "/metrics")
-addr string
Address on which the OpenSIPS exporter listens. (e.g. 127.0.0.1:9434) (default ":9434")
-socket string
Path to the socket file for OpenSIPS. (default "/var/run/ser-fg/ser.sock")

Processors
There are processors available per 'module' of OpenSIPS. The processors take the
statistics from the OpenSIPS socket and turn it into a Prometheus metric. You can
recognise a processor by the naming convention of the metrics.
For example theopensips_core_replies metric comes from the core module and its
processor can be found in ./processors/core_processor.
You can find out more about the available modules in the OpenSIPS documentation.
Filtering enabled processors
It is possible to select what processors you want metrics from. You can do this by
appending collect[] parameters to your request. If for example you only want to
get metrics about the core
and usrloc
module you can do this as follows:
curl localhost:9434/metrics?collect[]=core:&collect[]=usrloc:
Note: You have to append : to the module name for this to work.
Development
To work on opensips_exporter, get a recent Go, get a recent dep, and run:
go get -u github.com/VoIPGRID/opensips_exporter
While developing, make sure to run dep ensure often enough to keep
dependencies up-to-date.
The github.com/VoIPGRID/opensips_exporter/opensips package contains the
implementation of the interactions with OpenSIPS needed to get statistics from
the mi_datagram Unix socket of a running OpenSIPS. For tests, there is a mock
in the ./internal/mock package.
Metrics from different OpenSIPS modules are extracted by processors defined in
the ./processors package. To extend this exporter with metrics from other modules
create your own processor and implement the Collector interface. See the other
processors for inspiration.
