.. _prometheus:
Prometheus
==========
You can export statistics to a ``Prometheus`` server through an exporter.
When the *--export-prometheus* is used, Glances creates a Prometheus exporter
listening on <host:port> (define in the Glances configuration file).
.. code-block:: ini
[prometheus]
host=localhost
port=9091
prefix=glances
labels=src:glances
.. note::
When running Glances in a container, set ``host=0.0.0.0`` in the Glances configuration file.
.. note::
You can use dynamic fields for the label (ex: labels=system:`uname -s`)
and run Glances with:
.. code-block:: console
$ glances --export prometheus
You can check that Glances exports the stats using this URL: http://localhost:9091

In order to store the metrics in a Prometheus server, you should add this
exporter to your Prometheus server configuration with the following lines
(in the prometheus.yml configuration file):
.. code-block:: ini
scrape_configs:
- job_name: 'glances_exporter'
scrape_interval: 5s
static_configs:
- targets: ['localhost:9091']
