Prometheus Alertmanager Plugin

Two-way integration with Prometheus which will silence alerts in Alertmanager when alerts are ack'ed in the Alerta console and delete silences if those alerts are manually re-opened.

Clone the GitHub repo and run:

$ python setup.py install

Or, to install remotely from GitHub run:

$ pip install git+https://github.com/alerta/alerta-contrib.git#subdirectory=plugins/prometheus

Note: If Alerta is installed in a python virtual environment then plugins need to be installed into the same environment for Alerta to dynamically discover them.


Add prometheus to the list of enabled PLUGINS in alertad.conf server configuration file and set plugin-specific variables either in the server configuration file or as environment variables.

PLUGINS = ['prometheus']

The below settings are configured with reasonable defaults:

ALERTMANAGER_API_URL = 'http://localhost:9093'

Robust Perception Demo Example

PLUGINS = ['reject','prometheus']
ALERTMANAGER_API_URL = 'http://demo.robustperception.io:9093'  # default=http://localhost:9093


Restart Alerta API and confirm that the plugin has been loaded and enabled.

Set DEBUG=True in the alertad.conf configuration file and look for log entries similar to below:
