Normalise Plugin (Example)
This is an example plugin that demonstrates how plugins can be used to "normalise" alerts from different monitoring sources to ensure they conform to a standard before being saved to the database.
- two alert attributes are checked for values and if no value is set they are assigned default values.
- alert text is modified to prepend the severity level in capitals.
This repo should be forked or copied and the python plugin modified to suit the specific Alerta environment.
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/normalise
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.
normalise to the list of enabled
configuration file and set plugin-specific variables either in the
server configuration file or as environment variables.
PLUGINS = ['reject','normalise']
Restart Alerta API and confirm that the plugin has been loaded and enabled.
DEBUG=True in the
alertad.conf configuration file and look for log
entries similar to below:
