alerta-blackout-regex ===================== `Alerta <https://alerta.io/>`_ plugin to enhance the blackout management, by matching the alerts against blackouts with PCRE (Perl Compatible Regular Expression) on attributes. A blackout is considered matched when all its attributes are matched. Once an alert is identified as matching a blackout, a special label is applied, with the format: ``regex_blackout=<blackout id>``, where *blackout id* is the ID of the matched blackout, e.g., ``regex_blackout=d8ba1d3b-dbfd-4677-ab00-e7f8469d7ad3``. This way, when the alert is fired again, there's no need to verify the matching again, but simply verify whether the blackout referenced is still active. .. important:: Beginning with version 2.0.0, the behaviour has changed, and instead of evaluating the alert into the `post_receive` hook, this plugin now evaluates the alerts through the `pre_receive` hook. The reasoning was that `post_receive` would set the `blackout` status *after* the alert has been sent to other plugins, which has resulted in confusing behaviour. That said, the plugin has been changed to process the alert in ``pre_receive`` and therefore before the alert has been correlated. As the Blackouts are retrieved from the Alerta API as unfortunately there's no other way to gather the Blackouts from a plugin via other internal mechanisms, processing each and every alert throguh `pre_receive` would put a lot more workload on your Alerta API. To reduce this, the `blackout_regex` plugin now caches the Blackouts locally, into a file. To fine tune this behaviour for your own setuo you are able to set a few environment variables. See more details below, under the _Configuration_ section. .. note:: Starting with version 3.0.0 onwards, the plugin will gather the list of Blackouts straight from the database (instead of using the API, as previously). This should normally improve reliability, but as there's no caching involved, every alert notification coming in (before being evaluated and correlated) will cause a DB query. Installation ------------ This plugin is designed to be installed on the Alerta server; the package is available on PyPI so you can install as: .. code-block:: bash pip install alerta-blackout-regex Configuration ------------- Add ``blackout_regex`` 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. .. code-block:: ini PLUGINS = ['blackout_regex'] .. note:: To ensure this plugin won't affect the existing Blackouts you may have in place, it is recommended to list the `blackout_regex` plugin *after* the native ``blackout`` plugin in the ``PLUGINS`` configuration option or environment variable.
