alertmanager-notifier

A notifier for alertmanager, written in python. It supports multiple notification channels and new ones can be easily added.

Deprecation

Telegram Deprecation: Starting with the version 0.5.0 of alertmanager-notifier, Telegram support is dropped. As such, the documentation has been updated to reflect it.

Running a simple test

docker run --rm -it \
    -p 8899:8899 \

    -e GOTIFY_TOKEN="your gotify token" \
    -e EXCLUDE_LABELS="yes" \
    --name alertmanager-notifier \
    registry.gitlab.com/ix.ai/alertmanager-notifier:latest

Run the test agains the bot:

curl -X POST -d '{"externalURL": "http://foo.bar/", "receiver": "alertmanager-notifier-webhook", "alerts": [{"status":"Testing alertmanager-notifier", "labels":{}, "annotations":{}, "generatorURL": "http://foo.bar"}]}' -H "Content-Type: application/json" localhost:8899/alert

Gotify Priority

Gotify supports message priorities, that are also mapped to Android Importance (see gotify/android#18).

If you set the annotation priority to your alert, with a number as value, this will be passed through to gotify.

Note: Since alertmanager supports sending multiple alerts in one message, alertmanager-notifier will always use the highest priority value for gotify from the batch.

Templating

alertmanager-notifier supports jinja templating. take a look in the templates/ folder for examples for that. If you want to use your own template, mount it as a volume in docker and set the *_TEMPLATE environment variable. The mount path should be under /templates/ (for example /templates/my-amazing-template).
