This application bridges [Prometheus Alertmanager](https://prometheus.io/docs/alerting/latest/alertmanager/) alerts to [Gotify](https://gotify.net/).

# Usage
```
usage: alertify.py [-h] [-c CONFIG] [-H]

Bridge between Prometheus Alertmanager and Gotify

optional arguments:
  -h, --help            show this help message and exit
  -c CONFIG, --config CONFIG
                        path to config YAML. (default: alertify.yaml)
  -H, --healthcheck     simply exit with 0 for healthy or 1 when unhealthy

The following environment variables will override any config or default:
  * DELETE_ONRESOLVE  (default: False)
  * DISABLE_RESOLVED  (default: False)
  * GOTIFY_KEY_APP    (default: None)
  * GOTIFY_KEY_CLIENT (default: None)
  * GOTIFY_PORT       (default: 80)
  * GOTIFY_SERVER     (default: localhost)
  * LISTEN_PORT       (default: 8080)
  * VERBOSE           (default: 0)
```


# Notes
* Listens on port 8080 by default.
* Forwards `resolved` alerts, if not disabled.
* Resolved alerts delete the original alert, if enabled.
* Requires a Gotify app key to send alerts to Gotify
* Requires a Gotify client key to delete original alert on resolution
* Defaults, if not sent:
  | Field       | Default value |
  |-------------|---------------|
  | Priority    | `5`           |
