davyjones

davyjones is a simple webhook receiver for Prometheus Alertmanager to send notifications to a ntfy instance for calling the kraken mobile push notifications.

In addition to translating alerts davyjones also comes with the ability to configure dead man switches, which can be used to send notifications when a "watchdog" alert hasn't been triggered for a certain amount of time.

Warning

davyjones is in a very early state and subject to changes. Please don't expect a finished software product. If you want to use it I welcome issues and pull requests, but I cannot guarantee this project is secure or works correctly.

Features

• Basic webhook support for processing Alertmanager webhook calls.
• Watchdog support for sending alerts if no Alertmanager webhook calls came in for a while.

For feature requests, please open a GitHub issue.

Usage

davyjones can either be built from source or be used from a container image hosted on GitHub Packages. The container image can be used with Docker, Podman or Kubernetes.

By default, davyjones binds to localhost. You might have to tweak that with the --host flag. davyjones does not support basic authentication right now, so it is recommended to deploy it behind a reverse proxy that secures access.

Usage: davyjones [OPTIONS]

Options:
  -v, --verbose          Enable verbose (debug) logging
  -c, --config <config>  Configuration file to start davyjones with
  -p, --port <port>      Port to listen on when starting webhook server [default: 8080]
      --host <host>      Host to listen on when starting webhook server [default: localhost]
  -h, --help             Print help

Configuration

davyjones is configured via a configuration file in TOML. An example can be found here.

Alertmanager

davyjones exposes an endpoint (/v1/webhooks/alerts) for Alertmanager. To configure Alertmanager, add a new receiver to your Alertmanager configuration file. davyjones requires a webhook_config, like this:

- name: davyjones
  webhook_configs:
  - send_resolved: true
    http_config:
      # only if you run davyjones behind a reverse proxy with basic auth
      basic_auth:
        username: <username>
        password: <secret>
    url: https://<your davyjones hostname>/v1/webhooks/alerts
