Grafana SMS alert

Send Grafana alerts via SMS to a mobile phone, using a GSM modem that understands AT commands, such as the Huawei E3131 broadband USB dongle. Fancy SaaS alerting services are great, but what if you want to know that the internet is down?

This runs as a service on localhost:8201 - once you've started it, create a "Webhook" type contact point in your Grafana instance, with the url http://localhost:8201.

See Grafana alerting contact points documentation for background.

Building and use (Nix)

Try it quickly

$ nix-build build.nix
$ cp config.json.example config.json # and edit it
$ ./result/bin/grafana-sms-alert config.json

$ curl -v --data @sample-alert.json http://localhost:8201

Install it meaningfully

The derivation in default.nix works with callPackage, so see module-example.nix for a sketch.
