Capturing grafana dashboard and post it to LINE group using LINE Notify

I want to post a screenshot of the Grafana dashboard to LINE Notify.

Grafana distribution includes PhantomJS( Alerting feature uses PhantomJS. https://github.com/grafana/grafana/blob/master/pkg/services/alerting/notifier.go#L96 ).

Then, you can take a snapshot using curl command.

You need to rewrite Grafana dashboard URL. Insert /render prefix for your dashboard URL. For example, when your dashboard URL is http://grafana.example.com/dashboard/db/my-service, PhantomJS URL is http://grafana.example.com/render/dashboard/db/my-service.

If you want to hide a header, add ?kiosk query parameter for the URL.

Grafana supports API keys and Basic Auth. With curl, you can call it like e.g. curl -u 'YOUR_EMAIL:YOUR_PASSWORD' GRAFANA_URL.

It's summarized as follows:

curl  -u 'YOUR_EMAIL:YOUR_PASSWORD' http://grafana.example.com/render/dashboard/db/my-service?kiosk -o img.png

Post to LINE Notify

You can upload dashboard image to LINE Notify using curl command.

curl -X POST https://notify-api.line.me/api/notify 
       -H 'Authorization: Bearer YOUR_PERSONAL_ACCESS_TOKEN' 
       -F 'message=test' 
       -F 'imageFile=@img.jpg'
