I'm currently exploring Watcher and I very much like the idea of having triggers and actions. But I fail to see any really good use cases.
One often used example is sending an email when there are errors in de indexed application logging. But I could also set up a Kibana dashboard for that. Yes, I know this is only a good alternative during business hours.
For every possible use case for Watcher I come up with, I see a good alternative solution. So I was wondering if there are others with very Watcher use cases to inspire me to use Watcher in ways I good never image.
Just post your ideas about using Watcher and inspire the rest of us.
