Many service providers offer webhooks as a means to integrate their service into another system.

Nagios based monitoring frameworks organize alerting by associating contacts to host and service objects.

If you're running an Elasticsearch cluster you might want to keep track of the metrics it produces.

When it comes down to monitoring Nagios is still the weapon of choice for many.

What's in a name?
