We have the following use case.
Lets say we have a web server cluster A with 2 servers all checked by Sensu.
If a web server goes down it will show it in the Sensu API for this particular web server. If another one goes down it will also shown in the Sensu API.
But what we additionally want is that we get a third event saying that the cluster A is completely down now.
What would be the best approach to archive this?
Thanks in advance!
