Hi,

Is it possible to have a sensu check which has multiple destinations is only counted as down if _ALL_ of the destinations fail?

I’d like a check which all my other checks can depend on, which ensures the sensu server is online before sending alerts.

i.e to stop alert floods if it’s the internet connection on the sensu server which is broken, not all of the destinations it’s monitoring.

The ideal here would be to check some big sites - like [google.co.uk](http://google.co.uk), [bbc.co.uk](http://bbc.co.uk) etc but only mark that check as down if _ALL_ of them are down, not just one of them.

Is this possible? - anyone done such a thing before?

Thanks,

Ian

I would put that complexity into the check itself

Good point - I actually started thinking about a check which did something like check\_ping xx || check\_ping yy - with short timeouts.

Considering these two points, I’d recommend extending [check-ping.rb](https://github.com/sensu-plugins/sensu-plugins-network-checks/blob/master/bin/check-ping.rb) in sensu-plugins-http, possibly contributing the multiple host check back with a PR, if you’re satisfied how it works for you.
