How to setup graph from 3am-11pm

Hello,

I have an ElasticSearch graph watching webservices where my current query is “NOT response_status:200”.

I am trying to check all the unavailability of those webservices, however between 11pm and 3am, there are several servers reboots happening which means that the webservices are unreachable and it is normal. I keep receiving alerts at these hours and I would like to stop receiving them.

Is there a way to configure, either through the Lucence query or the direct Alerts settings, a time range?

Basically I want to know if my webservices have problems only between 3am and 11pm, every day.

Thanks a lot!!
