We're building a full-text search index, and I guess that causes high CPU usage on the cluster. So I've been getting alerts pretty much every few minutes for about 16 hours. I went to "acknowledge" the alert, but since it's flapping, the acknowledgement gets removed when the CPU recovers, and then a new alert is generated a few minutes later.

I would like to be able to disable alerts during search index builds so that I am not spammed with emails.
