Ideally, I'd like to see the name of the server group ("prod" in the example) change to blue from white on the main view to remind me there's an ignored test. But I don't want the "main view" colour to change from green
Don't disable the test. Acknowledge the alert.
Let me explain the situation a little more clearly.
We have tons of servers deployed in pairs. Each pair consists of an active box and a standby box and it doesn't technically matter which one of the two is active. For consistency reasons, we like to keep it so the "first" box is active whenever possible.
If the first box fails over, for whatever reason, it generates a red alarm on Xymon saying it's no longer active and (after checking everything out) we ask someone on the night-shift to fail back over during off-hours. At this point, we don't want the main Xymon view to be red so we "ignore" the test. However, since the main view is now green, the techs sometimes forget that there's anything to do and it remains failed over until someone drills down and sees it.
I was trying to get to a state where they would know that there's a disabled/ignored/ack'd box from the front page to eliminate the "I missed the email" excuses
