Metric for people in oncall with no 'live' connectivy method

[KlavsKlavsen]

What would you like to see!

I would really like to be able to raise a metric for any user in an oncall schedule - that isn't currently connected with a "live connectivity metric" (such as telegram).

Since those users then won't actually see any messages from oncall - and we've seen this not being noticed by them (until alerts fly and escalations fire to someone else). So catching this when it breaks - instead of when it fails in oncall - would be really nice :)
