Nomad Metrics to determine service uptime

Thought I might ask here and see how (if at all) teams are using Nomad metrics to calculate service uptime. We haven’t seen anything that stands out that we could use, but it’s quite possible we’re missing something obvious. It seems like Nomad should have all the pieces to determine this (if the job should be running, number of allocations and the health from consul thereof).

Curious, if any of you mind sharing - how do you calculate your service uptime today?
