Grafana v8.0.3 (cae5c5e46b) with Prometheus (not sure which version)
I am trying to create a dashboard table that shows when the last data came from an instance. This is to spot hosts that have gone offline, or missed some arbitrary check-in time frame. The table doesn’t need to be a live view and could use a rollup of 5 minutes or an hour if needed. I am new to Grafana and Prometheus, but have used other monitoring platforms before, such as Splunk and Zabbix.
I have an example of what I want to make:
Current time in exmple 2021-08-01-16:24:20 (ish)
|Instance||Timestamp of last data from the instance|
|Instance-…||Datetime of last data|
