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-A | 2021-08-01-16:20:00 |
| Instance-B | 2021-08-01-16:19:55 |
| Instance-C | 2021-11-27-4:19:59 |
| Instance-4 | 2021-08-01-16:20:00 |
| Instance-E | 2021-08-01-16:20:00 |
| Instance-… | Datetime of last data |
