How to monitor health of influxdb and be notified if

I’m trying to figure out how to monitor uptime of InfluxDB in Chronograf and send notification if the uptime is less than 1 hour for example.
All I know is this query SHOW DIAGNOSTICS FOR 'system' to retrieve uptime but I have no idea how to extract only the uptime field so I can act accordingly

name: system
PID currentTime                   started                        uptime
--- -----------                   -------                        ------

To be clear, you are trying to monitor the health of InfluxDB OSS v2?

Have you looked at the pre-built template that would help you?

There are instructions on how to configure this. This is a starting point, but I think once you have this setup, you should be able to understand how to create a check and notification rule to do what you want.
