This dashboard was created in vROps 7.0 and uses two super metrics, both are included here. I've converted the OS Uptime metric, which is in seconds, to hours and days. I've used a 48 hour scale with anything under 24 hours showing as yellow or red, highlighting those VMs that have been recently rebooted. The super metrics (.json files) are available via my GitHub repo: https://github.com/brockpeterson/vrops_dashboards.
Once downloaded, import the super metrics via the Administration tab as shown here:
Once imported, you will need to enable these super metrics in the Default Policy via the Policies tab:
Edit the Policy via the pencil icon and enable the new super metrics:
The dashboard will look like this:
uptime_in_days supermetric - uptime_in_days_supermetric.json
uptime_in_hours_supermetric - uptime_in_hours_supermetric.json
