Help me better understand our Alerts

Our Solarwinds team has set up Disk alerts  at Warning, High, and Critical Thresholds.

From what I am told, they should apply to all disk volumes. 

If I look at the Active Alerts,  and filter down to volumes and to Critical alerts, I get a listing of a number of active critical disk alerts.

If I run a simple report, asking for  all volumes running above the critical alert threshold of 95%, it returns me a listing  of all volumes currently running above our critical threshold of 95%,  but it is double the size of the Critical Active Alert data.

This tells me that all of my volumes must not be alerting. 

If I look at the ones that are not showing on the active alert list, I see that in the box  called:

Why does it not show  the Warning and Critical Alerts?

It's hard to tell you why an alert did not trigger without seeing the full alert details. If the issue was remedied before the required time frame to trigger then you may see the high point on a graph or the screen of the node, but no alert.

Also if you go to Settings -> Orion Thresholds and Polling (section on settings page) -> Orion Thresholds -> Disk Usage - You can set Warning and Critical Thresholds globally, and then alert off the condition of the volume being in Warning or Critical State. If you need a third or custom value you can use a custom property for that metric. Also, through the node management - edit - you can override the global threshold if you want to adjust per device type.
