What I see on the report page seems to be wrong!
As you can see the disk usage is said to be >80% and >90%


But in the graph, I see everything to be normal.



In fact, when I run "df -h", the disk usage is fine.

# df -h

I don't use the template you appear to be using, but I think you're mis-reading what the report is saying.

In the availability report you show, the "OK" column with 100% means that the trigger has not evaluated to a problem condition at any time during the reporting timeframe. The "/: Disk space is low (>80% used)" is only true when the trigger evaluates to a problem. As long as "OK" shows "100%", it means none of the configured triggers have detected any problems.
