disk utilization graph

Hi,

Attached file is the disk utilization for a particular monitor. /data went up to 96% usage. However, we already did some housekeeping for the filesystem and it went down to 72% but I�ve noticed that the status of the filesystem is still on critical alert (red icon). Also, there is a root cause analysis:

Disk utilization � critical
Disk utilization of <servername>-/data is critical because its value 94>90%. Threshold details [critical alert if >90, warning alert if =80, clear alert if < 50]

Also, could you kindly check the other filesystems. I already configured them with alerts, however it seems that they are not recognized (unknown status) by the program. Thanks. :)
