Meaning: A File System Resource space is 80-85% utilized. While not critical, the space usage should be monitored. The index value of the alarm indicates the file system index that may be looked up in the fileSystem table 'fileSystemSpace' for more information about the actual FS that is getting full. What to do: no action is necessary, but the file system should be monitored more closely as it grows more full. Further alarms will be sent when and if the file system space is approaching very full.
