Is it intended to actually send an e-mail every 3 minutes, or is it doing that because it found a problem? In my case, it's detecting some device as being offline, and another drive with 202GB free:
SELECT PK_Device, Description FROM Device WHERE FK_DeviceTemplate IN (1790, 1769, 1768, 1854, 1851, 1849)
1 02/26/08 11:24:01 DiskSpaceMonitor.sh (server) [1;00mFilesystem ( /mnt/device/29 ) is Offline [1;00m
1 02/26/08 11:24:01 DiskSpaceMonitor.sh (server) [1;00mFilesystem ( /mnt/device/30 ) has 202841 MB free [1;00m
