[hobbit] Help with disk monitoring

Thanks for your quick response:) I did see that we have the big brother client installed so I need to plan on upgrading the clients first.

Thanks again

Ed

Also the file systems from these problem servers show up differently as well. The standard file system mounts are displayed without an issues but the LVM maps display the mount point but nothing else

/dev/mapper/sysvg-opt /dev/mapper/sysvg-var /dev/cciss/c0d0p1 2016016 216060 1697544 12% / /dev/cciss/c0d0p2 3020172 950024 1916728 34% /usr

This is a classical problem with the Big Brother client - you are apparently using the BB client instead of the Hobbit client. What's happening is that the "df" command used on the monitored servers breaks long lines in the output, so your "df" output looks like

Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda1 579598 192382 356293 36% / /dev/mapper/vg1-lv_usr 2568144 648964 1788724 27% /usr /dev/mapper/vg1-lv_var 1048540 733448 315092 70% /var

and since the BB client does a 'grep "^/dev"' to weed out entries like tmpfs, you only get the /dev/mapper line, not the next line with the actual data in it.

The solution is to change the DFCMD setting on your servers to "df -P", making it use the POSIX format output.
