Spotlight on Unix not displaying Disk Activity (4341805)

Spotlight on Unix is not displaying Disk Activity.

First make sure that the following UNIX programs are accessible to the user logged on to the UNIX machine (Spotlight user).

cat
date
df
iostat
grep
ifconfig
ps
sed
sar
netstat
uname
uptime
wc
who
vmstat
tr

If all of the commands can be accessed then try using SSH instead of REXEC to connect with Spotlight on Unix. Switching to SSH might solve the problem. Otherwise it has to investigated further and a support case needs to be created.
