How to troubleshoot when having error 'No data available' for process server?

Possible Scenario -  I get a "No data available" message for Inode Usage while trying to monitor servers.
Solution:
The connection must be established only through TELNET or SSH mode. 
Check whether the below command runs and displays corresponding output in the system.

Command to be executed on the server  =>

Novell - /bin/ps -eo fname,pcpu,pmem,command|cat
Linux - /bin/ps -eo fname,pcpu,pmem,command|cat;echo 'NUMBER_OF_PROCESSORS';cat /proc/cpuinfo|grep 'processor'|wc -l
FreeBSD - /bin/ps -axwwwwwwwwo comm,pcpu,pmem,command|cat
Macos - /bin/ps -axwwwwwwwwo ucomm,%cpu,%mem,command|cat
Sun         - /bin/ps -eo fname,pcpu,pmem,args
