How to troubleshoot when having error 'No data available' for System Uptime?

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 - uptime|cut -d ',' -f1,2|tr -s ' ' '^'|cut -d '^' -f 2-
Linux - uptime|cut -d ',' -f1,2|tr -s ' ' '^'|cut -d '^' -f 2-
FreeBSD - uptime|cut -d ',' -f1,2|tr -s ' ' '^'|cut -d '^' -f 2-
Macos - uptime|cut -d ',' -f1,2|tr -s ' ' '^'|cut -d '^' -f 2-
Sun - uptime|cut -d ',' -f1,2|tr -s ' ' '^'|cut -d '^' -f 2-
