Newbie Question about OMSA

[King Menus]

The Windows version of OMSA provides a built-in, fully configured GUI 
for monitoring hardware, but the Linux version appears to only provide 
the drivers, NIBS, etc. ?

I have successfully installed OMSA via YUM, but now what? Do I have to 
download and configure a separate tool to do the monitoring? (e.g. 
Nagios, etc.)

If so, any recommendations for a newbie?

Thanks in advance,
Ronnie
