[mrtg] Re: graphing CPU usage on my Linux BOX (HELP)

[Paul C. Williamson]

There is at least one problem here, easily fixed...

If you specify anything other than Workdir, you need to specify 
everything, but omit the Workdir.

Prepending the Options[^]: growright doesn't make any difference since 
you are specifying it in the last line.  The prepending is (IMHO) best 
applied for html page formatting, but not really good for the graphs.

Are you doing this on a machine local to mrtg?  If so, why not just use 
the external program interface and do what Alex has demonstrated on 
the faq?  It's a one-liner:

`/usr/bin/awk '/cpu /{print $2+$3; print $2+$3+$4; print "long time"; print "home"}'</proc/stat`

Note that I don't think this will work with 2.9.17 because of the "long time" 
and "home" values.  I think these need to be the actual uptime of the box and the hostname of the machine now.

Hi,

Im trying to graph my CPU usage in my linux box. When I try to run the 
command ./mrtg cpu.cfg im getting an error message
		WARNING: "Title [cpu-util]" is not specified
		WARNING: "PageTop [cpu-util]" is not specified
		WARNING: "MaxBytes [cpu-util]" is not specified
		ERROR: Please fix the error(s) in your config file.

Any inputs would be highly appreciated.
