New version.
More bug fixes. There were some brown paper bag bugs in 
the Getopt::Long usage :(
Now it only checks for (a) the OS is in the supported_os 
hash, and (b) if it's linux, then parse it otherwise than the 
others (that is - it defaults to solaris/hpsux sar output format.

Uploaded new version with hpux support added.
Does anyone know if AIX or other unix flavours have the same 
output? BSD?

Though you like to know that HP-UX 11 sar command has the 
same output as solaris and by doing this the script works on
HP-UX 11, not sure about older versions.


added hpux to %supported_os and cut' paste line 87 - 94 and 
change solaris to hpux.

Last update includes adding 'licenced under GPL', so this can hopefully 
be included with the nagios plugins some time ...

Can you send me the output from this on your solaris box?

perl -e 'print "$^O\n"'

Its your script so you should rewrite it if you want to. This is 
how i changed it , and below is what sar 1 3 gives in Solaris 
(its the same for OS versions 2.6, 7 , and 8).

        if (/^Average/) {
                @values = split(/\s+/);
                $user = $values[1];
                $system = $values[2];
                $iowait = $values[3];
                $idle = $values[4];
                $stop = 1;
	}

What if you rewrite it to support Solaris?
Then we can do an OS check before running sar.

If you remove : in if (/^Average:/) { it will work in Solaris too.
