[mrtg] Re: Disk I/O stats

[Bjorn Nilsen]

This is the output from my awk command, is there a problem that the two
numbers are the same and I have left the uptime and hostname blank?

# /usr/bin/awk '/cpu /{print $2+$3+$4+$5; print $2+$3+$4+$5; print ""; print
""}'</proc/stat
1094155649
1094155649


# /usr/bin/awk '/cpu /{print $2+$3+$4+$5; print $2+$3+$4+$5; print ""; print
""}'</proc/stat
1094156076
1094156076


# /usr/bin/awk '/cpu /{print $2+$3+$4+$5; print $2+$3+$4+$5; print ""; print
""}'</proc/stat
1094156180
1094156180
