Does it represent an average or is it the sums of all the hosts? For instance
CPU usage the other day got as high as 250% on the summary info but the hosts
never top 100%...
Is it me? Although Ganglia handles the RRDs I have a program for graphing them
myself and wondering if something like:
RRDs::graph ("$snapshot",
"--sta...@{[int($begin/$rrdres)*$rrdres]}",
"--e...@{[int($end/$rrdres)*$rrdres]}",
"--step=$rrdres",
"--lower-limit=0",
"--upper-limit=$ymax",
"--vertical-label=$metric",
"DEF:var=$rrdpath:sum:AVERAGE",
"LINE2:var#FF0000");
Is a bad idea for a __SummaryInfo__?
Thanks again in advance
