Re: [Ganglia-general] very annoying issue with jittery cluster graphs

[Ian Cunningham]

John, I have problems similar to this which I blindly attribute to running my gmetad on a really slow server. If I were you, I would consider looking thru the archives for a tip on using tmpfs to store your rrds. While I have no proof this will fix your problem, my guess is it will. I also believe it is due to one of these two bugs: http://bugzilla.ganglia.info/cgi-bin/bugzilla/show_bug.cgi?id=76 http://bugzilla.ganglia.info/cgi-bin/bugzilla/show_bug.cgi?id=52 Ian john allspaw wrote: Hello there - I'm attaching two graphs from the grid view of my ganglia install, load and memory. The cluster has 24 nodes, and the individual nodes don't drop in or out as the graphs are showing, all of their individual graphs look normal. Anyone have any idea what's going on here ? -john
