There may be a workaround thought: if you use 'rrdtool dump', you will get a (large) XML file with all of the data. You should be able to then use 'rrdtool restore' to read this back into the new .rrd file. But since you probably have hundreds or thousands of rrd files, you need some automation.

A few years ago I had put a script on ganglia's bugzilla that modifies the rrd files to do a few simple things, like change the heartbeat value and change the number of RRAs, see: http://bugzilla.ganglia.info/cgi-bin/bugzilla/show_bug.cgi?id=33 Since we are in the process of moving our gmetad

This looks like a useful script. Can we add it to the contrib area in the Ganglia repository? Brad On 5/21/2008 at 9:51 AM, in message [EMAIL PROTECTED], Jason A. Smith [EMAIL PROTECTED] wrote: A few years ago I had put a script on ganglia's bugzilla that modifies the rrd files to do a few

I have a ganglia install running on a linux server (Ganglia version 3.03) and need to move it to a new Solaris 10 server (Running 3.0.9). I had assumed that if I just set up the server with the same overall config and copied all of my $Ganglia/rrds directory, this would allow me to preserve my

This could be a problem with rrdtool, and not Ganglia. I think that the .rrd file format is not compatible between 32bit and 64bit systems. Are you doing anything like that? If you are moving between 64bit hardware, are you sure that both are/were 64bit programs, and not 32bit binaries instead?

Great! I'll try that. Next silly question for the floor - I have a bunch of hosts that are showing up by IP address, even though the host knows about them by name (forward and reverse dns both work). Is there a way to fix this? On 5/20/08 8:34 PM, Jesse Becker [EMAIL PROTECTED] wrote: This
