Dave, you may need to be more precise about what you want to happen.
If you are adding hosts to an existing cluster, simply give them the same configuration as the others and all will be fine. By fine I mean that the new hosts will appear in the cluster view, even if their data history is not as long as the others. But suppose you drop a host out of a cluster. The cluster view is created ONLY from the output of gmetad, which contains a snapshot at the current time only. The dropped host will disappear, and even if you ask for a year's worth of data to be shown (times when the host used to appear), it will not suddenly appear again. Also the host's rrd files will remain under the clustername in your rrd tree, and are never removed. And moving a host from one cluster to another. Do you move the host rrd's? Do you not? Ha ha. And the effect on the rollup cluster views when the above is done? Extra ha ha. kind regards, richard > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On > Behalf Of David Peterson > Sent: 24 October 2006 08:41 > To: [email protected] > Subject: Re: [Ganglia-general] Cluster under Grid issues > > > > That's a fine document.
