Same hostname too I presume? On gmetad, your hosts show up with hostnames, correct? > Telnet from the master to the new host gives an XML document, same as > the old one. What I would test is telnet (or nc) from master to _another_ host and make sure that it has metrics from the "new" host.

Just FYI, the recommended combination should be: 1) stop gmetad 2) stop all gmond 3) start all gmond 4) start gmetad > Is there some known procedure for replacing a Ganglia-monitored host? > Do I have to remove > the old one's rrd files or something? Is this documented anywhere? You shouldn't have to. Curious if there are any errors in your httpd logs? Also, I assume you're not having time synchronization issues?
