Well, I'm just getting back from Holiday break. Anyway - Zenoss stores it's perf data in subdirectories set by the name in Zenoss as far as I can tell, so if your data doesn't end up in the proper subdirectory, it doesn't graph I would guess. Zenoss doesn't use IP for the "primary key" (as it's partially a ZopeDB and partially a filesystem, I'm not really sure RMDB terms even are relevant).
So - you need things to be associated with the name in Zenoss. There are a number of forum posts, normally associated with changing the name of the Zenoss server itself (like your issue I think) that discuss this, and as far as I can tell, you can't "change" a device name in Zenoss - in fact you generally have to delete and re-create it with a new name. -- James Pulver Information Technology Area Supervisor LEPP Computer Group Cornell University max_bld wrote, On 12/26/2008 7:59 AM: > Hi all, > > On Tue Dec 23, 2008 2:32 pm I posted a topic "Temperature graph not working", > where I described how I was unsuccessfully trying to add a graph showing the > CPU temperature on my local linux box, the same in which the Zenoss daemons > are running. > > Actually, after install, I made Zennoss recognize my system on > /Devices/Server/localhost, being connected to it aiming the browser to the > URL http://localhost:8080/zport/dmd.
