Wayne,

This is a somewhat confusing aspect of Zenoss, and it's going to get a whole lot easier in the next release. I'll try my best to explain it...

Zenoss has the concept of "Device Classes". Those are the hierarchical paths you see like /Server/Linux and /Printer/ HPLaserJet4000.

A "Device Class (/Printer/HPLaserJet4000)" has a set of "Performance Templates" associated with it. The Performance Templates define what information zenoss should collect from devices that are placed into the Device Class associated with the performance template. Within the Performance Template there is a special "Device" section that people often confuse with the /Devices list. Think of the "Device" within the "Performance Template" as defining the host-level information.

Performance Templates are inherited from the Device Class hierarchy. If you don't create a Performance Template at the /Printer/ HPLaserJet4000 level you're going to get the Performance Template from /, which is labeled as /Devices.

Hope this helps.  It's very confusing...

I created a new class for HP 4000 series printers under /Devices/ Printers and added a performance template named hplj4000. The performance template definition path is /Devices/Printer/HPLaserJet4000. Myhplj4000 performance template has a single datasource that queries for total page count, and a graph to show the total page count.

When I add a device into the new class, I would have expected that the PerfConf tab would show the RRDTemplate to be /Devices/Printer/ HPLaserJet4000 but it always shows /Devices. My custom hplj4000 performance template is not listed.

Why is the RRDTemplate for all devices in the class /Devices/ Printer/HPLaserJet4000 not set to /Devices/Printer/HPLaserJet4000? How do I set it correctly?

Thanks
Wayne
