Zenoss 3 adding custom properties

In version 3.X... click Infrastructure at the top navigation, then click IP Services on the submenu. On the left use the search field to find SMTP. In the right side pane under "enable monitoring (zMonitor)" change the value to no.

remodel the device immediately and see if it stops monitoring smtp. you may have to restart the collector.

The default Windows device class in ZenOSS has two requirements. First, enable SNMP and make sure that you've set the community strings correctly. Second, install the free SNMP informant module on the server you're trying to monitor, which Zenoss uses to collect more reliable statistics via SNMP.

Now, you also mentioned you installed the WMI performance zenpack, which will require you to move the device into a device configured for WMI modeling and performance collection.

You shold not have have to be defining datapoints or graphs at this stage, the built-in templates should be providing these for you.
