I am receiving an error message every couple of minutes.
Message: The threshold Memory in template /zport/dmd/Devices/Server/Windows/1%20Processor/rrdTemplates/Device has caused an exception.
How do I overcome this issue?
Are the graphs actually working? I believe this thread has revelant info to your issue: http://community.zenoss.org/docs/DOC-3386#comment-5020
You might be able to disable the threshold on the template to make the errors cease
The graphs were not working. I removed this zenpack. Was it not working because of this:
External Dependencies: It consists of 2 bash scripts which collect the information from the SNMP Service. The bash scripts rely on the 'bc' and 'snmpwalk' commands, so make sure that you have those installed on your server before using this ZenPack.
Where do I get these scripts and how do I install them?
The scripts will be included in the ZenPack, the bc and snmpwalk are likely already present, but you'll have to check as I don't know what distro you are using.
If you have removed the zenpack, the errors should have stopped, is that not the case?
In any case, I know alot of people use the pack, so if the graphs were not working that would explain the error message. You could potentially re-install the pack, and from there debug why the graphs were not working.
Yeah, you'll want to wait at least three polling intervals (usually 15 minutes) before the NANs should be replace with actual data. If your still seeing NANs after that something is up that will require some additional debugging
The error I am receiving is

I tried to snmp walk one of the errors and I got this
