Subject: | WMI or SNMP on Windows servers? |

Hey guys,
I've heard that WMI uses some system resources on the server compared to SNMP that is a bit leaner. It could also lead to potential problems due to memory leaks is worst cases. Is SNMP to prefer over WMI when monitoring Windows servers
Thanks,

Neither is preferred. Microsoft is completely dropping SNMP support, and WMI is going to be obsoleted as well. WinRM/WinRS are the replacement and our newest microsoft windows ZenPack leverages these to monitor windows.

Excellent, I'm glad I asked then. And thanks a lot for your answer Andrew.

Hi guys,
We're actually considering using SNMP instead of WinRM for monitoring Windows hosts. This due to the fact that setting up WinRM (encrypted) on the windows side was a lot of manual work.
Now I am fully aware that SNMP 2c is not encrypted either, but as a step in between we're considering using http://www.snmp-informant.com/snmp_informant-standard.htm on the Windows side.
Let me know if you think this is total madness or not.
Now, there seem to be 3-ish ways to do SNMP monitoring in Zenoss
Using net-snmp
Using Windows own SNMP-service
Using http://www.snmp-informant.com/snmp_informant-standard.htm AND Windows own SNMP service
Which of these ways are the recommended procedure and co-exists best with the "Nova" SNMP ZenPack If there is a good document describing this, please feel free to quote or point me in the right direction. Cos honestly I find a lot of different ways to do this, and it's rather confusing...
Cheers,
/Stefan

If you're going to use SNMP you definitely want the free Informant on your servers - otherwise you get no aggregate memory or CPU utilization statistics.

I strongly suggest using WMI as the new windows ZP gets you FAR more than perf data. While there is some setup, one account with correct privileges in AD should do the job for everything you want to monitor

Hello,
I am agree with Trelane use WMI.

Hi All,
If you wan to get the most sophisticated monitoring, than the new Microsoft Windows ZenPack will do the job for you. However, be careful with it! If your Windows is not a "standard" U.S. English one than you may run into trouble as I did. My Windows server is a Hungarian SBS 2011 Essentials. The mentioned ZenPack was able to model my device completely, but wasn't able to gather even a single piece of performance data. So all my graphs remained empty. Also, WinRM requests failed on my server causing some loops in processes started by them. As a result, I got 50-100% processor load. At the end I removed the ZenPack, enabled the SNMP service on my Win box and readded the server to Zenoss as a Windows device. To my best knowledge, that device class uses SNMP queries for windows monitoring. It has a WMI subclass divided further for AD, 2008 and 2008R2. (My device was moved into the latter)
I don't know what exact plans Microsoft has with SNMP and WMI, but the fact is that on SBS 2011 Essentials SNMP is offered as a standard service. I did not deploy the Informant SNMP agent. WMI and/or SNMP provides less detailed monitoring but without any errors and with no load on CPUs.
I tested both methods and both of them are working. In my case the WMI method gave more detailed monitoring (better templates for Windows)
