Re: SNMP vs WMI polling - pros and cons

Another PRO for WMI is that it grabs the "Avg. Disk sec/Transfer", "Disk queue length", "Total Disk IOPS", and "Disk Allocation Failures" for volumes - never seen anything in "Disk Allocation Failures", but that a good thing right?

I am not sure what version added that, but I was messing around with adding the new graphs and saw them and played around till I found that they had data if the server was WMI.

I agree to Leon Adato, You must have both NPM and SAM.

Here's the list resources of NPM only

Here's the list resources after SAM installed (assuming you added application components of this server)

Re: SNMP vs WMI polling - pros and cons

I’d like to see the option to use both SNMP and WMI methods.

I monitor using SNMP across the board, but I want some of the options that WMI monitoring offers such as an account associated with the node (for service control via Solarwinds etc.)  and Disk Performance stats without needing to install “SNMP Informant Standard” on all my servers, or add  additional monitors manually.

I’m not saying that the same info should be gathered by both methods. I’m sure that the bods at Solarwinds know which data is best pulled from SNMP and which from WMI? If not, they could give the admin the choice of setting one as the primary method.

With proper agent configuration, yes. Example (HP server with HP agent).

Re: SNMP vs WMI polling - pros and cons

Hello all,

I'm looking for a definitive answer to just one thing.

Which monitoring protocol, WMI or SNMP, will affect performance of the monitored Windows 2008R2/2012R2 the least? WMI or SNMP? In the context of this question, it is not relevant which reveals any specific metric or health, only which puts more load on the monitored machine(s).

Thank you!!!

Typically SNMP would be considered lighter weight from a host / query / network perspective.
