Couldn't get correct value of the SNMP OID "memTotalFree"

[Bing Wen]

Hi All,

I am a new guy using NetXMS and I met a issue as below. Would you please help to have a look? Thanks in advance.
I want to monitor the Memory usage of a server which runing Windows OS. I have enabled the SNMP server on the server and I could get the correct value of OID "hrMemorySize"(.1.3.6.1.2.1.25.2.2.0) by "Node" -> MIB explorer -> Walk -> Create data collection item.
But I couldn't get the correct value of the SNMP OID "memTotalFree"(.1.3.6.1.4.1.2021.4.11.0). Firstly I tried to Wlak it on "MIB explorer" but get nothing. Then I tried to create a "new parameter" on "Data Collection Configuration", I set the parameter as  "Internal" and "Dummy" , and set "transformation script" as "transport = CreateSNMPTransport($node); memTotalFree = SNMPGetValue(transport, ".1.3.6.1.4.1.2021.4.11.0"); ", and set all the other parameter as default value, and I get the latest value is just 0.
So if I missed something in understanding and configuration? How could I get the value I wanted, such as CPU usage, memory usage, disk usage and so on? Is there any other easier way to get these info by using NetXMS?

At last, The result of "Poll configuration" in my environment as below FYI.

Hi

I just tested on a Win2012R2 node. The same here. I don't think Windows supports .1.3.6.1.4.1.2021 (UCD-SNMP-MIB). Maybe installing the NetXMS agent on the Windows nodes would be the better solution for you.

Hi Dani@M3T,

 :)Thank you for your kindly reply. But the target server with Windows server 2008 don't allow to be installed with any other agent, it only allow to install the SNMP feature and  enable SNMP service. So is there any other way to monitor the server for Memory/CPU/Disk usage based on SNMP? Like script? Like template?

hostmib is supported by Windows SNMP server (OID: .1.3.6.1.2.1.25). You can have a look there,maybe you found something usefull.
Try also .1.3.6.1.4.1.77 (but I don't have installed the mib)
In .1.3.6.1.2.1.2 you find network related things.

Try also DCI with Origin 'Windows Performance Counters', but no, this needs the agent

Thank you very much. I will learn these OIDs.
