Using GetIf to discern OIDs

GetIf is a handy little tool that can be used to ascertain and discern OIDs which, in turn, can be used to access custom sensor information under PRTG Traffic Grapher. Setting up GetIf is quick and simple. Simply download the data files from http://www.wtcs.org/snmp4tpc/getif.htm, execute the Setup routine and GetIf will automatically install itself on your machine.
Then, start the program from the GetIf program group (Start | Programs | GetIf). You will need to enter the IP address for the server upon which you would like to look up the OIDs. You will also need to define various SNMP parameters (such as the Read / Write community strings).
In order to then access the OIDs, click on the “MBrowser” tab. If all was set up properly, you will notice boxes which, upon clicking on them, will open into a tree structure. At the bottom left, you will notice a number – this number is the OID. The further you go in the tree structure, the longer the number should get, as the individual nodes are being added to the OID value.
Find the device you are wanting to use in PRTG Traffic Grapher and use the OID value presented by GetIf in order to set up a custom sensor – in this manner you can configure your own devices which might not be accessible directly from the provided libraries.
