But sometimes you’ll want to look up a custom OID so you can add it to your monitoring by hand. Some network systems, like Auvik, already contain the OIDs for a huge variety of devices. Once you know the manufacture, you can look up documentation if needed. Manufacturer information can often be difficult to find in any other way so the OID comes in quite handy in that regard. OID data can also be used to determine the vendor that manufactured the device, just as MAC addresses on networking hardware can usually be traced to specific vendors.

Another OID might tell you about uptime, while a third OID reveals details about fan speed. For example, you can grab an OID that tells you about the temperature of a device. The OID is based in part on the Management Information Base, or MIB, to which the device belongs.Įach OID contains information about a particular aspect of a device, which can be helpful when troubleshooting a network or studying the network topography. What’s an OID?Īn OID is a unique identifier assigned by the SNMP protocol to the various components of individual devices. Is there a device on your network that you want to learn more about or monitor? Being able to look up the device’s Object Identifiers, or OIDs, is the key to gleaning the information you’re after.
