Note: Before you spend your time searching for MIBs and custom OIDs, check PRTG's built-in SNMP libraries first and start an auto-discovery! PRTG will create sensors and channels for all available monitoring objects automatically.

If your device is not covered, you can start searching for custom MIBs/OIDs.

Where to Find MIB Files

1. Often, device specific MIBs are available on the manufacturer's website. If you do not get MIBs there, contact the manufacturer's customer support.

2. You can also search in general databases on the web. The following websites offers an extensive selection of MIB (Management Information Base) files:

• mibdepot.com
• circitor.fr

More links and resources can be found at SNMPLink.org.

Once you've found the MIB files you need, please see How can I import my MIB files into PRTG? for instructions on how to use them.
