Please note that this article is superseded by the following documentation:
Update the SolarWinds MIB Database for the SolarWinds Platform

SolarWinds maintains a MIB database that serves as a repository for the OIDs used to monitor a wide variety of network devices. The MIB database is updated regularly.
When you are creating a UnDP poller and cannot find an OID in the MIB tree, update the MIB database.

NPM 2020.2 and later

Starting with SolarWinds Platform 2020.2, you can download the MIBs database directly from the SolarWinds Platform Web Console.

Log in to your SolarWinds Platform Web Console.
Click All Settings > MIBs Management.
The page informs you about your installed MIBs database and about the latest available version.
If an updated version of the MIBs database is available, click Download.
This downloads the latest version of the MIBs database as a MIBs.msi file. Beginning in 2025.2, this will be a MIBsv2.msi file.
After the download completes, run MIBs.msi installer and complete the installation wizard.
The Installer informs you when SolarWinds Platform services need to be restarted and restarts them if necessary.
Run the .msi file on all deployed polling engines - on the main polling server, HA backup server, and any additional polling engines.

NPM 2019.4 and earlier

The following process is the only option for updating the MIBs database for SolarWinds Platform 2019.4 and earlier. The process also works for later versions.

Log in to the Customer Portal (http://www.solarwinds.com/customerportal/) using your SolarWinds Customer ID and Password.
Click Downloads > Orion MIB Database > Download Orion MIB Database.
If you are using Internet Explorer and it prompts you to add the SolarWinds downloads site http://solarwinds.s3.amazonaws.com, add the site to your trusted sites.
Specify a location where the file will download.
After the download completes, extract MIBs.zip to a temporary location.
Open the folder with the extracted MIBs.zip, and copy MIBs.cfg to the SolarWinds folder on your default install volume.
- The default location depends on the operating system. For example, on Windows Server 2012, MIBs.cfg is located in C:\ProgramData\Solarwinds.
- If you have High Availability (HA) deployed, copy MIBs.cfg to both HA servers.
- If you cannot overwrite MIBs.cfg because it is being used by a service, Shutdown and restart Orion services, overwrite MIBs.cfg, and restart the service again.
- You may need to restart the Universal Device Poller after installing the MIB database.

Note: The updated MIBs.cfg is immediately used.

If the installer fails to complete, see MIBs database installer fails to complete successfully in SolarWinds Platform 2025.2, 2025.4 and 2026.1 for troubleshooting information.
