If you are able to manually add the OID when configuring the SNMP monitor but unable to browse the MIB after attempting to load it, the most likely cause is that the MIB has a dependency that cannot load.

There are a few ways to verify this cause:

• In your browser's Java Console, you will see an error similar to the following:
  java.io.FileNotFoundException: http://<uptime_host>:9999/MIB/<DEPENDENT_MIB>
• In the MIB file itself, there will be an IMPORTS section that has other optional or required MIBs that try to load.

To resolve this issue, ensure that any dependent MIBs are placed in the /<uptime dir>/GUI/MIB directory of the monitoring station server.
