Installing additional MIB files

Before you install custom or additional MIB files,

Create an uploadedMIBs directory as described in Importing pre-loaded MIB organizers and files.
If you want to load MIBs into a MIBs organizer that does not exist, create the organizer as described in Creating a MIBs organizer.

Perform these steps:

Log in to the Control Center master host as root or as a user with superuser privileges.
Copy any MIBs and their dependencies that you want to install into the /opt/serviced/var/volumes/<instance_id>/zenoss-var-ext/uploadedMIBs directory on the Control Center master host. Replace <instance_id> with the appropriate ID for your instance. After those files are copied to that directory, they are immediately available inside containers at /opt/zenoss/var/ext/uploadedMIBs with no restart needed.
Execute the following command to install the MIB. Include --removemiddlezeros if MIBs use notification OIDs with embedded zeros. Include --path to specify an existing MIBs organizer in which to load the MIBs.
```
serviced service run zope zenmib run -v10 /opt/zenoss/var/ext/uploadedMIBs/<mib_filename> \
  --path=/zport/dmd/Mibs/<mibs_organizer> --removemiddlezeros --mibdepsdir=/opt/zenoss/var/ext/uploadedMIBs
```
Restart the zope service and any instances of the zentrap service.
