If you have a node name map file typically used with Subnet Managers, you can provide that file to the `--ibnetdiscover.node-name-map` flag. This will use friendly names for switches.
Even without this flag, exporter still adds the `switch` label populated with whatever hostname (or GUID-style placeholder) ibnetdiscover returns.


If you wish to run the exporter as a user other than root and do not want to use sudo, you must make the UMAD device read/write to all users with something like the following:

```
$ cat /etc/udev/rules.d/99-ib.rules
$ cat /etc/udev/rules.d/99-ib.rules
KERNEL=="umad*", NAME="infiniband/%k" MODE="0666"
```
