#### Permissions
When gathering from the local system, Telegraf will need permission to the
impi device node. When using udev you can create the device node giving
`rw` permissions to the `telegraf` user by adding the following rule to
`/etc/udev/rules.d/52-telegraf-ipmi.rules`:
```
KERNEL=="ipmi*", MODE="660", GROUP="telegraf"
```
### Example Output
When retrieving stats from a remote server:
```
