Not sure if this is already possible through some workaround or not. If it is, I can't figure out how

All my servers have some form of out-of-band management card or connection (Dell BMC, Dell DRAC, HP ILO, Generic IPMI, etc). This connection has a separate IP address that doesn't show up anywhere. I'd like to monitor some things from that connection and propagate it as part of the device status.
Optimally, I'd like to just add DCIs and select the IP address of the management card. Come to think of it, you'd need more than just the IP address: you'd need almost all the communication settings. Perhaps this is actually a device as a child of another device?
