Digi AnywhereUSB/14 monitoring through SSH CLI
Monitoring of Digi AnywhereUSB devices via SNMP is very poorly implemented by DIGI. Therefore, I ask you to implement monitoring through SSH
I will give a number of commands that may be useful to us
As I understand it, the last column is the percentage of flash usage:

It is very important to check the group number here. There are 14 groups in total (1 ... 14). Group numbers must be allowed to be described as a plugin option. For example, by default, all groups from 1 to 14 are checked. If there is no group in the connection list, then this is a problem. We also need to be allowed to select group numbers from the list. For example, if we need to check only some groups of 1,3,5-8 (like --check-usb-groups = '1,3,5-8')

Here, I do not understand why the SSH Server service is displayed in the off status Perhaps it makes sense to add an option that allows us to customize the list of services whose status should be "on" Important services for USB ports:
- RealPort Service
- Encrypted RealPort Service
- Anywhere/USB Service
Additionally, you can implement a check for service TCP-listeners (and UDP-listeners)

Do you know if there is an option or a command to display output in xml, csv or xml ? The df command result is in bytes ?
to display output in xml, csv or xml
I did not find such an option.
The df command result is in bytes
I do not know. The problem is that on the DIGI website I did not find information about the commands. I tried, but the df command does not accept any options.

I think the last column shows the percentage of used space. WEB = 2% CFGDATA = 18%
