Here is my quick guide for monitoring a Darktrace Artificial Intelligent Master or Probe appliance with SNMPV3.
This is a Darktrace Probe appliance... rack it up, plug it in and patch it in as per Darktrace's instructions.

Putty onto the appliance.


Click yes to trust the host.
Login as console :

Enter your SSH password
Select Darktrace Appliance from the Menu Items. Select enable SNMP.
Select Security name and enter name.
Select Authentication Type and Passphrase.
Select Privacy Protocol and Passphrase.

Click Yes and save the configuration. Close SSH connection.
Add the node into Solarwinds as SNMPV3 node.

Remember to enter in the username which in this case is monitor and the authentication and encryption method.
Submit.
Darktrace is now monitored.
