Cell	Detail
28: Agent	Requires SNMP to be installed on agent server and listening on localhost only. The SNMP information needs to then be added in the SolarWinds Web Console while editing that node. Inside of the Polling Method section for Agent, you’ll check the box ‘Include SNMP Credentials’ and update it with the respective SNMP information.
31: Agent	"Partial" assumes the Orion Server or Additional Polling Engine the node is associated with has routable connectivity to the agent-managed node. The Web Based SSH Client communicates over TCP Port 22 from the Orion Server or APE to the selected node, and does not utilize the agent communications channel.
105: Agent	Linux agent supports ADM functionality for Intel based servers only. ADM is not supported by the Linux agent for ARM processors (Raspberry Pi).
