 The capability to monitor networks using Linux-based nodes is currently in preview. Reach out to your Account Manager to know more. Linux agents provide monitoring capability only for NPM's Performance Monitor capability, and are not available for the Service Connectivity Monitor and ExpressRoute Monitor capabilities
 
 ### What are the size requirements of the nodes to be used for monitoring by NPM?
-For running the NPM solution on node VMs to monitor networks, the nodes should have at least 500-MB memory and one core. You do'nt need to use separate nodes for running NPM. The solution can run on nodes that have other workloads running on it. The solution has the capability to stop the monitoring process if it uses more than 5% CPU.

 ### To use NPM, should I connect my nodes as Direct agent or through System Center Operations Manager?
 Both the Performance Monitor and the Service Connectivity Monitor capabilities support nodes [connected as Direct Agents](../../azure-monitor/platform/agent-windows.md) and [connected through Operations Manager](../../azure-monitor/platform/om-agents.md).

 ### Which protocol among TCP and ICMP should be chosen for monitoring?
 If you're monitoring your network using Windows server-based nodes, we recommend you use TCP as the monitoring protocol since it provides better accuracy. 
 
-ICMP is recommended for Windows desktops/client operating system-based nodes. This platform does'nt allow TCP data to be sent over raw sockets, which NPM uses to discover network topology.
