Target of the test : An NPS server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for every NPS server that is being monitored

Configurable parameters for the test

Test period	This indicates how often should the test be executed.
Host	The host for which the test is to be configured.
Port	The port at which the NPS server listens. The default is NULL.

Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
Packets sent	Indicates the rate at which packets were sent by this client to the NPS server.	Packets/Sec
Packets received	Indicates the rate at which this client received packets from the NPS server.	Packets/Sec	When viewed along with the Packets sent measure, this measure serves as a good indicator of the traffic on the client.
Packets dropped	Indicates the rate at which incoming packets were silently discarded for a reason other than being malformed, bad authenticators, or unknown types.	Packets/Sec	A consistent increase in the value of this measure is a cause for concern, and might warrant further investigation.
Malformed packets	Indicates the rate at which malformed packets were received; bad authenticators or unknown types are not included in this count.	Packets/Sec
Unknown packets	Indicates the rate at which packets of an unknown type were received.	Packets/Sec
Access accepts	Indicates the rate at which RADIUS Access-Accept packets were sent to this client.	Accepts/Sec
Access challenges	Indicates the rate at which Access-Challenge messages are being processed.	Challenges/Sec
Access rejects	Indicates the rate at which Access-Reject messages are being processed.	Rejects/Sec	A very high value of this measure could warrant a review of the remote access policies.
Access requests	Indicates the rate at which packets were received on an authentication port from this client.	Reqs/Sec
Bad authenticators	Indicates the rate at which packets containing invalid signature attributes were received.	Reqs/Sec
Duplicate requests	Indicates the rate at which duplicate RADIUS Access-Request packets were received from this client.	Reqs/Sec
