NPS Authentication Server Test
When NPS is used as a RADIUS server, it provides the a central authentication and authorization service for all access requests that are sent by RADIUS clients. NPS uses either a Microsoft Windows NT Server 4.0 domain, an Active Directory domain, or the local Security Accounts Manager (SAM) to authenticate user credentials for a connection attempt. NPS uses the dial-in properties of the user account and remote access policies to authorize a connection.
This test measures how well the NPS server performs remote authentication and authorization.
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
Parameters | Description |
---|---|
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. |
Measurement | Description | Measurement Unit | Interpretation |
---|---|---|---|
Packets sent |
Indicates the rate at which packets were sent by the NPS server. |
Packets/Sec |
|
Packets received |
Indicates the rate at which the NPS server received packets. |
Packets/Sec |
When viewed along with the Packets sent measure, this measure serves as a good indicator of the traffic on the server. |
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. |
Invalid requests |
Indicates the rate at which packets were received from an unknown address. |
Reqs/Sec |
|
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 by the NPS server 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 |
|
Duplicate requests |
Indicates the rate at which duplicate RADIUS Access-Request packets were received from this client. |
Reqs/Sec |
