Measures reported by IasAuthClientTest
Internet Authentication Service (IAS) can be used as a RADIUS server to perform authentication, authorization, and accounting for RADIUS clients. When Internet Authentication Service (IAS) 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. IAS 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. IAS uses the dial-in properties of the user account and remote access policies to authorize a connection.
The IasAuthClientTest monitors the access-requests sent by access-clients to the IAS server, and indicates how many requests were accepted/rejected by the IAS server.
| Measurement |
Description |
Measurement
Unit |
Interpretation |
| Packets_sent |
The rate at which packets were sent by this client to the IAS server |
Packets/Sec
|
|
| Packets_received |
The rate at which this client received packets from the IAS 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 |
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 |
The rate at which malformed packets were received; bad authenticators or unknown types are not included in this count |
Packets/Sec
|
|
| Unknown_type |
The rate at which packets of an unknown type were received |
Packets/Sec
|
|
| Access_accepts |
The rate at which RADIUS Access-Accept packets were sent to this client |
Accepts/Sec
|
|
| Access_challenges |
The rate at which Access-Challenge messages are being processed |
Challenges/Sec
|
|
| Access_rejects |
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 |
The rate at which packets were received on an authentication port from this client |
Reqs/Sec
|
|
| Bad_authenticators |
The rate at which packets containing invalid signature attributes were received |
Reqs/Sec
|
|
| Duplicate_acc_requests |
The rate at which duplicate RADIUS Access-Request packets were received from this client |
Reqs/Sec
|
