Measures reported by IasAccClientTest

Besides providing remote authentication services to RADIUS clients, the IAS server also provides a central accounting recording service for all accounting requests that are sent by the RADIUS clients. Once the IAS server completes the connection process initiated by a RADIUS client, the access server which processed the connection request sends an Accounting-Request message to the IAS server, where the message is logged. The IAS server then sends an Accounting-Response to the access server. In addition, the access server also sends Accounting-Request messages for the following:

  • During the time in which the connection is established
  • When the access client connection is closed
  • When the access server is started and stopped

The IasAccClientTest monitors the accounting-requests sent and accounting-responses received by the RADIUS clients from the IAS servers.

Measurement Description Measurement Unit Interpretation
Packets_sent The rate at which packets were sent by this client Packets/Sec  
Packets_received The rate at which this RADIUS client received packets Packets/Sec When viewed along with the Packets_sent measure, this measure serves as a good indicator of the traffic that originated from a 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_types The rate at which packets of an unknown type were received Packets/Sec  
No_records The rate at which RADIUS Accouting-Request packets were received and responded to but not recorded Records/Sec  
Accounting_requests The rate at which RADIUS Accouting-Requests were sent by this client on the accounting port Reqs/Sec  
Accounting_responses The rate at which RADIUS Accouting-Response packets were sent to this client on the accounting port Reqs/Sec The Accounting_requests and Accounting_responses measures serve as effective indicators of the workload on the client.
Duplicate_acc_requests The rate at which duplicate RADIUS Accouting-Request packets were received from this client Reqs/Sec  
Bad_authenticators The rate at which Accounting-Requests containing invalid signature attributes were received Reqs/Sec
