Diameter Server Accounting Measurements

The values on the Diameter Server Acct tab report the processing measurements for accounting transactions when the Diameter protocol is used in a AAA Server Node test case.

The values on the CDF Session tab report the processing measurements for (Diameter protocol) offline accounting transactions in OFCS Node testing.

The values on the CTF Session tab report the processing measurements for (Diameter protocol) offline accounting transactions in OFCS Nodal testing.

NOTE: When Multiple Node Functionalities is selected on the OFCS Node Emulator Configuration or OFCS Nodal Test Configuration tabs, processing measurements for (Diameter protocol) offline accounting transactions are displayed on CDF Session PGW and CDF Session SGW tabs (OFCS Node) or CTF Session PGW and CTF Session SGW tabs (OFCS Nodal).

Measurement Values

In the default view, the Reports tab displays the Summary view, which summarizes the measurements for the test session. If your test includes multiple test cases, you can view the report for a single test case by changing the report view...

Unless otherwise noted, cumulative values report the number of occurrences or rates calculated since the start of the test, and per-interval values report the number of occurrences or rates calculated during the interval. You can view either by changing the measurement values...

Elapsed Time is the first measurement on every tab. It reports the amount of time between the start of the test and the end of the report interval.

Test Iteration reports the current iteration in a repeating test session. It is only displayed when a Number of Iterations is defined for the test session.

Message Counters

The following measurements record the number and types of accounting messages sent by the AAA node and received from all NAS SUTs.

Accounting Starts Received
Accounting Stop Received
Accounting Interim Update Received
Accounting Responses Sent

Condition Change

Condition Change indicates the change in charging condition: Qos change, tariff time change, etc, which causes:

sending of Accounting-request
- volume counts container closing for an IP-CAN bearer.

- Condition Changes: QoS Change Received — 2
- Condition Changes: Volume Limit Received — 3
- Condition Changes: Time Limit Received — 4

Accounting Output Octets Received — Indicates the total number of Output Octets received.
Accounting Output Packets Received — Indicates the total number of Output Packets received.
Time Usage Received — Indicates the total Account Duration Received.

Error Counters

The following measurements report the number of transaction failures by cause.

Poorly Formed Accounting Requests — The number of accounting requests received from a NAS that were incorrectly formatted.
TS Session Timeouts — The number of times an accounting session's timer expired when the AAA node is operating in Stateful mode. Any subsequent requests related to the session are rejected with an Unknown Session ID error. It will be pegged when OFCS doesn't get interim report within the interval value AII (Actt-Interim-Interval) configured on Rf -> CDF App Tap, OFCS waits till the exact value set for the interim report interval, and it will lose the session when it gets time-out event.
No Free Accounting Session Errors — The number of times a NAS attempted to start an accounting session after the maximum Accounting Sessions was reached. An Out of Space error is returned to the NAS.
Send Error — The number of times TCP was temporarily unable to transport a message.
