Term Definition
Round Trip Time- The time interval between the most recent Accounting-Response and the Accounting-
Request that matched it from this RADIUS accounting server.
PendingRequests- The number of RADIUS Accounting-Request packets sent to this server that have not yet
timed out or received a response. This variable is incremented when an accounting-Request
is sent and decremented due to receipt of an Accounting-Response, a timeout or a
retransmission.
Retransmissions- The number of RADIUS Accounting-Request packets retransmitted to this RADIUS
accounting server. Retransmissions include retries where the Identifier and Acct-Delay have
been updated, as well as those in which they remain the same.
Timeouts- The number of accounting timeouts to this server. After a timeout the client may retry to the
same server, send to a different server, or give up. A retry to the same server is counted as
a retransmit as well as a timeout. A send to a different server is counted as an Accounting-
Request as well as a timeout.

Malformed packets include packets with an invalid length. Bad authenticators and unknown
types are not included as malformed accounting responses.

authenticators received from this server.

the accounting port.

and dropped for some other reason.

retransmissions.
