Despite the description's wording being inherited from the authentication table, in this accounting-specific table this counter tracks session-accounting request packets sent to the server, so the admin should read it as a volume of accounting records transmitted, such as session start, stop, or interim updates, not as login authentication attempts. For example, this counter roughly tracking twice the number of actual login sessions, one record for session start and one for stop, would confirm the accounting client is generating both start and stop records as expected.
