This object reports the number of Charging Detail Records (CDRs), accounting records for billable connections, currently sitting in the chassis's memory that haven't yet been safely written to permanent storage or sent to a collection device. An admin watching this number grow unusually large would suspect a problem downstream in the accounting pipeline, since CDRs accumulating in memory risk being lost if the chassis resets before they're flushed. If this object climbs into the thousands instead of staying near zero, it signals the configured accounting collection device or disk write path has likely stopped accepting records.
