This counter tracks how many prefix consistency queries this specific checker has sent to the CEF forwarding databases. This is essentially the checker's own workload counter, and comparing it against cefCCQueriesChecked and cefCCQueriesIgnored tells an admin whether the checker is actually completing its queries or dropping a significant fraction due to internal errors. If this counter is climbing steadily but cefCCQueriesChecked lags far behind, an admin would suspect the checker itself is resource-starved or hitting internal failures rather than the FIB being unusually inconsistent.
