This read-only Counter64 counts the total number of received IGMP queries this PM instance discarded, for any reason. Admins treat it as a rollup alarm — a nonzero value means one of the specific reason-coded QueryDiscards counters on this same instance is climbing and worth checking individually; because it is drawn from this instance's running statistics bin, it behaves like a long-running total rather than a rotating window, so admins baseline against it instead of expecting it to reset daily. On a subscriber-facing IPTV access port, a count of 2,118 over the current statistics window is the kind of number an admin would trend against the join/leave rate on the same port to judge whether it's normal channel-surfing or an anomaly worth a closer look.
