This read-only Gauge32 counts the number of packets dropped that matched this rule, measured over the past active minute. An admin uses this to pinpoint which application-level rule is currently losing packets, narrowing the search from an appliance-wide drop symptom down to a specific traffic class. For example, isolating packet drops to the rule matching a specific SaaS application over the last minute tells the admin to focus remediation on that application's path rather than the whole WAN link.
