This flag controls whether SNMP trap notifications related to this specific resource policy get sent at all, and when true, they go out to every remote host already configured to receive SNMP notifications from the device -- there is no per-policy destination override. This means enabling notifications for one resource policy potentially adds trap volume to every existing SNMP trap receiver on the network, not just a dedicated resource-monitoring one, which matters when deciding whether to enable this on a noisy or low-priority policy. Turning this on for a policy monitoring dozens of low-priority per-process memory thresholds would send every one of those threshold-crossing traps to the same trap receiver already getting critical hardware-failure traps, potentially burying the important ones.
