    Zabbix Queue: Passive vs Active

    Hi guys, just wanted to confirm some things I am noticing about the Zabbix Queue.

    Previously I had all my Windows Agents using the passive agent checks (Zabbix 5). The queue length was always zero (or pretty close to it).
    I now have them set to Active (because I like receiving data instead of requesting it) and I notice the queue length has grown.

    Is this expected? Am I right in assuming the queue length is now non-zero because Zabbix is "waiting" for these item values to be sent by the agents?

    How can I diagnose a high queue length (or how can I tell what items a Zabbix Agent has NOT yet sent, from the agent's perspective). I often see in some environments that an Agent will often not send data until it's restarted with no real reason as to why.

    Cheers
