Hi RAQS,
If there is a monitor assigned to a pool or pool member, monitor requests are sent to the server, regardless of enable or disable. You can see this with tcpdump.
tcpdump -ni any host <non-floating-ip> and host <pool-member-ip> and port <pool-member-port>
When the member is disabled or force-offline, the active connections continue.
Status Indicator
● Black Circle: member disable and available
⯁ Black Diamond: member disable and unavailable
◼ Black Square: member disable and availability is unknown(no monitor)
