Why each option
An offline pool status typically indicates that no available pool members are passing their health monitors, making the entire pool unavailable for traffic.
If no monitors are assigned, the BIG-IP by default considers members available unless explicitly disabled or administratively taken offline; it would not automatically show as offline solely due to a lack of monitoring.
If a pool has an assigned monitor and none of its members pass the health check, the BIG-IP marks all members as unavailable, consequently taking the entire pool offline. The red 'offline' status signifies that the pool cannot accept new connections because no healthy members are available.
If some pool members pass the test, the pool would remain online and traffic would be directed to the healthy members, even if others are down.
Monitoring nodes rather than pool members, and all nodes passing, does not directly dictate the pool's status unless those nodes are specifically tied as pool members and their member-level health checks are also passing.
