A pool-member can have three different states:
– enable (all connections are allowed)
– disabled (only active and persistened connections are allowed)
– force offline (only active connections are allowed)
All these three states will keep the overall pool status as green, because at least active connections (e.g. long term session as FTP or SSH) are allowed.
The status of a pool will only turn into red, if all pool-members are marked as down by its monitor.
