Monitor instances for nodes and pool members are not re-enabled by an incremental sync. If you set a monitor to be disabled and then perform a sync, when you later set the monitor to enabled, a subsequent incremental sync does not update the monitor status to enabled.
The effect is that the monitor status does not update.
This occurs after disabling a monitor, syncing a configuration, enabling the monitor, and incrementally syncing the configuration.
You can work around this by forcing a full load sync from the active device. Either use 'Overwrite Configuration' on the Device Management Overview page, or the tmsh command 'modify cm device-group device_group_name> devices modify { current_device_name { set-sync-leader } }'.
Monitor instance is now correctly enabled or disabled after an incremental sync.
