SM will degrade the node when the FD reaches the limit. Ref SM changes: https://review.opendev.org/c/starlingx/ha/+/819130 TC passed: Alarm is raised when FD limit is reached, or above 95% (approaching). Alarm is cleared when FD usage is below 95% threshold. Upgrade test. New alarm raised on controller-1 (N+1). Alarm is cleared when collectd restarts or node reboot (alarm will be re-raised if alarming situation is dected again) SM detects 161 status code and degraded the node with service degraded alarm. Alarm raised after fm comes back up after being not available. Alarm is cleared after fm comes backup after being not available.
