The DA shows degraded due to Threshold State.
DX NetOps CAPM 20.2 or later
The threshold state is degraded when the threshold of 80% poll time is being approached. It recovers and becomes green when that value drops.
There is a threshold monitoring dashboard you can use to monitor the condition of the engine as per:
TechDocs : DX NetOps 23.3 CAPM : Threshold Monitoring and Threshold Limiter Behavior
And there are also administrative events you can look for in your events dashboard.
