Collectors and TCP Ephemeral ports exhaustion detection

I have also reduced sample frequency or turned off some of the noisier pieces of WMI... clusters, hyper-v, msmq, and .NET  These all combined made the environments I'd maintained much more reliable.  If you have a 15 minute response time expectation/SLA, you can generally shift to 5 minutes sample time rather than 1 or 3... this will still allow 3 consecutive threshold crossings before producing an alert without impacting your response times.
