Affects both templates:
Orion Server 2020.2 - Additional Polling Engine
Orion Server 2020.2 - Main Polling Engine
These templates contain a component, TCP Port Usage Count, a PowerShell Script component with the default Execution Mode set to Local Host. When the targeted Polling Engine (APE A) is monitored by a different Polling Engine (APE B), the component assigned to APE A will by default actually show you TCP Port Usage Counts from APE B. So later when you receive an alert related to TCP Port Usage Count being high on APE A, it will actually be a problem on APE B.
Solution: Change the template's Execution Mode to Remote Host so it runs on the assigned server.
