SAM Process Monitor- Windows shows as down when it is running.
This article discusses an issue when an Application Performance Monitor (SAM) process component Monitor may intermittently report a status of Down even though the monitored executable is confirmed to be running on the target server.

Overview
SolarWinds SAM process monitors- Windows rely on Windows management interfaces (WinRM, WMI/RPC, or Agent-based polling) to collect performance data such as CPU, memory usage.
When WinRM is configured as the preferred polling method, the platform will attempt to collect process metrics using WinRM first. If WinRM is unavailable or not properly configured, SolarWinds will fall back to an alternative method (such as WMI/RPC).
For process monitors, SolarWinds requires two successful measurements of the same process instance (PID) within a single polling cycle to calculate delta-based metrics. If either measurement fails or is delayed, the process status may be reported as Down or NotAvailable.

Cause
This issue is caused by WinRM timeouts delaying the polling cycle, which prevents SolarWinds from completing the required two-sample process measuremen
Resolution
Option 1: Change Fetching Method to RPC
1.1. Configure the application or node to use RPC (WMI) instead of WinRM for application polling.
1.2 Hit Save and Submit.
Option 2: Use Agent for Application Polling
Deploy the SolarWinds Agent on the target node and configure the application to use Agent-based polling.
