Category: System Diagnostics Namespace: CMS.Plugin.FlowManagement.Domain.FlowBusiness.Activitys Base Class: ActionActivity Module: FlowManagement.Domain

Overview

DotNetStackActivity (Stack Trace) is a node used to obtain thread stack traces in the process. It inherits from ActionActivity and uses the dotnet-stack tool to print the stack trace of each thread in the target process, used for diagnosing performance issues.

Configuration Description

Property Name	Type	Required	Default	Description
OutputPath	string	No	logs/diagnosis_logs	Diagnosis Output Path
PendingWorkItemThresholdCount	int?	No	-	Thread pool queue threshold, stack trace executes only when exceeded

Usage Examples

{
  "Type": "DotNetStackActivity",
  "Name": "Stack Diagnosis",
  "Alias": "StackDiagnosis",
  "OutputPath": "C:\\Logs\\Diagnosis",
  "PendingWorkItemThresholdCount": 200
}

Notes

• 💡 Executes asynchronously, does not block the process.
• 💡 Setting a threshold can avoid frequent stack trace execution.
• ⚠️ Requires dotnet-stack tool to be installed.
• ⚠️ Stack tracing incurs some performance overhead.
