ProcInsp is windows process and stack explorer with web UI. ProcInsp shows list of running processes on multiple (remote) servers. You can drill down into the CLR-process and watch running threads with their stacktraces. ProcInsp also allows to watch current executing requests on IIS AppPools (w3wp workers).

Servers and procs

Features

• Displays RAM and CPU usage of connected servers
• Displays info about running processes on all connected servers (RAM, CPU, start time etc)
• For IIS processes - the name of apppool is displayed
• Kibana integration - user can view logs of desired process (logs are filtered by host name and process id; Kibana url in configurable)

Threads and requests

Features

• Displays currently running requests (only for IIS processes)
• Displays all running threads of process
• App's entry point in stacktrace is shown as thread's name (which frame should be considered as entry point is configurable)
• If exception in thread occured, exception info is displayed (exception type, message and stacktrace)
• Kibana integration - user can view logs of desired thread (logs are filtered by host name, process and thread ids; Kibana url in configurable)

Stacktrace

Features

• Highlight app's entry point in stacktrace (which frame should be considered as entry point is configurable)

API

ProcInsp has public API, which returns results in JSON.

Verb	URL	Description
GET	/Process	Get the list of running processes
GET	/Process/{pid}	Get information about specific process
GET	/Process/usage	Get resource usages (CPU/RAM) by processes
GET	/Process/machine	Get total resource usage (CPU/RAM) on machine
GET	/Process/{pid}/threads	Get threads of CLR process
GET	/Process/{pid}/threadSizes	Calculate threads' sizes of CLR process (WARNING: doesn't work correct)
GET	/Process/{pid}/requests	Get web-requests serving by specific process. Works only if process is w3wp worker (IIS AppPool)

Full documentation is available at /swagger/index.html (after app is started).

Known limitations

• Shows threads and stacktraces only for CLR processes with the same bitness as running web api server
• Shows only thread IDs and some other basic info for non CLR processes
• Web-requests are shown only for IIS web server

Repository structure

• ProcInsp - web application and api's
• ProcInsp.Tests - tests
• Other projects are just for testing purposes

Run

• You can run application from VS Code (F5)
• Or dotnet run .ProcInsp/ProcInsp.csporj

Publish

• Change version in globalConfig.js
• Run from git root directory:
  • dotnet publish ProcInsp\ProcInsp.csproj
  • npm i
  • npm run zip
• Create new release at GitHub

Deploy

• Prerequsites
  • IIS
  • dotnet core 3.1
• Download latest release from https://github.com/CUSTIS-public/ProcInsp/releases
• Unzip
• Change config in \ClientApp\build\config.js (all available settings are described in https://github.com/CUSTIS-public/ProcInsp/blob/main/ProcInsp/ClientApp/src/globals.d.ts)
• Deploy to IIS (apppool should be managed by admin user)
