APM for third party Apps

Hello Everyone,

I would like to ask that APM is feasible for COTS(Commercial Off-The-Shelf)applications like Microsoft Office, customer relationship management (CRM) platforms such as Salesforce, design software like AutoCAD and the Adobe Creative Suite, operating systems like Windows, web browsers such as Chrome and Firefox, and communication tools like Zoom and Slack . We don’t have the code access can we instrument the application performance.

Yes, APM (Application Performance Monitoring) is possible for third-party or COTS applications even if you don't have access to the source code. Most modern APM tools provide agent-based or agentless monitoring, which can track performance metrics such as response time, resource usage, crashes, and errors at the system, network, or API level. For applications like Microsoft Office, Salesforce, AutoCAD, or Zoom, you can monitor user experience, system calls, and external integrations without making any changes to the application code.

Thanks @williamchan

But is there any documentation we can follow.
