Where is the log file located in for NPM and other modules

C:\ProgramData\SolarWinds

programdata is a hidden folder. you may need to enable that from windows explorer's folder options.  you can also simply type c:\programdata in the file path and it will take you there

Thanks a lot HolyGuacamole‌.. Just one more query related to this. Since the logs are stored in C drive and not the installation drive, then approx how much space does it take on C drive? The reason for asking is we are having less space left currently on C drive.

Hard to tell. On my server, it is using less than 5 GB

Ok...No issues...:-)

**Just for others if need to Examine what is going inside the logs **

We have tool called  "Orion Diagnostics" Tool where you can select the Logs to fetch from the system according to your requirements and save in a folder for examine .

You can further go to each module and select what exactly you need to see.

Hey Thanks for this info.
