Stub Analytics Plugin builds successfully but is not detected by Nx Witness

shivi

Hello Nx Team,

I am developing an analytics plugin using the Nx Witness SDK.

Environment:
- Nx Witness Version: 6.0.6.41837
- SDK Version: 6.0.6.41837
- OS: Ubuntu Linux

Problem:
The stub analytics plugin builds successfully and generates:
libstub_analytics_plugin.so

However, Nx Witness does not detect or show the plugin in the Desktop Client.

What I have done:
1. Built the plugin using CMake successfully.
2. Copied the generated .so file into the Nx Witness plugins directory.
3. Restarted the mediaserver service.
4. Checked mediaserver logs.

Expected:
The analytics plugin should appear in Nx Witness.

Actual:
The plugin is not visible.

Logs:
sudo journalctl -u networkoptix-mediaserver.service -f

I would like to know if any additional files are required, such as:
- manifest.json
- specific folder structure
- plugin registration steps

Thank you.

    Hi 

    Thanks for your question, but it seems the procedure is not the recommended one.Can you please provide how you build the plugin and the screen recording if any (also your OS configuration and the build environment)?

     

    I would like to know if any additional files are required, such as:
    - manifest.json

    No, not necessary, it is in STUB plug already.

    - specific folder structure

    No, it is a ready-to-run and one-click build via the build script.


    - plugin registration steps

    No, just the copy then paste the *.so is OK.

     

    And the version you used are kind of out-dated, please use the latest version of Nx Witness and the SDK , thanks for your understanding.
