Metadata introspection for the NVIDIA monitor plugin used by cjm-ctl to generate the registration manifest

get_plugin_metadata

Returns metadata required to register this plugin with the PluginManager. This function is called by cjm-ctl during the manifest generation phase.

The returned dictionary includes:

• python_path: Absolute path to the environment’s Python interpreter
• module/class: Import path for dynamic loading by the Universal Worker
• resources: Hardware requirements (this plugin doesn’t require GPU itself)

CLI Introspection

The cjm-ctl install-all command runs this function inside the plugin’s conda environment:

conda run -n cjm-sys-mon-nvidia python -c \
  'from cjm_system_monitor_nvidia.meta import get_plugin_metadata; \
   import json; print(json.dumps(get_plugin_metadata(), indent=2))'

The output is written to ~/.cjm/plugins/cjm-system-monitor-nvidia.json.
