Executing `meteor node -e "console.log(process.versions)"` would
run `console.log(process.versions)` in the version of `node` bundled with Meteor.
## meteor profile {meteorprofile}
The `meteor profile` command runs a performance profile for the Meteor application,
monitoring the bundler process and tracking key performance metrics to help analyze
the build and bundling performance.
The options for this command are the same as those for the `meteor run` command.
You can pass typical runtime options (such as --settings, --exclude-archs, etc.)
to customize the profiling process.
You can use `--size` to monitor both the bundle runtime and `--only-size` to monitor
only the bundle size, allowing you to assess the impact of changes on the overall build
size.
Use `METEOR_IDLE_TIMEOUT=<seconds>` to set a timeout for profiling. The default time (90s)
is usually enough for each build step to complete. If you encounter errors due to
early exits, adjust the environment variable accordingly.
Use `METEOR_CLIENT_ENTRYPOINT=<path-to-file>` to set a custom client entrypoint, and
`METEOR_SERVER_ENTRYPOINT=<path-to-file>` to set a custom server entrypoint. By default,
it uses the server and client entrypoints specified in your package.json.
Use `METEOR_LOG_DIR=<path-to-directory>` to set a custom log directory.
