  4. Query results appear in a new tab. If query results do not appear, see Debug Flux queries.

Explore your schema

After you’ve configured an InfluxDB connection, VS Code provides an overview of buckets, measurements, and tags in your InfluxDB organization. Use the InfluxDB pane in VS code to explore your schema.

Upgrade the Flux extension

VS Code auto-updates extensions by default, but you are able to disable auto-update. If you disable auto-update, manually update your VS Code Flux extension. After updating the extension, reload your VS Code window (Ctrl+Shift+P, and then Reload Window) to initialize the updated extensions.
