• I had searched in the issues and found no similar feature requirement.

Description

1. Entry Point: - Add a "View Logs" option within the Action Button menu (or Action group) of each RayCluster in the cluster list/detail view.

2. Interaction: - Clicking "View Logs" will open a Modal or a Side Drawer containing the Log Viewer.

3. Log Viewer Component:

   • A dedicated terminal-like interface built with @mui/joy.
   • Support for auto-scrolling and basic keyword highlighting (ERROR/WARN).

4. Add Download button in the log view to download the logs file

Technical Details

• API Endpoint: /api/v0/logs/file
• Data Format: Plain text (verified here)
• Component Stack: @mui/joy (Sheet, Typography, Stack, etc)

Proposed Implementation Path

1. New Component: Create dashboard/src/components/LogViewer.tsx using Joy UI Sheet and Typography to render plain-text logs with auto scroll support.
2. API Integration: Implement a new data-fetching hook in dashboard/src/hooks/api/useGetLogs.ts to interface with the /api/v0/logs/file endpoint.
3. UI Entry Point: Add a "View Logs" button to the Actions column in dashboard/src/app/history/raycluster/page.tsx .
4. User Experience: Clicking the button will trigger a Modal to display the log stream for the specific node.

View Logs button can be an Icon
