Dagu Web UI
Use this skill when working with Dagu's web interface to manage workflows, view execution history, monitor running workflows, or configure the UI.
When to Use This Skill
Activate when:
- Navigating the Dagu web interface
- Starting, stopping, or retrying workflows via UI
- Viewing workflow execution logs and status
- Monitoring running workflows
- Managing workflow history
- Configuring workflow schedules through the UI
- Troubleshooting workflow issues using the UI
Core Capabilities
The Dagu Web UI provides:
- Workflow Management - View, start, stop, and manage workflows
- Execution Monitoring - Real-time status and logs
- History Viewing - Past execution records and results
- DAG Visualization - Visual representation of workflow structure
- Log Access - View detailed execution logs
- Schedule Management - Configure when workflows run
Quick Start
Access Dagu Web UI at http://localhost:8080 (default) after starting Dagu:
dagu serverPrimary Operations
Start a Workflow
To manually execute a workflow:
- Navigate to workflow list
- Click the workflow name
- Click "Start" button
- View real-time execution progress
Monitor Execution
For detailed information on a running workflow, consult references/monitoring.md which covers:
- Reading execution logs
- Understanding status indicators
- Tracking step progress
- Identifying failures
View History
To review past executions, see references/history.md for guidance on:
- Filtering execution history
- Analyzing failed runs
- Comparing execution times
- Exporting execution data
Workflow Visualization
The DAG view shows workflow structure. For detailed visualization features, see references/visualization.md.
When to Consult References
- Detailed UI navigation: Read
references/ui-navigation.md - Advanced monitoring: Read
references/monitoring.md - History analysis: Read
references/history.md - Workflow editing via UI: Read
references/workflow-editor.md - Configuration options: Read

Common Tasks
Restart a Failed Workflow
- Find the failed execution in history
- Click the retry/restart button
- Monitor the new execution
Stop a Running Workflow
- Navigate to the running workflow
- Click "Stop" or "Cancel"
- Confirm the action
- View cleanup handlers execution
View Detailed Logs
When you need to debug a workflow:
- Click on the specific workflow execution
- Select the step with issues
- View stdout/stderr logs
- Check for error messages
For advanced log analysis, consult references/monitoring.md.
Key Principles
- Real-time visibility: Web UI provides live updates of workflow execution
- Click-based operations: No CLI needed for basic workflow management
- History preservation: All executions are logged and accessible
- Visual feedback: Status indicators show current state at a glance
- Log accessibility: Detailed logs available for debugging
Pro Tips
- Use the search feature to quickly find workflows by name
- Filter execution history by date range or status
- Click on step names in DAG view for step-specific details
- Use the refresh button if live updates seem delayed
- Check the scheduler status to verify cron jobs are active
