SGLang CI Monitor

A simple tool to analyze CI failures for the SGLang project. This tool fetches recent CI run data from GitHub Actions and provides detailed analysis of failure patterns.

Features

  • Simple Analysis: Analyze recent CI runs and identify failure patterns
  • Category Classification: Automatically categorize failures by type (unit-test, performance, etc.)
  • Pattern Recognition: Identify common failure patterns (timeouts, build failures, etc.)
  • CI Links: Direct links to recent failed CI runs for detailed investigation
  • Last Success Tracking: Track the last successful run for each failed job with PR information
  • JSON Export: Export detailed analysis data to JSON format
  • Automated Monitoring: GitHub Actions workflow for continuous CI monitoring

Installation

No additional dependencies required beyond Python standard library and requests:

pip install requests

Usage

Basic Usage

# Replace YOUR_GITHUB_TOKEN with your actual token from https://github.com/settings/tokens
python ci_analyzer.py --token YOUR_GITHUB_TOKEN

Advanced Usage

# Analyze last 1000 runs
python ci_analyzer.py --token YOUR_GITHUB_TOKEN --limit 1000

# Custom output file
python ci_analyzer.py --token YOUR_GITHUB_TOKEN --limit 500 --output my_analysis.json

Important: Make sure your GitHub token has repo and workflow permissions, otherwise you'll get 404 errors.

Parameters

Parameter Default Description
--token Required GitHub Personal Access Token
--limit 100 Number of CI runs to analyze
--output ci_analysis.json Output JSON file for detailed data

Getting GitHub Token

  1. Go to GitHub Settings > Personal Access Tokens
  2. Click "Generate new token" > "Generate new token (classic)"
  3. Important: Select the following permissions:
    • repo (Full control of private repositories) - Required for accessing repository data
    • workflow (Update GitHub Action workflows) - Required for reading CI/CD data
  4. Copy the generated token and use it as YOUR_GITHUB_TOKEN

Note: Without the repo and workflow permissions, the tool will not be able to access CI run data and will return 404 errors.

Output

The tool provides:

Console Output

  • Overall statistics (total runs, success rate, etc.)
  • Category failure breakdown
  • Most frequently failed jobs (Top 50) with direct CI links
  • Failure pattern analysis

JSON Export

Detailed analysis data including:

  • Complete failure statistics
  • Job failure counts
  • Workflow failure counts
  • Failure patterns
  • Recent failure details

CI Job Categories

The tool automatically categorizes CI jobs into:

  • sgl-kernel: Kernel-related tests (build, unit tests, MLA tests)
  • unit-test: Unit tests (frontend, backend with different GPU counts)
  • performance: Performance tests (latency, throughput benchmarks)
  • accuracy: Accuracy tests (model evaluation)
  • deepep: DeepEP-related tests
  • b200: B200 hardware-specific tests

Failure Patterns

The tool recognizes these failure patterns:

  • Timeout: Step execution timeout
  • Unit Test Failure: Unit test execution failures
  • Performance Test Failure: Performance benchmark failures
  • Accuracy Test Failure: Model accuracy evaluation failures
  • Build Failure: Compilation/build process failures
  • Dependency Installation Failure: Package installation issues
  • GPU Related Failure: GPU-specific test failures
  • Other: Unclassified failures

Troubleshooting

Common Issues

  1. 404 Error:
    • Ensure the repository name is correct (sgl-project/sglang)
    • Most common cause: Missing repo or workflow permissions in your GitHub token
    • Go to GitHub Settings > Personal Access Tokens and regenerate with correct permissions
  2. 403 Error: Check that your GitHub token has the correct permissions (repo and workflow)
  3. Rate Limiting: The tool includes built-in delays to avoid API rate limits
  4. Network Issues: Ensure stable internet connection

Debug Mode

For detailed API call information, you can modify the code to include logging:

import logging
logging.basicConfig(level=logging.DEBUG)

Automated Monitoring

The CI monitor is also available as a GitHub Actions workflow that runs automatically every 6 hours. The workflow:

  • Analyzes the last 500 CI runs
  • Generates detailed reports
  • Uploads analysis results as artifacts

Workflow Configuration

The workflow is located at .github/workflows/ci-monitor.yml and uses the GH_PAT_FOR_NIGHTLY_CI secret for GitHub API access.

Manual Trigger

You can manually trigger the workflow from the GitHub Actions tab with custom parameters:

  • limit: Number of CI runs to analyze (default: 500)
