API Monitoring

Monitor GitHub API

Get alerted when GitHub has issues that could affect your deployments, CI/CD pipelines, and development workflows.

Quick Setup

  • 1. Monitor https://api.github.com/zen for general API health
  • 2. Add authentication header if monitoring private repos or Actions API
  • 3. Set alerts to notify before GitHub's status page updates

Why Monitor GitHub?

GitHub is critical infrastructure for modern software development. When it goes down, your entire development workflow can stop.

CI/CD Pipeline Dependencies

GitHub Actions, webhooks, and integrations stop working during outages. Your deployments, tests, and automation all depend on GitHub being up.

Developer Productivity

Teams can't push code, review PRs, or merge changes during outages. Knowing about issues early helps you communicate with your team.

Third-Party Integrations

Many tools fetch data from GitHub's API—project management, code analysis, deployment platforms. Monitoring helps you understand cascading failures.

Recommended Endpoints to Monitor

Critical Recommended for all users
https://api.github.com/zen

Lightweight health check endpoint. Returns a random GitHub design philosophy. No authentication required, minimal rate limit impact.

High For CI/CD workflows
https://api.github.com/repos/{owner}/{repo}/actions/runs

Check GitHub Actions availability for your repository. Requires authentication. Replace {owner}/{repo} with your repo details.

Medium For API-heavy integrations
https://api.github.com/rate_limit

Check your current rate limit status. Useful if you have integrations that make frequent API calls. Requires authentication.

Optional For component-level monitoring
https://www.githubstatus.com/api/v2/status.json

GitHub's official status page API. Check overall status programmatically. No authentication required.

GitHub Services You Depend On

GitHub is not a single service—it's many components. Understanding which ones your workflow depends on helps you prioritize monitoring.

Git Operations

Push, pull, clone, fetch. Core git functionality that developers use constantly.

GitHub Actions

CI/CD workflows. Outages here stop your automated builds, tests, and deployments.

Webhooks

Event notifications to external services. Critical for integrations with Slack, Jira, deployment tools.

API Requests

REST and GraphQL APIs. Used by third-party tools, bots, and custom integrations.

GitHub Pages

Static site hosting. If you host documentation or landing pages here, monitor it separately.

GitHub Packages

Package registry (npm, Docker, etc.). Critical if you publish or install packages from GitHub.

GitHub Rate Limits & Authentication

GitHub has rate limits that affect how frequently you can monitor. Here's what you need to know:

Auth Type Rate Limit
Unauthenticated 60 requests/hour
Personal Access Token 5,000 requests/hour
GitHub App 5,000+ requests/hour

Monitoring Tip

If you're monitoring once per minute (60 checks/hour), you're right at the unauthenticated limit. Use a Personal Access Token to avoid rate limit errors that could look like outages.

Set Up GitHub Monitoring in UptimeSignal

1

Create a monitor

Go to app.uptimesignal.io and click "Create Monitor".

2

Enter the GitHub endpoint

Use https://api.github.com/zen for basic monitoring, or a specific endpoint for your workflow.

3

Add authentication (optional)

For authenticated endpoints, add a header: Authorization: Bearer YOUR_TOKEN

4

Set your check interval

1-minute checks catch issues quickly. GitHub issues are usually resolved within 15-30 minutes.

When GitHub Goes Down: Response Playbook

1. Verify the outage

Check githubstatus.com for official status. Your monitoring alert may arrive before their status page updates.

2. Notify your team

Alert developers that GitHub is having issues. This prevents confusion about why builds are failing or PRs aren't merging.

3. Pause deployments

If your deployment pipeline depends on GitHub, pause it until the outage is resolved. Avoid partial deployments or failed builds.

4. Work locally if needed

Developers can continue working with local git. Commits can be pushed once GitHub recovers. Consider having a local git mirror for critical repos.

5. Monitor recovery

Your UptimeSignal alert will notify you when GitHub is back. Verify a few operations manually before resuming full workflows.

Frequently Asked Questions

Why should I monitor GitHub API if GitHub has its own status page?

GitHub's status page is updated manually and can lag behind actual issues. External monitoring catches problems faster and alerts you proactively, rather than requiring you to check their status page.

Which GitHub endpoint should I monitor for general uptime?

Monitor https://api.github.com/zen for general API health. It's lightweight, doesn't require authentication, and has minimal rate limit impact.

How do I monitor GitHub Actions availability?

Monitor https://api.github.com/repos/{owner}/{repo}/actions/runs with authentication. Alternatively, monitor GitHub's status page API for the Actions component.

Will monitoring GitHub API hit rate limits?

Unauthenticated requests are limited to 60/hour—exactly one per minute. Use a Personal Access Token (5,000/hour) to avoid rate limit issues that could look like outages.

What should I do when GitHub is down?

Check githubstatus.com, notify your team, pause deployments, continue working locally if needed, and monitor for recovery. Have a playbook ready so you're not scrambling during an outage.
