How to Use Checkly for Research

Why Use Checkly for Research?

Research projects often require monitoring distributed systems, APIs, and web applications across different environments and geographic locations. Whether you're conducting performance studies, analyzing user experience patterns, or validating system behavior, you need reliable data collection that won't interfere with your research methodology.

Checkly solves this by letting you define monitoring checks as code using familiar tools like Playwright and TypeScript. You can deploy identical monitoring setups across multiple environments, collect consistent metrics from global locations, and version control your entire monitoring configuration. This approach eliminates the manual overhead of traditional monitoring tools while providing the reproducibility that research demands.

Unlike traditional monitoring platforms that lock you into GUI configurations, Checkly's code-first approach means your monitoring setup becomes part of your research documentation. You can peer-review monitoring logic, replicate studies exactly, and share your complete methodology with collaborators.

Getting Started with Checkly

Your research monitoring needs will determine how you structure your Checkly setup. Start by identifying what you need to monitor: API endpoints, user workflows, system performance, or third-party service dependencies.

Sign up for a Checkly account and install the CLI:

npm install -g checkly
checkly login

Initialize a new monitoring project in your research repository:

mkdir research-monitoring
cd research-monitoring
checkly init

This creates a TypeScript project structure with example checks. The key files you'll work with are:

• __checks__/ - Your monitoring checks
• checkly.config.ts - Global configuration
• package.json - Dependencies and scripts

For research purposes, you'll want to configure multiple environments. Edit checkly.config.ts:

import { defineConfig } from 'checkly'

export default defineConfig({
  projectName: 'Research Monitoring',
  logicalId: 'research-project',
  repoUrl: 'https://github.com/yourorg/research-monitoring',
  checks: {
    locations: ['us-east-1', 'eu-west-1', 'ap-southeast-1'],
    tags: ['research', 'production'],
    runtimeId: '2022.10',
    checkMatch: '**/__checks__/**/*.check.ts',
    browserChecks: {
      frequency: 60,
      testMatch: '**/__checks__/**/*.spec.ts',
    },
  },
  cli: {
    runLocation: 'eu-west-1',
    privateRunLocation: process.env.PRIVATE_LOCATION_SLUG,
  },
})

Step-by-Step Setup

1. Create API Monitoring Checks

Research often involves monitoring API endpoints for availability and performance. Create an API check at __checks__/api-performance.check.ts:

import { ApiCheck, AssertionBuilder } from 'checkly/constructs'

new ApiCheck('api-response-time', {
  name: 'API Response Time Research',
  request: {
    method: 'GET',
    url: 'https://your-research-api.com/v1/data',
    headers: {
      'Authorization': 'Bearer {{API_TOKEN}}',
      'User-Agent': 'Research-Monitor/1.0'
    },
    assertions: [
      AssertionBuilder.statusCode().equals(200),
      AssertionBuilder.responseTime().lessThan(2000),
      AssertionBuilder.jsonBody('$.results.length').greaterThan(0)
    ]
  },
  runParallel: true,
  locations: ['us-east-1', 'eu-west-1', 'ap-southeast-1'],
  tags: ['api', 'performance'],
  frequency: 30, // Check every 30 seconds for research
})

2. Monitor User Workflows with Browser Checks

For user experience research, create Playwright-based browser checks. Add __checks__/user-journey.spec.ts:

import { test, expect } from '@playwright/test'

test('User Registration Flow', async ({ page }) => {
  // Navigate to application
  await page.goto(process.env.APP_URL || 'https://your-app.com')
  
  // Measure page load time
  const startTime = Date.now()
  await page.waitForLoadState('networkidle')
  const loadTime = Date.now() - startTime
  
  // Log metrics for research analysis
  console.log(`Page load time: ${loadTime}ms`)
  
  // Test user registration
  await page.click('[data-testid="signup-button"]')
  await page.fill('[data-testid="email-input"]', 'research-user@example.com')
  await page.fill('[data-testid="password-input"]', 'SecurePass123!')
  
  // Measure form submission
  const submitStart = Date.now()
  await page.click('[data-testid="submit-button"]')
  await page.waitForSelector('[data-testid="success-message"]')
  const submitTime = Date.now() - submitStart
  
  console.log(`Registration time: ${submitTime}ms`)
  
  // Verify success
  await expect(page.locator('[data-testid="success-message"]')).toBeVisible()
})

3. Configure Environment Variables

Research often involves multiple environments. Set up environment-specific variables using Checkly's environment variable management:

checkly env set API_TOKEN your-api-token-here
checkly env set APP_URL https://staging.your-app.com
checkly env set RESEARCH_COHORT_ID cohort-2024-q1

For sensitive research data, use Checkly's encrypted environment variables to protect participant information and API credentials.

4. Deploy and Validate

Deploy your monitoring configuration:

npm run checkly:deploy

Verify your checks are running correctly:

checkly check list
checkly check run api-response-time --verbose

Monitor the dashboard to ensure data collection starts immediately. Check the "Check Results" section for initial metrics and any configuration issues.

5. Set Up Data Export

For research analysis, you'll need to export monitoring data. Configure webhooks to send results to your analysis pipeline:

// In checkly.config.ts
export default defineConfig({
  // ... other config
  alertChannels: [{
    webhook: {
      name: 'Research Data Webhook',
      url: 'https://your-research-pipeline.com/webhook',
      method: 'POST',
      template: 'custom',
      webhookType: 'WEBHOOK',
    }
  }],
})

Tips and Best Practices

Choose appropriate check frequencies based on your research methodology. High-frequency monitoring (every 30 seconds) provides detailed data but increases costs. For longitudinal studies, 5-10 minute intervals often provide sufficient granularity while managing expenses.

Leverage global locations strategically. If researching geographic performance differences, use locations that match your user base: us-east-1, us-west-1, eu-west-1, ap-southeast-1. Avoid unnecessary locations that don't serve your research questions but add costs.

Tag everything systematically. Use tags like experiment-a, control-group, week-1 to segment your data during analysis. This makes filtering results much easier when you're processing months of monitoring data.

Monitor your monitoring costs. Research projects can generate substantial monitoring data. Check your usage in the Checkly dashboard regularly. API checks are cheaper than browser checks, so prefer API monitoring when browser interaction isn't required for your research question.

Version control your entire setup. Keep your monitoring configuration in the same repository as your research code. This ensures reproducibility and makes it easy to correlate monitoring changes with experimental conditions.

Handle rate limits carefully. When monitoring APIs, respect rate limits to avoid skewing your research data. Add delays between requests and monitor for HTTP 429 responses that might indicate you're hitting limits.

Set up alerting for data gaps. Missing monitoring data can invalidate research results. Configure alerts for check failures that might indicate data collection issues rather than system problems you're studying.

When Checkly Isn't the Right Fit

Checkly works well for web-based research but has limitations for certain use cases. If you're monitoring mobile applications directly, you'll need mobile-specific monitoring tools since Checkly focuses on web browsers and APIs.

For research requiring custom metrics beyond response time and availability, you might need additional instrumentation. While Checkly can collect basic performance data, detailed application profiling requires APM tools like DataDog or New Relic.

Very high-frequency monitoring (sub-second intervals) isn't supported. If your research requires microsecond-level timing or real-time monitoring, consider specialized performance testing tools instead.

Budget constraints matter for long-term studies. Extended monitoring across multiple locations can become expensive. Calculate expected costs based on check frequency, number of locations, and study duration before committing to Checkly for large-scale research projects.

If your research environment doesn't support external monitoring (air-gapped networks, strict compliance requirements), Checkly's cloud-based approach won't work. Consider self-hosted monitoring solutions for these scenarios.

Conclusion

Checkly transforms research monitoring from a manual, error-prone process into a reproducible, code-based methodology. By defining your monitoring as TypeScript code, you ensure consistent data collection across environments while maintaining the documentation and version control practices that good research demands.

The combination of global monitoring locations, Playwright-based browser automation, and API checking provides comprehensive coverage for most web-based research scenarios. The ability to export data programmatically integrates well with research analysis pipelines and statistical software.

Start with simple API checks to validate your setup, then expand to browser-based monitoring as your research questions require more sophisticated user interaction testing. The investment in learning Checkly's code-first approach pays dividends in research reproducibility and collaboration.
