monitoring（monitoring 开发）

Checkly Monitoring

• Refer to docs for Checkly CLI v6.0.0 and above.
• Check the Checkly CLI output to figure out into which folder the setup was generated.
• Use the Checkly CLI reference documentation.
• Use the Checkly construct reference documentation.
• Import and / or require any constructs you need in your code, such as ApiCheck, BrowserCheck, or PlaywrightCheck from the checkly/constructs package.
• Always ground generated code and CLI commands against the official documentation and examples in this file.

Using the Checkly CLI

• Use npx checkly instead of installing the Checkly CLI globally.
• NEVER make up commands that do not exist.
• Use npm create checkly@latest to set up a new Checkly project via the CLI.

Project Structure

• checkly.config.ts - Mandatory global project and CLI configuration. We recommend using TypeScript.
• *.check.ts|js - TS / JS files that define the checks.
• *.spec.ts|js - TS / JS files that contain Playwright code for Browser and MultiStep checks.
• src/__checks__ - Default directory where all your checks are stored. Use this directory if it already exists, otherwise create a new directory for your checks.
• package.json - Standard NPM project manifest.

Here is an example directory tree of what that would look like:

. |-- checkly.config.ts |-- package.json -- src-- checks |-- alert-channels.ts |-- api-check.check.ts `-- homepage.spec.ts

The checkly.config.ts at the root of your project defines a range of defaults for all your checks.

import { defineConfig } from 'checkly'
import { Frequency } from 'checkly/constructs'

export default defineConfig({
  projectName: "Production Monitoring Suite",

    activated: true,

    playwrightConfig: {
      use: {
        baseURL: "https://app.example.com",
      },
    },
    browserChecks: {
      frequency: Frequency.EVERY_30M,
      testMatch: "**/__tests__/*.spec.ts",
    },

})

Check and Monitor Constructs

Parse and read further reference documentation when tasked with creating or managing any of the following Checkly constructs:

• API Checks - ApiCheck construct, assertions, and authentication setup scripts
• Browser Checks - BrowserCheck construct with Playwright test files
• Playwright Checks - PlaywrightCheck construct for multi-browser test suites
• MultiStep Checks - MultiStepCheck construct for complex user flows
• Uptime Monitors - TCP (TcpMonitor), URL (UrlMonitor), DNS (DnsMonitor), ICMP (IcmpMonitor), and Heartbeat monitors (HeartbeatMonitor)
• Check Groups - CheckGroupV2 construct for organizing checks
• Alert Channels - Email, Phone, and Slack alert channels
• Supporting Constructs - Status pages, dashboards, maintenance windows, and private locations

Testing and Debugging

• Test checks using the npx checkly test command. Pass environment variables with the -e flag, use --record to persist results, and use --verbose to see all errors.
