Monitoring as code enables toolchain governance

Synthetic monitoring is driven by engineers (developers, SREs, DevOps engineers, …) to gain visibility into how their systems perform. Toolchain governance, on the other hand, is the core theme of directors, central tools teams, and CTOs.

Monitoring workflows that are not developer-first lead to fragmentation across teams, both tool- and process-wise, and make collaboration harder to ultimately result in worse outcomes for the users of the systems being monitored. Monitoring setups defined and configured outside of source control are proving increasingly unsustainable due to the lack of accountability and transparency. The more dysfunctional this feedback loop is, the more key metrics such as MTTD and MTTR will suffer over the medium to long term.

Monitoring as code and its developer-first workflow solves the governance issue.

The same tool for testing and monitoring

Programmatically define your monitoring setup and use the same resources for testing and monitoring to avoid yet another tool in your toolchain.

api.check.ts
new ApiCheck("public-stats-endpoint", {
  name: "API: Public stats",
  alertChannels: [],
  degradedResponseTime: 10000,
  maxResponseTime: 20000,
  frequency: Frequency.EVERY_30S,
  request: {
    url: "https://api.checklyhq.com/public-stats",
    method: "GET",
    followRedirects: true,
    skipSSL: false,
    assertions: [
      AssertionBuilder.statusCode().equals(200),
      AssertionBuilder.jsonBody("$.apiCheckResults").greaterThan(5000_000_000),
    ],
  },
  setupScript: {
    entrypoint: path.join(__dirname, "setup.ts"),
  },
  tearDownScript: {
    entrypoint: path.join(__dirname, "teardown.ts"),
  },
});
