Azure Functions

Learn about using Sentry with Azure Functions.

Sentry captures data by using an SDK within your application’s runtime. This means that you have to add @sentry/node as a runtime dependency to your application:

Copied
npm install --save @sentry/node @sentry/profiling-node

To set up Sentry error logging for an Azure Function:

Copied
const Sentry = require("@sentry/node");
const { nodeProfilingIntegration } = require("@sentry/profiling-node");

Sentry.init({
  dsn: "https://examplePublicKey@o0.ingest.sentry.io/0",
  integrations: [
    nodeProfilingIntegration(),
  ],

  // Add Performance Monitoring by setting tracesSampleRate
  // Set tracesSampleRate to 1.0 to capture 100% of transactions
  // We recommend adjusting this value in production
  tracesSampleRate: 1.0,

  // Set sampling rate for profiling - this is relative to tracesSampleRate
  profilesSampleRate: 1.0,
});

module.exports = async function (context, req) {
  try {
    await notExistFunction();
  } catch (e) {
    Sentry.withScope((scope) => {
      scope.setSDKProcessingMetadata({ request: req });
      Sentry.captureException(e);
    });
    await Sentry.flush(2000);
  }

  context.res = {
    status: 200,
    body: "Hello from Azure Cloud Function!",
  };
};

You can obtain the DSN using your Sentry account from your organization's Settings > Projects > Client Keys (DSN) in the Sentry web UI.

Note: You need to call both captureException and flush for captured events to be successfully delivered to Sentry.

Check out Sentry's Azure sample apps for detailed examples. Refer to the JavaScript docs for more configuration options.
