If you’re using Porter Cloud to manage your deployments, you can easily integrate with Subtrace to monitor your app’s network requests. Depending on how you build your app on Porter, the instructions are different.

We’ll use a Next.js app as an example, but you can do this with any language and framework.

Make the following changes to your app’s Dockerfile:

- CMD ["npm", "run", "start"]
+ RUN curl -fsSLO "https://subtrace.dev/download/latest/$(uname -s)/$(uname -m)/subtrace" && chmod +x ./subtrace
+ CMD ["./subtrace", "run", "--", "npm", "run", "start"]

Get a SUBTRACE_TOKEN from the Tokens page on the dashboard and set it as an environment secret on Porter:

Click the lock icon on the right to make it a secret.

And then deploy your app as you normally would.

That’s it! You can now visit your app and make some requests to see them automatically appear in the Subtrace dashboard.
