When we're working in a developmentĮnvironment, it's easier to look into errors. We've just released a product, and everything works perfectly.Īt least that's what we think until we start seeing user reports about theĪpplication's performance and users running into errors. That regularly makes a few requests to imitate traffic on the applications. bin/traffic) running in the background together with the server Our small blogging platform also already has some active users.

We have a Post model, PostsController, and all CRUD actions exposed via the /posts route. The application we're working with is very minimal, so there are only a few things to note. Once it is complete, it will start the Rails When you run this for the first time, it may take a while to build the docker images andĭownload all the dependencies. $ git clone -branch appsignal-setup/start-docker -single-branch appsignal-setup $ cd appsignal-setup $ yarn start:compose Run the following commands to clone the repository, install dependencies, and run the application: We will use a sample application to get us started and run it on Restart/redeploy your application as you usually would.
