Monitoring applications

Stackdriver can monitor standalone applications by capturing metrics and logs. It has support for major platforms and libraries, so our technology choices should not be a concern. In this case, we are going to create a Node.js application for several reasons:

• It is easy to understand
• The official examples are well documented for the Node.js version
• Node.js is increasingly becoming a big platform for enterprise and startups

npm init

Follow the instructions on the screen and you should now have package.json in the folder that you just created. Now it is time to install the dependencies:

npm install --save ...
