As a developer, one of the most irritating things I face is that my attempts to implement good coding practices often renders my code broken and filled with bugs. It is quite the tragicomedy of code development, all in the effort to comply with the ecosystem of DevOps. The problem usually occurs when I try to configure tools I am not familiar with, only to result in my code base inevitably throwing errors or behaving unexpectedly. I thus end up barraging senior developers with Slack messages, and Google with endless searches in order to unravel the correct way of configuring these tools. Obviously if one follows the tooling docs to the letter, it should be simple, right? Wrong! More often than not, the documentation does not always address the specific use case you are trying to implement. Most typically, developers suffer through lots of easily-avoidable errors in the journey to become an expert on how to configure and implement that particular tool.
One example of a difficult tooling scenario is implementing a typical serverless monitoring tool. In order to collect even basic monitoring data, you often need to perform an excessive amount of in-code configuration. Usually, you are required to ‘wrap’ your code with the monitoring tool for monitoring to actually occur. Wrapping is the most popular way to integrate monitoring tools and collect basic data from your functions. However, this approach means you need to wrap numerous functions in order to successfully monitor an entire application.
Furthermore, in addition to the integration burden, configuring these tools can also prove tedious. It’s too complicated to expect, for example, a single simple-minded stooge like an unpaid intern, to wrap hundreds of functions and also expect him to do so successfully. No, there needs to be a more simple, less risky way of implementing monitoring for serverless applications.
Our team at Thundra realizes that this manual, labor-intensive approach simply isn’t efficient, and we’ve thus tried hard to design a monitoring tool which is easy and simple to use. Thundra offers its own serverless plug-in that allows automated wrapping to set up basic monitoring, along with automated instrumentation for more detailed monitoring. You don’t need to change your code base just to monitor your code. Finally, adding monitoring to your Lambda functions is actually easier than writing your Lambda functions. This is the way it should be!
Our previous blog showed you how our automated instrumentation (for detailed monitoring data) works, especially for Node.js. Now, let’s take a look at how automated wrapping is implemented. For now, we support automated wrapping for Node.js and Python functions.
