How Does Structured Logging Help You Debug Faster

When debugging an application issue, getting as much information as possible about what happened is essential. If you can see the entire sequence of events that led up to the bug, you’ll have a better chance of identifying what went wrong and coming up with a solution.

Structured logging can help you do this by providing a central place for storing data about an event. This includes not just text messages or numbers but also timestamps and other metadata such as user IDs or IP addresses.

Using structured logging in your app allows you to search across different lines in your logs to find similar problems and identify trends in your data so that they can be addressed before they become major issues later on down the road.”

What is Structured Logging?

Structured logging is a new way of logging that makes it easier to search and analyze your logs. With structured logging, you can do things like:

  • Search your logs
  • Aggregate information across different log lines

It’s very similar to what we’re used to with unstructured text-based logs. Structured logging adds some additional information that makes it easier for you to ask questions about the data in your logs.

Some of the key advantages that facilitate quicker debugging are:

  • Better integration – Applications may consume the data for downstream operations like dashboards or analysis by utilizing a uniform JSON format.
  • Better search – By using the JSON format, we can make queries on fields without depending on fragile regex patterns of raw text.
  • Better readability – System administrators and other log consumers using a standard format may process data more efficiently than when reading raw text files.
  • Structured logging is not just logging to log files. It’s also logging directly to a central database.
  • Structured logging lets you search your logs and aggregate information across different log lines.

Imagine a scenario where a user has put in an incorrect username or password to log in to the application. You can use structured logging to detect this error, which will help you debug faster.

You can use structured logging to get a new view of your data and see things you couldn’t before.

For example, let’s say you have an application that uses a database. Your team wants to create new features, but the existing code base is too complex and poorly structured. The developers are spending more time debugging than they are writing new code.

To fix this situation, we recommend that the team first use structured logging to get a new view of their data, then change how they access it to fix any bugs that arise from using this new info.

Structured Logging Lets You Write Better Debugging Tools.

When you use structured logging, you’ll be able to write debugging tools that are more accurate, easier to maintain, and user-friendly. Structured logging also makes it easier to write better debugging tools. And these are some of the most important features of a good debugging tool:

  • Accuracy: Your logging code should record every detail of an error. If it doesn’t, when someone looks at the logs, they won’t know exactly what went wrong or where in their codebase it happened (which can make tracking down bugs take longer).
  • Ease of Maintenance: A good debugging tool will allow you to add new information as needed without going through all your existing logs and changing them manually. This is especially useful if you’re writing in a language like JavaScript, where there’s no built-in support for structured logging yet.

Structured Logging Has Some Downsides As Well.

Structured logging has some downsides as well. Structured logging is more expensive because it requires you to run a database and add extra code to your application. It’s also harder to implement and debug since you need a central database that stores your logs, making them accessible to your entire engineering team.

Structured Logging Helps you Debug Faster.

Structured logging is not just for log files. It’s not even about logging in at all.

Structured logging lets you search your logs and aggregate information across different log lines. This means you can find the most relevant information in your logs instead of manually sorting through them to find exactly what you need. It also lets you create dashboards with metrics such as KPIs (Key Performance Indicators) or custom charts based on specific periods or other factors (such as errors per second).

With structured logging, when something goes wrong in production, two key aspects stand out: speed and visibility into how things went wrong.


In conclusion, structured logging is a handy tool for debugging. It can help you find bugs faster and understand the impact of changes. We can track down problems more quickly than ever with structured logging. It’s not just a matter of convenience—structured logging makes it possible to build better tools for analyzing logs in ways that would be impossible without the data structure inherent in this kind of logging format.
