4 Tips For Logging in Java

Did you realize there are over 9 million Java programmers in the world? When using this programming language, developers are able to build apps that are both appealing and functional. Learning how to unlock the power of Java will take a lot of time and effort in java test.

One of the main things developers have to do when trying to catch problems and errors within their Java code is to learn to capture and analyze log files. With this information, you can optimize your app before it is put into the hands of consumers.

The following are some helpful tips for logging in Java.

1. Getting Familiar With Logging Levels

Most newcomers to the world of Java fail to realize there are several levels of logging. Here are some of the most common logging levels and what they mean.

  • Debug- During development and testing, debug is used to catch issues. It is considered the lowest Java logging level.
  • Info- This type of logging is a bit more restricted than debugging. However, it is strictly limited to information about outgoing or incoming messages.
  • Warning Message- Most head developers set warning messages to inform their team that an error is possible. When used correctly, these warning messages can help you prevent problems with your code.
  • Error- When trying to catch problems with exceptions, log errors are created. You will only see error messages when serious problems that can affect the overall functionality of your app are present.
  • Fatal- If a severe error that can make your app crash is detected, the fatal message will be triggered. Ignoring these severe warnings can lead to a lack of app functionality and reliability.

By familiarizing yourself with these various logging levels, you can make sense of the errors you are presented with during the development process.

2. You Need to Log Everything

The first step in handling an exception is using a try/catch. With the help of logging, you can backtrack and figure out the cause of the problems your app has. If you have no context for the errors you are being presented with, figuring out how to fix them will be impossible.

By logging everything, you can see what object logged the error and which user created it. With this full picture view of the problem, solving it and moving forward will be a breeze.

With the help of Cloud logging - Cloud based log management & analysis by Papertrail, getting your app back on track will be easier than ever. Finding and using the latest log management tools is the only way to keep your apps glitch-free and functional.

3. Make Sure Logging Isn’t Causing Unwanted Side Effects

Is your app starting to slow down significantly? If so, one of the first things you need to check is the amount of logging it is doing. One of the most common side effects of too much logging is slower computing speeds.

The best way to fix this problem is by putting limits on the logging. Setting an upper limit of how many logs can be created in an hour can be helpful. By altering how logs are gathered, you can get the information you need without affecting your app in a negative way.

4. Choosing a Logging Pattern

Selecting the right way to format your logs can help you greatly when trying to keep track of errors. Ideally, you want your logs to include information like date and time. You may also want to include other information like the file name. With this information, you will be able to pinpoint the cause of the error and get it fixed in a hurry.

Don’t Ignore the Power of Logging

Newcomers to the world of Java usually fail to realize the importance of logging. The information from the logs is essential when trying to avoid providing consumers with an unreliable app.
