Top 5 Application Logging Best Practices to support your Analysis

Application logs are the lifeblood of IT, providing information about such things as how the software is performing, troubleshooting the application, and analyzing data that has been collected. Problematically, it is difficult to find out how to analyze logs and make sense of them. As such, many organizations are not taking advantage of the details that log data has to offer. On the whole, application logging is an important feature that helps to identify problems and can help in the debugging phase. Let us take a look at a few Best Practices for Application logging to make the best use of it.

What is Application Logging?

The process of logging application events is known as application logging. Tech experts can identify dangers and investigate faults using this information before they impair larger corporate operations.

Program logging differs from conventional event logs in IT systems in that the information it collects is defined by each specific application rather than the operating system.

We obtain deep insights into application logic and integrity, notably cross-component visibility, by considering logging as a key system component and employing techniques including unique IDs, transaction tracing, and structured log output.

Understanding how to evaluate the managing application logs and filter through the vast amount of data included in an application log can be daunting, but knowing how to do so can help professionals adapt to today’s fast-changing digital world.

What are the different types of application logging?

There are five types of application logs you should gather at a high level: Authentication, Authorization, and Access:  Successful and unsuccessful authentication and authorizations, system access, data access, and application access are all examples of these occurrences.

What is application level logging?

Application logging is an essential habit a developer may incorporate in their code to aid production support. Log entries provide crucial information such as a timestamp, relevant information, and notifications.

When anything goes wrong, the existence of logs in all settings enables for detailed tracking, alerting, and analysis.

Why is Application Logging Important?

Check out why application logging is important:

  • The scale and intricacy of your operations grow in tandem with the complexity of your processes and devices. One can spot trends throughout their entire company’s infrastructure using logging, allowing you to adjust early and devise solutions that extinguish accidents rather than having to put them out.
  • Application logging tools are globally used in situations :
    • Where they don’t have access to debugging tools
    • When debugging tools aren’t available, yet log messages can still be useful in locating problems.
  • Managers and network administrators supervise a large number of computers and ensure that they are operating as efficiently as feasible. They examine the logs to ensure that everything is functioning properly.
  • Any previously unknown communication, such as messages regarding overheated hard drives, lost deliveries, or logins outside typical business hours, is suspicious and requires attention.

Hence for all these reasons Application Logging plays an important role in our high standard management and feasibility of the operations.

Why is logging critical in IT security world?

In order to avoid, detect, or minimize the consequences of a data compromise, logging methods and the capacity to follow user actions are essential. When anything goes wrong, the existence of logs in all settings enables for detailed tracking, alerting, and analysis.

Top 5 Best Application Logging Practices

Logging is incredibly crucial in any application since it allows you to log a lot of important information and acquire unique insight into how your application works as well as performs. It’s a language/framework agnostic approach that it is urged that you begin practicing right now if you haven’t yet.

Here is a list of 5 best application logging practices one must be aware of:

Maintain a startand and easy configured Logging framework
  • A logging framework is a tool that helps you standardize the logging process in your application. A third-party tool, such as  log4net or  log4j, can help with this.
  • To be more explicit, a logging system may be imagined as encompassing three key concerns: recording, formatting, and adding. Seek for a logging framework with a straightforward, user-friendly API.
  • A reasonably novice team member should be able to take a look at an established popular usage or two and grasp how to utilize it on his own as a measurement tool. As a result, application logging that is simple and flexible is critical.
Always put into action fault-tolerant protocols
  • The fault-tolerance of the application loggings practices is critical. Fault-tolerant protocols are built to withstand errors. Demonstrating protocol fault resistance is a difficult topic because it mixes the parameterized setup on which distributed systems are built with the necessity to address a hostile context that causes the failures.
  • By making it fault-tolerant, we must first identify probable problems that a system may face and then create counter-measures.
  • To determine which mistakes a system should accept, the occurrence and effect on the system must be calculated.
Monitor the complete backlogs and outages
  • A backlog is a checklist of elements or ongoing maintenance that the team keeps track of and that are known to be essential and sufficient to complete a project or release at any given time.
  • Backlogs, as they’re known in the business, may grow extensive and unmanageable, and the pressures of digital transformation, along with the ongoing skills shortage, exacerbates the situation.
  • Monitoring of application logging practices backlog and outages can help in smooth functioning.
Always Encrypt data in transit
  • At rest, in use, or in transit, data can be encrypted in one of three ways. When you send an email, surf the Internet, or upload documents to the cloud, encryption in transit secures your data while it travels from one site to another. Interception, access, and transformation are all more difficult.
  • SSL encryption protects data as it passes between a web server and your browser. Any data you send to that website without SSL protection might be intercepted in route.
Keep requirements of the IT department upfront
  • There are people committed to IT security in various areas. These experts also deal with logs and analyze them in a variety of ways. Their reports cover everything from authentication to resource access to malware activity, allowing them to identify and respond to security issues.
  • Log messages are a very helpful tool for a wide range of IT activities, but merely collecting logs locally in text files is sometimes insufficient. Even if the source system has a hardware failure or logs have been erased following a security event, central log collecting allows you to immediately verify log messages.
  •  DevOps is a new IT trend in which a developer and an operator work together to ensure that custom-developed systems execute properly.

Although increased logging may down raw runtime execution by 5% to 10%, the precise information provided in a single searchable area allows us to detect problems considerably faster, allowing us to respond to incidents faster.
