The term “error log” is used in the field of computer science to describe the record of critical errors that the application, operating system, or server encounters during its operation. For example, a well-known error log entry that appears more often than not is that of a corrupted table or a corrupted configuration. In many cases, error logs can be handy when working on troubleshooting and managing systems, servers, and even entire networks, thanks to the information they contain.
How are Error Logs Used?
To troubleshoot a website, web admins frequently use log files. Whenever an error occurs, they will use the log to reproduce the event, figure out the problem, and develop a solution to fix it. Likewise, engineers and technicians who work with hardware often keep logs so that they can address malfunctioning equipment and prevent them from happening again.
An analysis of the error logs by security operations professionals is an integral part of identifying and reviewing hacking attempts related to software errors. Professionals in external departments can also access error logs through third-party applications to manage projects and report on their work.
What Do Error Logs Contain?
A log file may contain errors logged by an application in one of two ways: either unhandled error messages or custom error messages. Messages that are not handled by a system are also referred to as untrapped messages. Developers do not take untrapped notes in their code as the developer does not understand how to manage them. Libraries or runtimes of an application can throw errors at times.
However, the exception handlers implemented in the program code log custom error messages as they occur. Developers have anticipated these error conditions and have written code to handle them in advance. The message will likely be more human-readable if the user attempts to withdraw more than the current balance from a banking application.
Benefits of Using Error Logs
The following are some of the benefits of using it:
Improved Resolution Times
Incorporating error logs into a modern log management system will reduce your IT environment’s mean-time-to-resolution (MTTR), which helps you reduce the cost and time associated with solving problems. In addition, you can filter, search and find errors you are interested in with these log management solutions, drill down and identify the exact field values that are causing the errors, correlate events across multiple logs of mistakes, and predict other possible issues in the future. This can lead to proactive measures that will reduce the likelihood of downtimes by taking all the above steps.
Decision-making made easier
A wide range of log management solutions feature dashboards, trend charts, the top N errors by importance, and various reports that can help you identify which errors are critical to identifying and whether they should be scrutinized immediately. Also, patterns found in the error logs can help teams find hidden problems and take proactive steps to resolve them as soon as possible, thereby preventing customer complaints from occurring in the first place.
A higher level of performance
It is possible to identify performance issues in an application by reviewing the error logs. For example, it is possible to determine whether your application hangs, has memory problems, or is not performing well. In addition, it is beneficial to analyze logs over time to identify common reasons for performance bottlenecks.
