3 Ways to Make Sense of Errors and Logging
Log files and errors are among the most crucial tools that developers must try and utilize to determine the root cause of a problem. If you're like many developers, your method for recording and using logs and errors is quite simple. It is possible to send log output to a file or log aggregation program. You can notify users of the appearance of errors by sending email directly from your program, or using an error-monitoring product.
What's missing from these methods is something that is more complete, holistic and specific. The issue can be seen in two ways:
There's usually more noise than signals if you're relying solely on logs in order to identify or isolate and identify your errors, particularly when an error is thrown repeatedly, or if you're dealing log files from multiple servers
If your focus is on issues, whether you're sending emails to alert you of errors or using an error-monitoring program, that method eliminates all relevant logs from the photo but leaves you with the information you require to pinpoint the root cause.

In this article, I'll discuss three methods to help you find the meaning of your errors and logs:
Aggregation -
If your application is an application that runs on one server, locating all your logs won't be an problem for you. However, it's more likely that there are applications that are hosted on several servers to ensure availability, scalability , and redundancy which makes it harder to quickly (and easily and centrally) access errors and log information.
Tools are available to combine logs in a variety of format (assuming that you are able to access them ) This is a move in the right direction in light of the potential for multiple log files that are distinct, in addition to log retention and rotation problems.
The most effective solution is to create a system that combines logs and errors with the goal of development in mind. So, you can ensure you've collected all the information you need and then present it in a manner that is geared towards developers.
Error De-duplication:
While aggregation will ensure that all your errors and logs are able to will be consolidated in one central area, it can also result in a lot of noise that obscures the important insights within your logs.
Moving beyond gathering log statements, and towards getting quick insight from your logs and errors, is to implement strategies that reduce the number of errors and gives additional details that is tied to the specific event of the error, while not making you go through the endless flow of error-related statements within the log. Making individual errors first-class things to be concerned about instead of just an additional line in the log file, provides you with high-level visibility.
It also allows you to create efficient notification and resolution strategies that focus specifically on an error and, with the right tool, provides you a base that allows you to see only the log statements that are related to the error (rather than having to comb through the entire log to locate those that are relevant). All of this is an approach that cuts through all noise and concentrates your efforts on the things you are most concerned about.
Analysis
Although you may be able to connect your data and tie the log and error data, you remain with a long list of things your application has done (and did not do, hence it's the exceptions).
There are many issues to be addressed before we really say we've made sense of this massive data set such as determining the frequentity of errors, linking the errors of one server to techniques and processes on another and being able to look swiftly through this enormous dataset, or even simply being able to move to a specific date and time - all of these, and much more are a part of the process in order to fully comprehend the data available to you.
Although logs and errors are frequently crucial to identifying problems with applications however, making the most of them can be a challenge. If you're using an extremely targeted tool or are rolling an own approach, that you're either struggling to find the data you require when you require it, or trying to locate a needle the pile of needles (or better yet to say, a needle in the pile of needles).
Making effective error notification as well as error de-duplication or log aggregation as well as seamless integration of errors, and only the log entries that are relevant is a particularly difficult task.
Making it work requires a lot of custom development, or a mix of custom development over top of a system that provides only a portion of the solution, or perhaps using several solutions that only address a portion of the issue.
