At least one Java log framework must be in place in order to facilitate logging, providing objects, methods and configuration settings necessary for sending log messages and creating log entries.
There are numerous logging frameworks and libraries available - some popular examples being Log4j and Logback.
Before choosing a log tool, you must choose an ideal framework. Log4j makes an excellent option and should meet most people's requirements.
Data reigns supreme in today's fast-paced business world. To effectively manage data efficiently, an effective process for tracking and reporting must be put in place.
We will explore all aspects involved with creating such an efficient workflow so your organization can leverage all its assets efficiently.
Reporting And Logging Are Crucial
Let's first consider why reporting and logging are vitally important to any successful company's operations.
Imagine your organization as being lost at sea; reporting and logging provide essential tools that allow it to navigate safely along its course and avoid potential obstacles along its journey.
Decide Your Aims And Create The Sailing Course: Define Your Objectives
Every trip and organization has differing data needs and requirements, which makes establishing an efficient logging and reporting process important.
You must first clearly establish your goals with regard to what data collection efforts they wish for; such as monitoring sales figures, gathering customer reviews or tracking website traffic data - before setting an achievable logging and report process in motion. Clarifying goals early is vital.
Data Collection: Mapping Routes
After you have established your goals, the next step should be figuring out a method for collecting data.
You may require setting up tracking tools on site or installing analytics in production lines - anything to ensure the data gathered meets with objectives set. It is crucial that collected information be timely, relevant and accurate if it's to meet the objectives set.
Data Storage And Administration
Finding an efficient means of storing and organizing data securely requires finding an approachable database or cloud solution with robust security provisions that are also easily accessible for access.
Data Analysis: Mapping Out Your Path
Data alone can seem like an endless sea of numbers until it has been properly analyzed.
Leverage the various methods and tools available for data analysis to gain valuable insight from this sea of numbers; from running complex algorithms to producing customized reports - anything goes! Converting raw data to useful knowledge.
Reporting: Weathering The Storm
Your data insights become actionable only when they're reported, which should be concise and easy for recipients to comprehend.
Reports must reflect who the intended recipients of these insights may be - this might include executives, engineers or marketing teams. Graphs or charts may make data easier for others to digest.
Monitoring And Feedback
Successful log and report processes should be flexible enough to adapt to changing user needs, gathering feedback continuously from your data users.
Be vigilant of new sources that need consideration as well as any goals shifting or shifting within your business that require adjustment in course direction; be open-minded enough to alter course if necessary.

Benefits Of Logging And Reporting
A properly executed log management and reporting process can bring many advantages; here are just a few benefits:
- Making Informed Decisions: Your organization can benefit immensely from having access to real-time data and insightful reports that enable it to make timely decisions, whether that means making adjustments to marketing strategy or streamlining production processes. Data will lead to greater success, whether that means revamping marketing tactics or optimizing production processes.
- Increased Efficiency: A structured process reduces guesswork. Teams can access needed information at their convenience, saving both resources and time in wasted efforts.
- Accountability is enhanced. Logging and reports create an atmosphere of openness where accountability and responsibility can easily be identified; when team members can easily track their progress, they're more likely to achieve their goals.
- Recognizing Trends Over time, you will start to detect patterns that have previously passed you by. This information can prove invaluable in creating long-term strategies and plans.
- Competitive Edge In today's highly competitive environment, organizations that leverage data have an edge. Utilizing logs and reports, you can keep tabs on market changes quickly.
Test Logging
The Benefits of Logging.
- Carefully review the execution history of your test.
- Logs that document the results of your tests.
- Logs save both time and energy. A reliable log can save time for both parties involved.
- Logging solutions have an integral part to play in every project.
No logs mean no way of debugging and understanding what's happening; as such, we will spend much more time than necessary manually debugging our systems and analyzing what they show us.
This delay also gives time for us to determine whether the issue is truly an error or just some strange event that needs our attention.
This Approach Presents Several Drawbacks
- Concatenating strings may cause errors that cause the test to crash with a NullPointerException error message.
- No levels of detail exist, and the execution of this project is taking longer than planned.
- No need to format text.
- There is typically a standard approach to log management used in development environments:
This example showcases the LogBack Library. LogBack has quickly become the industry standard in LogBack applications, and this library can be found across most Java applications.
This approach is straightforward. Simply create a log, name it and output either an error or informational message depending on its level of log.
MDC provides another means of recording codes. Every log message will include this label; simply add one before commencing with your run.
Filtering log messages can be of immense assistance in managing test types accurately.
Filters provide the freedom and control needed for efficient results analysis. Add whatever details are relevant - such as a name for the suite, an identifier to identify your startup or even a username - by editing this text field.
Logging as much data as possible while still making it easily accessible is the ideal overall practice.
Unfortunately, this task can be time-consuming, so to achieve larger goals, you must follow several best practices - here are a few:
- Severity levels. Setting log severity levels helps increase the readability of logs and prevent you from missing important ones while simultaneously keeping an eye out for any problems in your application that aren't immediately evident due to being blended in with other logs. You have five log severity options you can utilize: Debug/Verbose for errors; Info for events that could potentially impact users; Warning (for issues requiring further investigation); Critical/Fatal.
- Clarifying Log Data. Logs should be written, taking into account that they will not just be read by yourself. Make sure they can easily be parsed; in certain situations, it may even be necessary to print two logs for computers and one for humans.
- Add Metadata. Including metadata can help pinpoint problems in production by making your log more valuable, providing key clues on where an error's source lies. Class, Category and Method IDs provide excellent ways of quickly pinpointing where problems exist in real life.
- Consider Log Size. Creating logs that are too large is best avoided as masking unneeded data or including information you don't require can reduce its value and could have serious ramifications on performance and bandwidth usage. While detailed logs can provide great detail and insight, avoid storing non-related data therein.
- Log exceptions correctly. Make sure that all exceptions are being properly reported without accidentally duplicating their reporting more than once by using an exception tracker solution to report on them and automate tools that can create alerts based on specific log types for more precise insights.
Tools For Log Management
Our DevOps framework required us to incorporate log management solutions, and there are currently two open-source offerings on the market.
- Gray Log
- Kibana
Elasticsearch utilizes both product data and Elasticsearch databases. Elasticsearch provides a distributed RESTful analytics and search engine, designed for multiple uses across many applications.
At its heart lies ElasticStack; Elasticsearch allows lightning-fast searches with high relevance while easily scaling with your data needs.
Elasticsearch's primary advantage is instant search. Logging frameworks typically come equipped with extensions designed to send all test data directly into Elasticsearch for analysis.
What are some advantages of sending logs directly into a database?
- These logs are not lost or erased.
- Accessible (View logs on the user interface accessible).
- Instant search (Thanks ElasticSearch)
Test Reporting
Reports provide an essential method of transmitting information between contractors/clients and customers.
They should contain details from prior stages' activities.
Reporting on tests involves providing details regarding all activities undertaken during their performance.
For instance, running test cases and errors detected, time spent etc.). A test report is an official document that details this work performed (running test cases or errors discovered, time spent etc) as well as results (failed/passed tests or mistakes and failures experienced during this testing phase etc).
Are test reports necessary? Absolutely, and for three primary reasons. Test reports provide us with an invaluable way to gauge the progress and quality of a project.
Corrective steps may need to be taken if required. Test reports can determine whether or not a product will be released to market.
Reports must be of superior quality and transparent for clients, serving as the ultimate measure of how we evaluate our work.
Who Is Accountable For Creating The Test Report?
As part of your report writing process, you must identify who the report will benefit and who will read it.
With that information in mind, decide the topics and information for inclusion based on who will read your document and their priorities.
Target audiences include three distinct audiences.
Technical Users (Test Managers): They focus on understanding the test process, from issues arising and being addressed through to designing processes as well as technologies and methodologies being utilized.
Focus areas include timing of implementation, net test results without unnecessary technical details and general statistics (digital indicators and comparative measures).
Product Owners (Business Users): These individuals make final decisions after testing, as well as determine the level of quality in work completed.
They place great weight on receiving results presented clearly and quickly (such as "Yes or No"), as this final answer can have lasting impacts on businesses and users.
Expertise regarding the production possibilities of a product within its industry environment should be provided visually through graphs and charts, along with expert assessment as to whether a release can take place without going into much depth.
Attaining success when producing reports requires targeting specific audiences. Therefore, before creating the test report, you must identify your primary audience.
Content structure will differ depending on the audience being addressed and may include different details.
As part of my work, I often utilize the Allure Framework.\ Allure Framework, a lightweight yet flexible multilingual testing report generator, allows users to maximize the value of everyday tests by presenting them attractively on the web.
The Allure Framework by qameta.io can be used to obtain reports about automation script progress.
Reports provide data in an easily understandable format for testers as well as project managers; adding screenshots, logs and files provides further clarity for both audiences. Reporting via Allure makes complex tests simpler by breaking them into steps with relevant parameters or environments clearly displayed; reports may be generated using either console utility reports or plugins for project build and continuous integration systems (Allure has ready-made plugins available for Jenkins MSTests Maven PyTests Spock NUnit and Codeception for various programming languages).
As part of your user interface testing report, include complete details on any potential problems.
Include logs and screenshots where necessary in your report. Allure must know we want to gather data for attaching reports; for this, the Listener class needs to be created.
How To Establish An Effective Log Policy
Don't assume your situation is out of the ordinary: most companies wait too late before adopting any policy on logging.
Logging policies at any company must be consistent and reliable to guarantee access to key data - this investment provides great returns! Implementation of an enterprise-wide log policy entails three steps: creating the policy itself, communicating its adoption to all employees within your company and then enforcing it.
Establishing A Logging Policy
There are two guidelines you should abide by when developing a policy on logging.
- The less you do, the better
- Simple is best
Effective policies tend to be short, direct, and simple; otherwise, they risk becoming so complicated that people forget or overlook all their details.
Levels Of Logging
Logging involves two main parts - sending in entries and retrieving them - so when sending in log entries, the appropriate level and frequency must be specified for their upload.
Determining Storage Constraints
Companies that log typically want to record everything. Unfortunately, doing this unconstrained is risky because log files could take over all available disk space quickly.
There may be good reasons for keeping error information stored locally on a host machine, such as being easily available when needed for users when needed by them directly; in such a situation, a reasonable storage policy would include keeping error info within that machine in addition to recording all log levels through scalable logging systems; another aspect would include sending WARNING or ERROR log data directly into a repository to enable predictive analysis by users directly and without delay!
Determining Access And Notification Policies
Your company's operational requirements and security services policy will dictate how log data should be obtained.
Too much data may prove distractive; to achieve optimal performance, a notification policy must answer two simple questions about who gets informed and what about when.
Log data should never be ignored or treated like mere system information; rather, it requires an effective policy to secure its protection and ensure PCI DSS compliance is achieved.
You can ask similar questions of those working in IT Governance who strive for PCI DSS compliance to gain entry.
Communication Of A Logging Policy
Convincing employees to follow any policy is no simple matter, let alone something as vague and broad-brush as the one on logging.
For an effective policy on this matter to exist, its intention must first be understood clearly by all.
As part of your employee communication strategy for your Logging Policy, use an engaging message.
Repetition should occur after it has been developed; creative approaches could include publishing an IT Operations Intranet listicle entitled 7 Facts about Logging policy that will amaze friends and impress family; your head of department could even announce this message during weekly meetings.
Enforcement Of Logging Policy
Implementing a logging policy effectively is of utmost importance. To do this, you should automate as much of its implementation process as possible - for instance, by including it within programming language code such as Python decorators or Java annotations that create log events such as BeforeSave and AfterSave events automatically.
You could even develop plugins specifically targeted to each developer's Integrated Development Environment environment for use during development processes.
One technique would be to enlist someone in IT Operations as the Policy Wonk, responsible for supporting logging policies during DevOps review meetings or code reviews, as well as offering expert advice at department or team levels.
Tokens of appreciation can be an unexpectedly effective way to enforce policies.
The Build Breaker Trophy is more than just an amusing gag; it has proven its efficacy many times over. People value recognition; even though it might appear juvenile to give an award supporting a logging program, it works wonders.
Policy Wonks should err towards authoritarianism when fulfilling this role, encouraging other individuals and entities to adhere to current policy by setting an authoritative example, not acting as enforcers.
Encouraging compliance rather than giving in may help people stay within its confines longer term as non compliant individuals will revert to old ways more readily than complaisant individuals will.
Create A Logging Policy
A straightforward logging policy is one cost-effective method of improving log management within an organization.
However, to keep its impact going for as long as possible, changes must be implemented when necessary - the scope and technology surrounding logging will change regularly - thus, IT must adopt a culture devoted to log management while still having enough flexibility to adapt quickly to changing requirements.
