The present-day infrastructure flourishes in distributed environments. This is where Observability comes in. Observability refers to the measurement of the internal state of the system by examining the outputs. This blog covers an inclusive view of Observability, including its Objectives, Working processes, Tools, Best practices, Advantages and Disadvantages.
Over the past 20 years, IT teams have greatly relied on Application Performance Monitoring (APM) to track applications as it regularly samples the system data, which is generally known as telemetry. This APM is beneficial for inspecting and troubleshooting applications.
But as developments took place, organizations started choosing modern development practices – DevOps, agile development, continuous deployment, and microservices. As organizations increasingly endorse intricate, multi-layered, cloud-based infrastructure utilizing microservices, observability has become an important cornerstone. Achieving observability requires a significant boost in the volume and quality of the telemetry data, enabling the detailed records of every application user interface.
Observability vs Monitoring
Observability and monitoring are two key concepts used in DevOps, software engineering and system administration. Though they are related to each other, they are two different terms. To have a better understanding let’s take a look at their key differences.
Observability is the capacity to learn a system’s internal state by evaluating the data such as metrics, logs and traces. This is considered important because it provides greater control over complex systems.
Monitoring is a process used to collect, examine, and interpret data to detect performance, decrease the negative effects of a process or system, and enhance beneficial effects. It allows us to watch specific metrics. Generally, monitoring is essential for examining long-term trends, alerting and building dashboards.
Let us now trace the difference between Observability and Monitoring.
How can Observability be Achieved?
Observability can be attained through a blend of observability tools and platforms, enablingthe development team to identify the system issues and achieve the business goals. By inspecting all the inputs, observability provides a better understanding of the distributed system.
Moreover, the goal of observability are as follows
Identify and link effects in a complex chain

Objectives of Observability
Having understood the details of observability and its goal, let’s now take a glimpse at its objectives.
Business SuccessPerformance and system availability are crucial for business success, as non-availability and underperformance negatively impact customers, affecting user satisfaction and customer experience. In some cases, it can also lead to revenue loss, business failure, or even reputational damage.
According to the survey conducted by Cloud Native Observability Report 2023
In a complex environment, it is impossible to keep track of observations. Thus, identifying and correcting the system issues before they have a greater impact can help resolve performance issues.
Security and Compliance
Observability also plays an important role in ensuring businesses abide by their legal obligations to safeguard sensitive data against unauthorized access. To prevent data breaches, observability tools can be used from a security perspective.
The observability practices can lead to a profitable and revenue-growing business, thereby boosting user experience. There are various ways in which growth can be measured. For example – analytical data about customer behaviour can help us make strategic decisions.
How does Observability work?
Observability works on three primary sources of data, also called the three pillars of observability – logs, metrics and traces. By constantly gathering these types of data, the observability platforms can provide contextual information.
In brief, by working with the pillars of observability, the teams can easily identify and solve problems in real time.
Let us explore more about the three pillars of observability.
Logs are records of events that occur over time, containing detailed information. Generally, logs are easy to execute as software libraries and languages often have built-in functionalities. Mainly, developers are accountable for logging in code. In some cases, logs can be analytical or historical, providing context in operations management.
Constantly, the data is measured through numerical value and recounts the overall behaviour of a service. Observability metrics measure response time, CPU Capacity, error rates, peak load and latency. These key performance indicators
Detects events for unique activities
Generates alerts when necessary
Traces are considered information pathways that follow a unit of work. The source of an alert can be identified through traces, accurately showing where tracking system dependencies are occurring.
Best Practices in Observability
Organizations can achieve a high degree of observability if the best practices are followed. Delve deeper to learn more about the best practices in Observability.
Monitor the Right DataMonitoring the data is more important than collecting it, as it helps in achieving the business objectives effectively. The observability platform should be planned to filter data close to the source.
Alerts Only for Critical EventsNotifications can be created and configured to detect important events in the system. Developers can detect problems and fix them when something goes wrong. An observability tool like Middleware works effectively on critical early-stage problems.
Standardized Data Logging FormatDevOps teams can identify issues from the data produced by logging, and the root cause of the issue can also be detected. Therefore, by structuring logs, the data should be formatted to maximize its usage.
Automate as much as PossibleManual monitoring takes time and can sometimes be error-prone. To achieve observability, automation is the key and choosing automation to collect data, initiate remediation actions and detect anomalies would be the perfect choice.
Aggregated and Centralized DataTo attain observability, data must be gathered, stored and examined. A more comprehensive view can be achieved by aggregating data from various sources.
