Quick Summary: Observability is a proactive method to identify and address issues at their core, enhancing the reliability and performance of IT systems. In this article, we will explore the concept of observability, examining its three types, benefits, and challenges, supplemented by real-time examples for a clearer understanding.
What is Observability?
O Understanding observability is akin to a routine health check-up for your software system. Just as a doctor examines vital signs, blood tests, and diagnostic tools to assess a patient's health, observability involves collecting and analyzing logs, metrics, and traces to evaluate the well-being of your software.
In other words, observability refers to the degree to which you can deduce the inner workings or status of a complex system solely by examining its external results. The higher the level of observability a system possesses, the more swiftly and precisely you can trace the origins of a performance issue once it's identified, without requiring additional testing or coding.
This article discusses the three types of observability - infrastructure, data, and machine learning. It covers critical components, tools, and real-time examples. These terms are not unique to our technical personas like DevOps teams, data engineers and MLOps engineers. In this article we will discuss what Observability means to all these engineers.

Infrastructure or System Observability (Full-stack visibility inside infrastructure)
This observability primarily focuses on latency, failure, and resource utilization. It entails measuring the real-time state of an IT environment through data generated in the form of logs, metrics, and traces. By collecting and analysing these data points, it provides insights into the system's performance, health, and behaviour, enabling informed decision-making and troubleshooting.
Software engineers possess the capability to efficiently monitor distributed IT systems, granting them full-stack visibility into the infrastructure. This proficiency enables them to identify cascading effects within complex systems and conduct root cause analysis with the utmost precision.
Key Components of Infrastructure Observability
Instrumentation:
Instrumentation lays as a foundation step for observability. This component refers to the use of specialized measuring tools or software components that enable you to gather telemetry data from various sources within an IT environment. These sources can include containers, services, applications, hosts, pods, and more. It is essential in providing valuable insights that are crucial for monitoring, troubleshooting, and optimizing your infrastructure.
Data Corelation:
This component helps in connecting the dots from the telemetry data to identify patterns, trends and potential relationships in the IT ecosystem. This correlation is essential in diagnosing the issues and make informed decisions. By facilitating automated data curation and streamlining the process of organizing and visualising time series data, it becomes easy to scrutinise the performance history of the system.
Incident Response:
This is a key aspect in managing IT systems. It delivers the timely information regarding data outages. This demands technical skills and expertise from the incident resolution team.

After having a fresh data, next step is data distribution. Data accuracy is the most essential element when it comes to reliability. Data distribution provides insights into the system's data variability. Excessive variance indicates potential accuracy issues. This aspect of data distribution centres on evaluating the quality and consistency of data generated and consumed by the system.
Volume:
The data volume seeks to address whether incoming data adheres to predefined threshold limits or if sufficient storage capacity is available to accommodate the data needs. Maintaining ongoing vigilance over data volume guarantees that data requirements remain within established boundaries.
Schema:
As an organization expands and new features are incorporated into its application database, the database schema, which defines the structure of the database, may need to be altered. The schema serves as a blueprint for organizing data, specifying the arrangement of data tables, the attributes of fields, and the names of columns.
Lineage:
Lineage refers to the ability to trace and understand how data flows through various components and systems in our organization. It involves tracking the origin, transformations, and destinations of data. To fully grasp the data ecosystem, you need to consider four key aspects or "pillars." These pillars represent different elements of data management, such as data quality, data governance, data integration, and data security.

Machine Learning Observability (Full-stack visibility inside training model)
Machine learning capability examines the performance of models, measuring how well they can predict the systems. Machine learning engineers and data scientists employ ML observability to gain a deeper understanding of the model's evolution throughout its development stages.
Key Components of ML Observability
Performance Analysis:
Consistency in performance is vital. Therefore, this aspect ensures that the performance of machine learning models remain consistent. It assesses whether the model's performance in real-world deployment or usage aligns with its behaviour during the training phase.
Drift:
Drift detection helps determine whether a machine learning model is still valid and relevant. It identifies changes in the data distribution, indicating if the model has become "stale" or if data quality issues or adversarial inputs are affecting its performance. Detecting drift is crucial for safeguarding the model from degradation and ensuring it remains reliable.
Data Quality:
Data quality focuses on identifying issues within the data pipelines, specifically between the training and production phases. It aims to catch issues like missing data or data type mismatches, which can have a detrimental impact on system performance. Monitoring data quality is essential for maintaining the integrity of the model's input data.
Explainability:
It reveals the features used during training, validation, and production that elucidate the model's behaviour. Measuring this can be done through the calculation of metrics such as SHAP and LIME.
