“Isn’t observability just a fancy term for monitoring?” That’d be the response from most IT folks a few years back if you asked them about it. And here we are in 2023, where Observability now is as imperative a term as security itself.

Observability, as a concept in software engineering and system monitoring, has met with its share of criticisms – complexity, cost concerns, data overload, integration challenges, and skill gaps are a few concerns associated with observability. Despite these challenges, today it has become an integral part of software deployment.

In this extensive guide, we’ll dive deep into the world of Observability. Exploring what is observability, along with its history, importance, benefits, and challenges. We’ll also explore how Apica is transforming the observability space with its Operational Data Fabric architecture and most recently with its Generative AI integration.

What is Observability?

“Observability is not the microscope. It’s the clarity of the slide under the microscope.”

Observability is generally about how well you can figure out what’s happening inside a system by looking at what it’s showing on the outside.

Put simply, observability is all about knowing what’s going on inside your code or system just by using your tools to ask the right questions. Think of it like the dashboard in a car. The dashboard has features that let you see how the car is doing – like its speed, RPM, temperature, etc.

In the IT cloud landscape, observability refers to the capability of assessing the status of a system through the analysis of the data it produces, most notably but not limited to logs, metrics, and traces.

In recent years, the scope of observability data has widened. From today’s complex distributed system’s standards, it ought to include additional metrics like metadata, user behavior, topology, and network mapping.

What’s the difference between Monitoring and Observability?

In the realm of IT software development and operations, the concepts of monitoring and observability are often conflated. The gist of the matter is that they are complementary to each other albeit with distinct technical functions.

Monitoring is a more traditional approach, characterized by its reliance on predefined metrics and logs. The core assumption in monitoring is the ability to anticipate potential problems based on historical data and experience, setting up systems to alert when these predefined conditions are met. This approach works well in more static and predictable environments but encounters limitations in more dynamic contexts.

Observability, on the other hand, represents a more holistic and nuanced approach, particularly essential in the context of complex, cloud-native platforms. Unlike monitoring, observability doesn’t solely rely on predefined metrics or known issues. Instead, it focuses on the collection and analysis of a wide array of data (including metrics, logs, traces, etc.) to provide a comprehensive understanding of the system’s state. This approach allows for the identification and diagnosis of unforeseen or complex issues that arise due to the intricate interactions within distributed, cloud-native applications.

In essence, while monitoring is about keeping an eye on known quantities and expected issues, observability delves deeper, providing insights into the unknown and unexpected. Observability’s strength lies in its ability to make the internal states of systems understandable and diagnosable, even when facing novel or complex problems that were not anticipated.

History of Observability

The fascinating history of observability in computing is a journey that traces back to concepts in control theory and evolves alongside technological advancements.

  • Origins in Control Theory (1950s): The term “observability” was initially introduced by Rudolf E. Kálmán in 1959. Kálmán, a Hungarian-American scientist, wasn’t focused on computing but on broader system theory and signal processing. His work laid the groundwork for understanding how the internal state of a system can be inferred from its outputs, a principle that would later become pivotal in computing.
  • Early Application in Computing (1990s): While observability remained primarily within signal processing and systems theory, it began to see applications in computing by the late 1990s. At Sun Microsystems, for instance, observability was considered essential for performance management and capacity planning. This perspective differed from the modern view, where observability encompasses a broader role, including application performance management (APM).
  • Rise in the Computing Domain (2010s): The concept of observability gained significant traction in the field of computing in the mid-2010s. A notable development was a blog post from Twitter’s Observability Engineering Team in 2013, highlighting the use of observability in monitoring, alerting, distributed tracing, and log aggregation. This period marked the transition of observability into a mainstream concept in computing, frequently discussed in industry conferences and publications by early 2018.

Fast forward to today, observability is ubiquitous in the IT and cloud landscape. A 2021 survey by Enterprise Strategy Group highlighted the growing recognition of observability’s importance in IT, with almost 90% of IT leaders expecting it to become a critical aspect in the coming years.
