They automatically discover new sources of telemetry that might emerge within the system, such as a new API call to another software application. Observability platforms also use telemetry, but in a proactive way. The platform shows you the what, where and why of any event and what this could mean to application performance, guiding how DevOps teams perform application instrumentation, debugging and performance fixes. This way, they not only understand what’s in the system but how different elements relate to each other. DevOps, site reliability engineers (SREs), operations teams and IT staff can correlate the gathered telemetry in real-time to get a complete view of application performance. They also identify and document dependencies, which reveal how each application component is dependent on other components, applications and IT resources.Īn observability platform takes monitoring a step further. When monitoring, teams use this telemetry data to internally define the metrics and create preconfigured dashboards and notifications.

Traces: How operations move throughout a system, from one node to another.

Metrics : A numerical assessment of application performance and resource utilization.

Logs: A record of what’s happening within your software.

The three pillars of observability are as follows: Both use the same type of telemetry data, known as the three pillars of observability. At its most basic, monitoring is reactive, and observability is proactive. observability, the difference hinges upon identifying the problems you know will happen and having a way to anticipate the problems that might happen. If your team hasn’t predicted a problem, it can miss key production failures and other issues. For monitoring to work, you have to know what metrics and logs to track. Monitoring helps teams watch the system’s performance and detect known failures however, monitoring has its limitations. It shows you not only how the app is functioning, but also how it’s being used over time. Where monitoring truly shows its value is in analyzing long-term trends and alerting. In DevOps, monitoring measures the health of the application, such as creating a rule that alerts when the app is nearing 100% disk usage, helping prevent downtime. Monitoring is the task of assessing the health of a system by collecting and analyzing aggregate data from IT systems based on a predefined set of metrics and logs. The result? It allows teams to detect problems proactively and resolve issues faster. An observable system is one where DevOps teams can see the entire IT environment with context and understanding of interdependencies.

In IT, an observability solution analyzes output data, provides an assessment of the system’s health and offers actionable insights for addressing the problem. For example, car diagnostic systems offer observability for mechanics, giving them the ability to understand why your car won’t start without having to take it apart. The term comes from control theory, an engineering concept that refers to the ability to assess internal problems from the outside.

When a system is observable, a user can identify the root cause of a performance problem by looking at the data it produces without additional testing or coding. Observability is the ability to understand a complex system’s internal state based on external outputs. To better understand the difference between observability and monitoring, let’s look at how each works and the roles they play today within software development.

Monitoring tells you when something is wrong, while observability can tell you what’s happening, why it’s happening and how to fix it. Monitoring and observability are two ways to identify the underlying cause of problems. That’s where monitoring and observability come in. Teams need a way to find the root cause of problems and quickly resolve them. When something goes wrong with an application, it impacts customers and, ultimately, impacts the business. Monitoring and observability are two ways to identify the underlying cause of problems - how are they similar and different?
