Top observability tools for 2022

Observability tools can give developers and IT administrators better insight on applications to improve delivery, performance and customer experience -- and avoid potential issues.

Many development teams have adopted a microservices architecture that enables them to deploy their applications across distributed environments. Although this makes the applications easier to build, deliver and scale, it can also make it more difficult to track and troubleshoot the components that make up the environment. Yet organizations need visibility into these components to understand how their applications are behaving. For this reason, many have turned to observability tools, which enable them to monitor their distributed systems and respond quickly to any problems with the application delivery.

What are observability tools?

An observability tool provides a centralized platform for aggregating and visualizing telemetric data that has been collected from application and infrastructure components in a distributed environment. The tool monitors and analyzes application behavior and the various types of infrastructure that support application delivery, making it possible to proactively address issues before they become serious concerns.

An effective observability platform is more than just a monitoring tool. It builds on traditional monitoring capabilities, but provides deeper insights into the data that can help to optimize performance, ensure availability and improve the customer experience. To achieve this, most observability tools collect and aggregate three types of telemetry data:

  • Metrics. Measurements of how a service or component performs over time. For example, an observability tool might gather metrics about memory usage, bandwidth utilization, HTTP requests per second or an assortment of other systems.
  • Logs. Records of events that occur on a specific system or application. The event information might be recorded as plain text, as structured data or in a binary format. Event logs are often the first thing administrators and developers look at when troubleshooting system or application issues.
  • Traces. Representational profiles of entire processes as they're carried out across a distributed system. A trace links together the events in a single request or transaction to provide a complete picture of how it flows from one point to the next. For example, traces can show how applications are contending for network and storage resources.

These three types of telemetry data are often referred to as the pillars of observability because of the important roles they play. Metrics, logs and traces provide organizations with the data they need to understand when and why a distributed application is behaving the way it is. With the right observability platform, organizations have visibility into all layers of the application stack, enabling them to gain comprehensive insights into their distributed systems over the long term.

How to choose the best observability tool for your business

Selecting an observability tool is no small task. Decision-makers must choose from a growing number of platforms whose differences aren't always apparent. At the same time, they must determine which tools best meet their specific needs -- both now and in the foreseeable future -- and are flexible enough to accommodate changing business requirements. When evaluating observability platforms, decision-makers should consider the following guidelines:

  • The platform should be easy to deploy and manage, automate multiple processes, and provide an interface that's intuitive and easy to navigate.
  • The vendor should provide ongoing support that includes timely updates and product improvements on a regular basis.
  • The platform's underlying infrastructure and supporting components should be reliable and provide easy scalability, without adding undue overhead to IT operations.
  • The platform should support and easily integrate with the languages, frameworks, platforms and tools that an organization is already using or plans to use to support its distributed applications.
  • The platform should provide organizations with comprehensive, real-time visibility into their monitored applications and infrastructure, while delivering the data necessary to make critical business decisions.
  • Administrators should be able to easily access telemetry data, reports, visualizations, KPIs and other information from a centralized dashboard to quickly and easily gain real-time insights into the collected data.
  • The platform should have the ability to generate alerts and notifications that ensure critical information gets to the right people as quickly as possible.
  • The platform should incorporate AI, machine learning, advanced analytics or other advanced technologies to help better use the collected telemetry data.
  • The platform should offer predictable and competitive pricing that enables customers to operate within budget.

Ultimately, an observability tool must be able to help organizations optimize application delivery, improve the customer experience and meet their business goals. To this end, decision-makers should evaluate prospective platforms based on the tools, processes and infrastructure they use to support their distributed applications, looking for platforms that help them gather and understand their telemetry data. Only then will they be able to implement an observability strategy that can help them meet the challenges that come with modern applications.
