The ultimate guide to the best open-source DevOps monitoring tools

Robust monitoring capabilities are critical to building a highly integrated and outcome-oriented DevOps process.

As more and more IT organizations across industries are imbibing the DevOps spirit either partially or completely, it is pivotal to understand the role of monitoring in the DevOps model and how open-source monitoring tools can bolster new capabilities in the DevOps landscape.

However, before we get to the monitoring part, let’s first refresh our understanding of what DevOps is all about.

DevOps: The Art and Science of building better software, faster

DevOps emerges from the deliberate unification of two traditionally siloed departments - one is development, and the other one is operations.

For decades, developers and operators have worked independently, though their roles would overlap sometimes. Moreover, their individual KRAs and priorities would often cause friction between these two teams.

The DevOps movement came into existence primarily to unify the efforts of development and operations teams and build a culture interwoven with the principles of increased communication, collaboration, and accountability for the complete product.

GitLab defines DevOps as “people working together to conceive, build, and deliver secure software at top speed. DevOps practices enable software development (dev) and operations (ops) teams to accelerate delivery through automation, collaboration, fast feedback, and iterative improvement.”

What is DevOps Monitoring?

As a concept, DevOps monitoring transcends every stage of application development, from planning and development to deployment and operations management.

It entails overseeing the entire software development and deployment lifecycle with an aim to identify bottlenecks or frictions at the earliest and drive decision-making to improve time to market and enhance customer service.

Google Cloud identifies DevOps monitoring as a key capability.

“Monitoring is a key capability because it gives you insight into your systems and your work. Properly implemented, monitoring also gives you rapid feedback so that you can quickly find and fix problems early in the software development lifecycle.”

How effective monitoring is imperative for DevOps success?

Monitoring constitutes the heart of an application that never fails to meet customer experience expectations.

Strategic and end-to-end monitoring ensures that the application is highly available and reliable and bugs are effectively identified and fixed. In DevOps, monitoring supports the core tenets of the methodology to produce higher-quality software at a rapid pace.

The absence of effective monitoring tools across the DevOps lifecycle has the potential to impact everything that DevOps methodologies have to offer to its user organizations.

The DevOps proponents, therefore, strongly advocate fortifying systems and teams with the best monitoring tools for DevOps. Although DevOps monitoring unlocks benefits across the entire SDL cycle, the most notable ones include the following:

5 key benefits of DevOps monitoring

• Greater visibility: DevOps monitoring provides real-time insights into the entire software delivery pipeline, enabling teams to identify issues and bottlenecks quickly.
• Accelerated issue resolution: By detecting issues early, DevOps monitoring helps teams address problems faster, reducing downtime and improving overall system reliability.
• Improved team collaboration: It fosters better collaboration between development and operations teams, breaking down silos and promoting a culture of shared responsibility.
• Continuous improvement: With data-driven insights, DevOps teams can continuously refine their processes, resulting in higher efficiency and better software quality.
• Reduced costs: By optimizing resource usage and minimizing wastage, DevOps monitoring can lead to cost savings, making it a valuable investment for organizations.

Harnessing the transformative potential of DevOps monitoring processes requires a strategic approach toward defining the metrics you want to track, as well as making a deliberate move to choosing the tools to do the job.

DevOps proponents can leverage paid tools as well as open-source monitoring solutions to accelerate time to market and customer experience. Here are some of the leading-edge open-source DevOps monitoring tools that companies across industries use to bolster their monitoring efforts.
