When Solr performance degrades, everyone notices - except maybe your monitoring system. The right metrics can alert you to problems before your users start complaining. This guide walks through the essential Solr metrics that matter for production deployments.

Choosing the right observability setup isn’t just a checkbox—it affects how quickly you can detect issues, debug them, and keep your systems reliable. CloudWatch and OpenTelemetry take different paths to that goal: one is a managed service tightly coupled with AWS, the other a flexible, open-source framework that's becoming a go-to in modern monitoring stacks.

Monitoring complex PHP applications can be challenging. When systems span multiple services and environments, traditional logging approaches often fall short. OpenTelemetry offers a solution - an open-source, vendor-neutral framework that standardizes how we collect and export telemetry data. This guide covers practical implementation steps for DevOps engineers working with PHP applications.

Message queues quietly power a lot of what happens behind the scenes in distributed systems. RabbitMQ is no exception—when it’s working, you don’t notice it. But when it’s not, things break in ways that are hard to trace. This guide walks through what you need to monitor in RabbitMQ, how to set it up, and how to troubleshoot when things go wrong—so you’re not stuck guessing when messages go missing.

When your MongoDB database slows down, it affects your entire application stack. Performance issues can range from minor inconveniences to major outages, making a solid understanding of MongoDB metrics essential for any DevOps engineer. This guide covers the key performance metrics you need to monitor in MongoDB, how to interpret what you're seeing, and practical steps to resolve common issues.

Python powers critical applications across countless organizations, from data processing pipelines to web services that handle millions of requests. While Python's readability and extensive ecosystem make it a developer favorite, its performance characteristics require thoughtful monitoring. As systems grow in complexity, understanding what's happening inside your Python applications becomes increasingly important.

Kubernetes production environments require robust alerting to catch problems before they impact users. While monitoring shows system state, proper alerting tells you when something needs attention. This guide outlines 15 key Kubernetes alerts that help DevOps teams avoid outages and minimize downtime. For each alert, we provide implementation guidance and troubleshooting steps to resolve common issues quickly.

Docker containers isolate application environments, making performance monitoring essential for visibility and stability — especially at scale. To manage production effectively, teams need clear insights into resource usage, bottlenecks, and failure points. This guide covers key Docker metrics, how to collect them, and how to use that data to keep your containerized systems running smoothly.

In modern distributed architectures, observability has shifted from optional to necessary. OpenTelemetry has emerged as the standard framework for telemetry data collection, with exporters serving as the critical bridge to your backend monitoring systems. For developers at any stage—those new to observability practices or those refining existing monitoring setups—a solid grasp of OpenTelemetry exporters will significantly reduce debugging time and improve system visibility.

For DevOps teams managing mission-critical databases, SQL Server observability is a fundamental capability that provides comprehensive insight into database performance and health. Effective observability practices enable teams to identify potential issues before they impact end users and provide the context necessary to resolve problems efficiently. SQL Server observability involves collecting and analyzing metrics, logs, and traces to build a complete picture of database behavior.
