In leaf-spine data center networks, traffic often becomes imbalanced, leaving some uplinks idle and resulting in wasted bandwidth. Kentik helps engineers identify underutilized paths, diagnose the causes, and take corrective action using enriched telemetry, visual topology maps, and intelligent alerts, turning hidden inefficiencies into actionable insights.

Most of the time, nothing’s broken. Traffic’s flowing, alerts are quiet, and everything seems fine. That’s peacetime, when no one’s getting paged. Coroot helps in both peacetime and wartime. When things go wrong, it guides you to the root cause fast. But during peacetime, it helps you spot risks early, clean up inefficiencies, and prevent those incidents from happening in the first place.

Your app logs start simple—maybe a few print() or logging.info() calls. But in production, things get noisy. Thousands of log lines per minute, scattered across services, and it’s hard to know what matters. This is when tools like Graylog and the ELK stack help. They let you collect, search, and make sense of logs, but they do it in different ways. This guide breaks down how each one handles setup, scale, and day-to-day use.

It’s late, you get an alert, and Grafana is down. The reason? It ran out of memory. If you’ve ever watched Grafana slowly eat up RAM until it just stops responding, you know how frustrating that can be. Memory can spike quickly, especially with complex dashboards and multiple data sources. This guide will help you understand what’s going on and how to keep Grafana running without surprises.

If you’re a Splunk user relying on Dynamic Data Self Storage (DDSS) or Active Archive (DDAA), you’re likely familiar with this frustrating loop.

The past few months, we’ve working on improving our uptime check. We proud to announce that this improved check is now available for all users. You don’t have to do anything to get it (unless you are not subscribed to Oh Dear, in that case your should subscribe to Oh Dear ), all our users now have it enabled by default. In this blogpost, I’d like to give an overview of the changes and some background why we changed some things.

Synthetic monitoring is a vital practice to proactively track the health and performance of web applications. Instead of waiting for users to report problems, synthetic monitoring helps developers catch issues before they impact real users. One powerful type of synthetic monitoring is the browser check. These checks go beyond basic ping checks, simulating how a user would actually interact with your website’s interface.

In March, we announced that Grafana OnCall (OSS) had entered maintenance mode. However, OnCall’s development continues in Grafana Cloud as Grafana Cloud IRM, combining on-call management and incident response into one integrated solution. Many users told us they still want to self-host Grafana and rely on Grafana Alerting to detect potential issues early—but they also need to escalate and manage incidents using an incident response management (IRM) solution.

Security Orchestration, Automation, and Response (SOAR) platforms empower security teams to streamline and accelerate their response to cyber threats. By integrating with existing security tools, automating repetitive tasks, and standardizing incident response workflows, SOAR helps organizations proactively defend against attacks while improving operational efficiency.

In a world of constant disruption, operational resilience is now mission critical. From cyberattacks and misconfigurations to vendor outages and natural disasters, today’s enterprises are navigating risks that move faster and hit harder than ever before. As we enter 2025, operational resilience has evolved from a best practice to a board-level imperative.
