6 Signs a Dedicated Log Tool Fits Better Than a Full Observability Platform

Most growing teams eventually consolidate onto a full observability platform, and for teams correlating logs, metrics, and traces across a complex system, that’s often the right call. But a dedicated log tool still wins for a specific set of teams: ones that need to move fast, keep costs simple, and get real answers from logs without carrying the weight of a platform they don’t fully need yet. Here’s when that’s you.

Azure integration now supports service principal authentication

We’ve released some improvements to our Azure status integration. StatusGator can now read your Azure Resource Health events via a service principal. Previously the only supported authentication mechanism was OAuth. Both pull the same data and produce the same alerts – the difference is who the connection belongs to, and what happens to it over time.

Cribl On Your Coffee Break Episode 2 - Setting up Syslog

In our second video Leon picks on Syslog (because honestly, it deserves it). Cribl is the perfect tool to whip that disorganized, loud, unruly mess of a data stream into shape. By the time the month is over, you will have a pretty good idea of what Cribl can do, and how to do it. You’ll also have consumed more caffeinated beverages than is strictly appropriate...

Application Metrics caught my broken size estimator

There’s a very specific kind of frustration that comes from waiting several minutes for a video to encode, dragging it into a message, and getting hit with a “file too large” error. Then you’re blindly trying to shave off a few more megabytes by re-encoding, maybe at a lower resolution or a smaller bitrate, hoping you won’t have to do it more than one or two more times. Here’s how I used Sentry’s Application Metrics to make a more accurate video size estimator.

Visualize how CUPED adjusts experiment results with Datadog

CUPED (Controlled-experiment Using Pre-Experiment Data) is a powerful tool that can reduce metric variance and help teams obtain precise experiment results with less data. However, the difference between an experiment’s CUPED-adjusted lift and raw lift can be difficult to explain, especially when an experiment uses many pre-exposure metrics and subject properties. The CUPED adjustments visualization in Datadog Experiments breaks the difference into a sequence of specific adjustments.

From traces to experiments: A loop for improving AI agents

Let’s say your team shipped a support agent last quarter. The launch demo went well, stakeholders were pleased, and everyone moved on. A few months later, things start to look off. Summaries of long conversations are truncated, and monitors show latency spikes on tool calls to the billing API. Your team’s first instinct is to ship fixes such as tweaking prompts or upgrading the model.

Bringing the Most Advanced Sampling to the OpenTelemetry Collector

Sampling is a core skill that everyone who runs an observability pipeline at scale will learn. There are lots of tradeoffs within the various decisions you'll make from reducing bandwidth, CPU, and memory, to reducing costs and making the observability backend's performance better for users. Historically, there have only been three mechanisms, each with their own tradeoffs: However, there is a secret fourth option: adaptive tail sampling—which changes those tradeoffs.

We Let AI Agents Rewrite a 92M-Message-a-Day Service in Go. Zero Incidents.

Our Results Daemon processes about 92 million messages a day. We recently rewrote it from Node.js to Go, and we let Claude Code write it. We wanted to know whether we could trust an agentic rewrite for a critical, high-throughput production service rather than a prototype. It shipped with zero incidents, a 70% reduction in running pods, and a lighter database load.

Best Storage Monitoring Software: 10 Tools Compared

Storage rarely fails loudly. A pool fills. Latency climbs on one LUN. The first to notice is a user whose application timed out. The best storage monitoring software catches it earlier. It watches capacity, IOPS, latency and drive health across your arrays, which is what storage resource monitoring is for. In this blog, you will see: By the end you will know which one fits. Storage monitoring software tracks the health, capacity and performance of your IT storage.
