In December 2022, the latest version of HAProxy, 2.7.0, was released. This open-source software is both a proxy and a load balancer, and is immensely popular due to the sheer volume of features it provides to help reduce or even avoid downtime and manage web traffic. Website or application downtime is disastrous for businesses. You want to serve as many users as possible, but if you have nothing in place to manage traffic, then your web applications can quickly become overwhelmed and fail.

Flaky tests are a problem that are found in almost every codebase. By definition, a flaky test is a test that both succeeds and fails without any changes to the code. For example, a flaky test may pass when someone runs it locally, but then fails on continuous integration (CI). Another example is that a flaky test may pass on CI, but when someone pushes a commit that hasn’t touched anything related to the flaky test, the test then fails.

I’ve always been wary about vendor events. In my experience, many of them are mostly marketing pitches, with little or no content that is applicable to my use cases. Despite that, last year I decided to convince my manager to let me attend ObservabilityCON 2022 to see what I could learn from it. My hope was that I would be able to get practical knowledge that could be applied as soon as I got back to work. (Spoiler alert: I did!)

For the sake of security, performance and uptime, IT pros must find problems on the network immediately and fix them fast. Hmm. Sound like network detection and response (NDR)? It is.

Jaeger’s HotROD demo has been around for a few years. It was written with OpenTracing-based instrumentation, including a couple of OSS libraries for HTTP and gRPC middleware, and used Jaeger’s native SDK for Go, jaeger-client-go. The latter was deprecated in 2022, so we had a choice to either convert all of the HotROD app’s instrumentation to OpenTelemetry, or try the OpenTracing-bridge, which is a required part of every OpenTelemetry API / SDK.

You don’t often see real change, but when you do see it you know it. Artificial Intelligence/Machine Learning toolsets like ChatGPT are finally starting to offer broad capabilities that will benefit a mass audience. These tools are moving out of the domain of data scientists and math nerds and into mass markets with a little bit for everyone. The potential reach is awesome and a little scary.

Traffic telemetry is the data collected from network devices and used for analysis. With traffic telemetry, engineers can gain real-time visibility into traffic patterns, correlate events, and make predictions of future traffic patterns. As a critical input to a network observability platform, this data can help monitor and optimize network performance, troubleshoot issues, and detect security threats. However, traffic telemetry can be difficult to understand.

If you’re an Icinga user, you already know the importance of having a streamlined and efficient configuration management process. With the release of Icinga Director Branches v1.3, this process just got even better! In this latest version, Icinga Director introduces several enhancements to its branching system, making it even easier to manage and deploy your Icinga 2 configurations.

When it comes to your SQL Server, performance degradation is a costly, time-consuming issue. There may be any number of reasons why your SQL Server performance may be diminishing, but one of the biggest culprits tends to be memory usage.

Docker logs play a critical role in the management and maintenance of containerized applications. They provide valuable information about the performance and behavior of containers, allowing developers and administrators to troubleshoot issues, monitor resource usage, and optimize application performance. By capturing and analyzing log data, organizations can improve the reliability, security, and efficiency of their containerized environments.
