Late last year, Datadog announced something called Flex Logs, a “more affordable” warm storage tier for log data. Designed for high-volume datasets that are infrequently queried and don't require real-time analysis, the Flex Tier offers Datadog Log Management customers a third option for data storage.

According to the 2024 State of Production Readiness report, 54% of engineering leaders said poor production readiness standards contributed to a decrease in developer productivity. But how? If software falls out of alignment with best practice—including those designed to maintain the health, observability, and security of software—developers wind up spending more time finding information and fixing issues than building new value.

Guide for kubectl logs with a cheat sheet. Learn to efficiently debug and monitor Kubernetes pods, from basic commands to advanced techniques.

Many organizations use Oracle databases for their ability to be deployed anywhere, embedded security features, robust data analysis capabilities, and scalability. But manually managing Oracle databases can be impractical, requiring constant attention to optimize performance.

eBPF is a powerful technology used by many observability solutions, including Coroot. While web-based observability tools like Coroot are invaluable, there’s a specific class of eBPF tools that often go overlooked (besides Brendan Gregg of course): eBPF Linux Command Line Tools. These tools are essential for diving deep into complex performance issues. But first – why would you need those at all if you have convenient observability focused web applications?

In this blog post we will look at runqlat and runqslower commands. They are available in both BCC and bpftrace tool collections. One of the core functions of Linux operating system is to schedule processes across available CPUs. When service gets a request, Linux typically will need to schedule the process, processing that request to run on one of CPUs. This might be very quick process if idle CPU is available or it can take significant time, if all CPUs are currently busy running different processes.

In this blog post we will look at gethostlatency command. It is available in both BCC and bpftrace tool collections. Most applications and services use hostnames, rather than IP addresses to communicate with other services. This means before connection to the service can be established, another request needs to be made – to DNS (Domain Name System). As such its performance and availability impacts performance of virtually all services in your environment, yet it is often ignored.

In this blog post we will look at filetop command. It is available in BCC tool collection. Disk IO is one of the key activities happening on the system, especially for data intensive systems running databases or serving files.

If you're like me and have less than twenty years of software engineering experience, the thought of a world without Git doesn't seem possible. When I started to research for this post, I almost fell out of my chair when I read that Git was created in 2005. It doesn't seem that long ago... either that, or I'm simply getting old. When I started programming, I asked myself a question I sometimes still ask myself today - How does git work? I often find myself being scared of certain Git commands.

Kubernetes is now the industry standard for cloud-based organizations. Slowly, many enterprises and mid-level companies are adopting it as the default platform for managing their applications. But we all know Kubernetes adoption has its challenges, as well as its associated costs. How do we decide when and what to migrate to Kubernetes? Does migrating to Kubernetes mean overhauling all DevOps processes? Adopting K8S should not lead to an overhaul of your DevOps process - it should complement it.
