eBPF Linux Command Line Tools

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?

runqlat and runqslower - eBPF command line tools

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.

gethostlatency - eBPF Command Line Tools

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.

The four pillars of observability

When discussing the technical foundations of observability, several key components, often referred to as the “pillars,” emerge. While there is no universally agreed-upon number of pillars, this post will focus on four fundamental elements: metrics, logs, traces, and profiles. Due to the vast amount of data generated by metrics, logs, and traces, sampling is often employed to reduce data volume while maintaining representative information.

Hidden gems of observability!

Observability isn't just a buzzword—it's a vital component of modern computing. In recent webinar Peter Zaitsev discusses the multifaceted world of observability, highlighting its critical role in ensuring both application performance and user experience. Discover how different systems, from application performance management (APM) to infrastructure monitoring, collaboratively work to provide insights into user interactions and business outcomes. Explore why understanding these dynamics is essential for both developers and businesses striving for excellence.

Are Cloud Observability Solutions Breaking the Bank? #youtubeshorts #observability #devopstools

Is the price of cloud observability becoming a burden for your infrastructure? Many professionals are concerned about the skyrocketing costs associated with proprietary observability tools like Datadog. With major acquisitions, such as Cisco's purchase of Splunk, one has to wonder if affordability is compromised in favor of profit. How essential is observability in today's tech landscape, and what alternatives exist?

Is too much data making your job harder? #youtubeshorts #dataanalytics #observability

What happens when capturing vast amounts of data becomes overwhelming instead of insightful? For years, vendors have prioritized collecting vast metrics, boasting thousands of data points. But is this approach beneficial, especially for developers who may not be observability experts? Understanding metrics shouldn't feel like deciphering a foreign language. Coroot is an open source observability platform that helps engineers fix service outages and even prevent them. It continuously audits telemetry data to highlight issues and weak spots in your services.
