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.

Your team is responsible for ensuring the reliability and performance of your organization’s critical applications and infrastructure. What keeps you up at night? Your applications are more complex, distributed and cloud-native than ever, meaning that understanding what’s happening under the hood has never been more complex than it is now. Is it system bugs, or data bottlenecks? Chasing alerts for latency or service degradation that may or may not be business-critical?

Observability is a buzzword that has gained a lot of traction in the IT industry lately. But what does it really mean, and how does it relate to the challenges that modern IT organizations face? At SolarWinds, we believe that the current analyst definitions of observability are too narrow and APM-focused. They focus too much on the cloud, neglecting critical on-premises assets and restricting where customers can deploy their observability solutions.

Datadog and Splunk are leading monitoring and observability platforms that offer comprehensive solutions for modern IT environments. Both tools share a wide range of features, making it challenging to choose between them. This article compares Datadog and Splunk on crucial aspects like application performance monitoring (APM), log management, search capabilities, and more to help determine which platform best fits your organization.
