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.

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.

Modern Applications can use a lot of external services, some of those interactions are expected, others not so much. There could be many reasons for those unexpected interactions, ranging from security vulnerabilities and various malware to outdated code and various reporting and statistics software may report to its creator or a third party. These unexpected interactions can be a security risk, and may also raise privacy concerns.

Every Python developer has heard about the GIL (Global Interpreter Lock) This lock simplifies memory management and ensures thread safety, but it also limits the performance of multi-threaded, CPU-bound programs because threads can’t run Python code in parallel. Here is a great explanation of why Python requires the GIL by Python’s creator, Guido van Rossum: Guido van Rossum: Will Python ever remove the GIL? | Lex Fridman Podcast Clips.

If you look at typical Application interaction with service point it tends to happen in two stages – first we connect to the Service and when we are interfacing through that established connection. In this description though one thing stays invisible – you can’t simply connect to the Service through the hostname – that host name needs to be resolved into an IP address, and if this name resolution process does not work or does not perform, the application suffers.

Metrics, logs, traces, continuous profiling, and SLO-based alerting, supercharged with predefined dashboards and inspections.
An open-source observability platform built for simplicity. Say goodbye to manual analysis of metrics, logs, and traces. Gain actionable insights and focus on remediation.
Observability made simple:
- Zero-instrumentation: Coroot uses eBPF to automatically collect comprehensive telemetry data, including metrics, logs, and traces. It provides a detailed Service Map of the entire system, eliminating blind spots. Coroot also includes predefined inspections that can identify root causes for over 80% of issues without requiring any configuration.
- Application Health Summary: Coroot’s Application Health Summary feature makes it easy to understand the status of your services, even when you have hundreds of them. It provides instant insights into application logs and tracks Service Level Objectives (SLOs) for efficient performance monitoring.
- Distributed Tracing: Coroot’s distributed tracing helps you answer critical questions about your system’s performance. Coroot fully supports OpenTelemetry, ensuring no vendor lock-in. Struggling to instrument legacy or third-party services? Coroot’s eBPF-based instrumentation captures requests without any code changes.
- Log Monitoring: Grasp insights from logs with just a quick glance. Coroot performs low-overhead log analysis right on the node to identify message severities and recurring patterns. This process is seamless and compatible with a wide range of log formats, providing valuable meta-information for quick and easy log analysis.
- Continuous Profiling: Coroot’s Continuous Profiling allows you easily identify and analyze any unexpected spikes in CPU and memory usage down to the precise line of code. This allows you to quickly pinpoint and resolve performance bottlenecks, optimize your application’s resource utilization, and deliver a faster and more reliable user experience.
- Deployment Tracking: Coroot discovers and monitors every application rollout in your Kubernetes cluster. Each release is automatically compared with the previous one, so you’ll never miss even the slightest performance degradation. No integration with your CI/CD pipeline is required.
- Cost Monitoring: Every developer understands that in order to optimize something, you must first measure it. The same principle applies to you cloud costs – measuring them is crucial for optimization. Now you can easily monitor you cloud costs with Coroot. It doesn’t require access to you cloud account or any other configurations.
