Linux debugging tools that developers and operators must look at [Recommended]

System performance expert Brendan D. Gregg updated his famous talk (Linux Performance Tools) and slides on Linux performance at the LinuxCon NA 2014 conference. The tools used in daily Linux development are summarized from the perspectives of monitoring, testing, optimization, and configuration. Below are the main pictures and information, I hope it will be helpful to you.

Performance Tools (Linux Performance Tools-full)

This picture is a high-resolution version of the monitoring, testing, and tuning process. They will be displayed separately according to different categories later.

Linux Performance Benchmark Tools

Benchmark is an evaluation method, which consists of three parts: data set, workload, and measurement indicators. It has long-term applications in the entire computer field.

The most successful application of Benchmark in the computer field is performance testing, which mainly tests the execution time, transmission speed, throughput, resource utilization, etc. of the load.

Linux Performance Observability Tools

According to the different monitoring contents, the tools can be divided into three levels: basic, intermediate and advanced. Corresponding to the following three chapters respectively

Basic Linux Monitoring Tools

perf-tools

perf-tools: is a toolset created by Brendan Gregg. Its goal is to achieve maximum functionality with minimal dependencies and to be easy to install and use.

Do one thing and do it well. ——Brendan Greg

sar

sar (System Activity Reporter) is one of the most comprehensive system performance analysis tools on Linux. It can report system activities from many aspects, including: file reading and writing, system call usage, disk I/O, CPU efficiency, memory usage, process activity and IPC-related activities.

Linux Performance Tuning Tools

Most systems will respond to increased load with some degree of performance degradation. The ability of a system to accept a higher load is called scalability, and modifying the system to handle the higher load is the purpose of Performance Tuning Tools.

Tracing Tools (Linux bcc/BPF Tools)

A new technology is emerging in Linux that provides system administrators and developers with a host of new tools and dashboards for performance analysis and troubleshooting. It is called BPF (Berkeley Packet Filter).

eBPF is an enhanced version of BPF and has been added to the Linux 4.x series kernel. Can do more than just filter packets, allowing custom analyzers to be executed on Linux dynamic traces, static traces, and analysis events.

Static Information (Linux Static Performance Tools)

I believe these are very familiar to Linux practitioners.

If you want to do your work well, you must first sharpen your tools. Good tools can quickly locate problems and shorten the debugging cycle. There are so many tools on the Linux platform that it's hard to tell which are the best. The most tried and tested simple tools are all in the above article. Do you know them all?

Summarize

The above is the Linux debugging tools that I introduced to you, which are indispensable for development and operation and maintenance. I hope it will be helpful to you.
