OFF-CPU flame diagram, is used to analyze the program is not efficient use of the CPU when, where the consumption, here (http://www.brendangregg.com/FlameGraphs/offcpuflamegraphs.html) have a detailed introduction. The data collection is more complex than the ON-CPU flame diagram and can be used in the Openresty-systemtap-toolkit (Https://github.com/

A system has recently been used with Nginx+lua+redis to support high-concurrency high-traffic applications. Development when suddenly thought Golang can also achieve the same effect. So I wrote a simple code comparison. Specifically not much to do introduction, online a lot about Nginx+lua+redis building high-concurrency application introduction. I'm using the Openresty+lua+redis. The test results are first posted, and the machine is th

: This article mainly introduces nginx + lua + redis. For more information about PHP tutorials, see. Recently, nginx + lua + redis is used as a system to support high-concurrency and high-traffic applications. During development, I suddenly thought about whether golang could achieve the same effect. So I wrote a simple code comparison. I will not introduce it more. I will introduce nginx + lua + redis to build highly concurrent applications on the Internet. I am using

relatively worst. With this simple test, you can see the high concurrency capability of Ngx_lua. Ngx_lua's developers have also done a test comparison between nginx+fpm+php and Nodejs, and the result is that Ngx_lua can reach 28000rps, while Nodejs has a bit more than 10,000, and PHP has the worst of 6000. There may be some configuration I did not match to cause Ngx_lua RPS not that high. Ngx_lua installation Ngx_lua installation can download module source code, compile Nginx, but recommend

Background:A sequence of HTML pages needs to be deployedNginx-based deployment:The Openresty-based Nginx configuration is used in this paper.Simply configure Nginx configuration files so that when you start Nginx, you can enable these configurations to allow click-to-jump access for well-written HTML pages. And this is the focus of this article.Configuration Mode 1:Nginx configuration system consists of a master configuration file and some other auxil

running, which require some common functions, such as authentication, flow control, monitoring, and log statistics.In traditional monomer applications, these functions are generally embedded in the application and run as a component. However, in microservices mode, there are dozens of or even hundreds of different types of applications that can run independently, and continuing to use this approach can result in very high management and publishing costs. Therefore, it is necessary to abstract a

# About Kong# # BackgroundWhen we provide API or microservices, we usually use openresty nginx for traffic forwarding or adding some rules or functions, but as the number of services and references increase, complex network environment,Making maintenance difficult, not easy to scale, some features being duplicated in multiple services, we expect a tool to be centrally managed. !

traffic is particularly large, Nginx appeared on the short board when used, but the actual situation, generally rarely exhaust nginx performance, even if there, can also be achieved through the ngxin level expansion,So it's still using Nginx as load balancer. Here is the key point for this project: 1. Registration and health testing of services there is no technical difficulty, there is no explanation here. 2. On the operation of Nginx up and down line, here is a difficult point, because Nginx

At first, I was just looking for an API gateway to prevent the API from being maliciously requested, finding a lap to discover the Nginx-based openresty(Lua language) expansion module Orange is good (also found in Kong , but the feeling of complexity is useless), but also lazy to use Vagrant combined with Docker to quickly set up the environment, based on the dockerfile of others to run through the whole experiment, feel good.
