Mastering The Faster Web with PHP, MySQL, and JavaScript

Continuous Profiling and Monitoring

In this chapter, we will learn how to install and configure profiling and monitoring tools that will help you easily optimize PHP code in a continuous integration (CI) and a continuous deployment (CD) environment.

We will start by installing and configuring a basic Blackfire.io setup in order to easily and automatically profile code when committing it to a repository. We will also learn how to install a TICK Stack in order to continuously monitor our code's performance after its deployment on a live production server.

Thus, in this chapter, we will cover the following points:

  • Installing and configuring the Blackfire.io agent, client and PHP extension
  • Integrating the Blackfire.io client with Google Chrome
  • Integrating the Blackfire.io client with a known CI tool like Travis
  • Installing and configuring a complete TICK Stack with Grafana
...

What is Blackfire.io?

As stated on the official Blackfire website (https://blackfire.io), Blackfire empowers all developers and IT/Ops to continuously verify and improve their app's performance, throughout its life cycle, by getting the right information at the right moment. It is, therefore, a performance management solution that allows you to automatically profile your code and set performance standards through assertions throughout your application's life cycle, especially in the development phaseBlackfire.io is a tool that makes what Fabien Potencier calls performance as a feature possible, by making performance tests a part of the development cycle from the very beginning of a project.

Installing and configuring Blackfire.io

...

Performance testing with Blackfire.io

Before we start, please note that this feature is available only to premium and enterprise users and that, therefore, it requires a paid subscription.

In order to automate performance testing, we will start by creating a very simple blackfire.yml file in our repository. This file will contain our tests. A test should be composed of a name, a regular expression and a set of assertions. It is always preferable to avoid creating volatile time tests as these make for very brittle tests that might yield very different results from one profiling session to the next. Examples of strong performance tests would be to check CPU or memory consumption, number of SQL queries or testing results by profile comparisons. In our case, we will create a very basic and volatile time test just for the sake of giving a short and simple example. Here is the content...

Monitoring performance with the TICK Stack

The TICK Stack was developed by InfluxData (InfluxDB) and is made of a series of integrated components that allow you to easily process time-series data generated by different services through time. TICK is an acronym that is composed of the first letters of each main product of the monitoring suite. T is for Telegraf, which collects the information we wish to obtain on our production server. I is for InfluxDB, which is a time-series database that contains the information collected by Telegraf or by any other application which is configured to do so. C is for Chronograf, a graph tool that allows us to easily understand the collected data. Finally, K is for Kapacitor, an alert automation tool.

Monitoring infrastructure performance is not only important to determine if applications and scripts are running as expected, but also allows for...

Summary

In this chapter, we have learned how to install and configure a basic Blackfire.io setup in order to easily and automatically profile code when committing it to a repository. We have also explored how to install a TICK Stack in order to continuously monitor our code's performance after its deployment on a live production server. Thus, we have seen how to install and configure profiling and monitoring tools that help us easily optimize PHP code in a continuous integration (CI) and a continuous deployment (CD) environment.

In the next chapter, we will explore how better understanding PHP data structures and using simplified functions can help an application's global performance along its critical execution path. We will start by analyzing a project's critical path and, then, fine-tune certain of its data structures and functions.

Description

This book will get you started with the latest benchmarking, profiling and monitoring tools for PHP, MySQL and JavaScript using Docker-based technologies. From optimizing PHP 7 code to learning asynchronous programming, from implementing Modern SQL solutions to discovering Functional JavaScript techniques, this book covers all the latest developments in Faster Web technologies. You will not only learn to determine the best optimization strategies, but also how to implement them. Along the way, you will learn how to profile your PHP scripts with Blackfire.io, monitor your Web applications, measure database performance, optimize SQL queries, explore Functional JavaScript, boost Web server performance in general and optimize applications when there is nothing left to optimize by going beyond performance. After reading this book, you will know how to boost the performance of any Web application and make it part of what has come to be known as the Faster Web.

Who is this book for?

The audience for this book would be PHP developers who have some basic knowledge of PHP programming and Web technologies. JavaScript programming knowledge is not necessary.

Excellent book by an excellent writer and Web developer. The author is, among others, the creator of Linux for PHP. Do not miss the foreword by Doug Bierer, an authority regarding security and php.

I bought this book in too much of a hurry. I have 45 years programming experience, but none of that was web site creation. I thought this book would give me an introduction to LAMP stacks, but it doesn't. It is intended for experts who are trying to get more speed out of their web sites. I regret buying this book at the moment.

Screenshot an Screenshot über mehrere Seiten. Man hat sich nicht mal die Mühe gemacht, Teile, die auch ohne Screenshot darstellbar wären irgendwie heraus zu nehmen. Liest sich sehr schlecht, teilweise sind die Screenshots verpixelt, meist hat man es auch nicht für nötig gehalten ein anderes Theme im Editor einzusetzen und stattdessen das Darktheme gescreened, also alles weiss auf sehr viel schwarz.Nimmt man die Screenshots raus - vor allem jene, die null Aussagekraft haben (es gibt da Sachen die scheinen mir so genaut worden zu sein, um die Seitenzahl zu erhöhen) bleiben vielleicht 50 Seiten übrig, von denen die Hälfte vielleicht irgendwie hilfreich ist.Selten so über ein "Fachbuch" geärgert.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
