How can I use APM to optimize the performance of PHP applications?

What is APM? Many people are hearing about the concept of APM for the first time. This article mainly describes how to use APM solutions to optimize PHP application performance. First, we will introduce the Application Performance Management (APM), a systematic solution that monitors enterprise systems in real time to achieve Application Performance Management and fault Management. Application Performance Management is a relatively new network management direction. it mainly refers to the monitoring and optimization of key business applications of enterprises, improving the reliability and quality of enterprise applications, and ensuring that users get good services, total Cost of Ownership (TCO) is reduced ). An enterprise's key business applications have powerful performance, can improve its competitiveness, and achieve business success. Therefore, strengthening application performance management (APM) can bring huge commercial benefits. Supported languages and environments Compatibility and installation requirements This article uses OneAPM, a leading enterprise in application performance management in China, as an example. The following table lists the supported application servers and application frameworks: 1. operating system CentOS 5.5 or above Ubuntu 11 or later RedHat Enterprise Linux (RHEL) 5 or above 2. PHP version PHP 5.2.13 and above PHP 5.3 and above PHP 5.4 and above PHP 5.5 and above PHP 5.6 and above 3. Database Mysql [mysql, pdo, mysqli] 4. WebServer Mod_php mode of Apache (thread security and non-thread security) FastCGI mode (for example, php-fpm) 5. specify unsupported frameworks Yaf 6. installable frameworks Wordpress Drupal Magento Zend CakePHP Codelgniter Symfony Laravel ThinkPHP Discuz Yii PHP-Agent can be installed on all PHP-based frameworks. 7.

Overview of Global Performance The application performance overview on the application homepage allows you to quickly perceive the application health and overall performance status and problems. With an overview as the entry point, you can easily trace performance metrics such as geographic information, key transactions, and error statistics to complete application performance management. The application performance overview page contains the following information: response time, performance index, throughput (unit: requests per minute in rpm), key transactions, error rate, recent events, and server information. Automatically analyze application topology Web transactions Slow transaction tracking 2. code-level performance diagnosis 3. Database Details Slow SQL diagnosis 4. External Services 5. backend monitoring 6. error message 7. reports Web transactions Database 8. set Server environment Custom transactions 9. key transactions 9. alarm policy Alert policies can be set for applications and key transactions respectively. The setting method is as follows: A. trigger Performance Index Set the number of minutes to the alert value Set how many minutes to send an alarm Error rate Set the average error rate to the warning value in minutes. Set the percentage of average error rate in how many minutes to send an alarm B. notification method Email, SMS, email + SMS C. Dispatch Application Set which applications adopt this policy User Set specific users to respond to this policy Alarm integration Alert description ----- modification required here Alarm records Alarm records are classified into notification, downtime, serious problems, and alarm problems. Install 1. get authorization number The server automatically generates the License Key authorization number. 2.
