   Web Application Monitoring: Overview
   

   Web application monitoring is akin to the dashboard of a car. Just as a car dashboard provides various metrics—battery output, speed, engine revolutions per minute (RPM), odometer readings, oil temperature, and fuel level—web application monitoring tools collect and display metrics that indicate the health of your web application.

   What Is Web Application Monitoring?
   

   Web application monitoring involves identifying critical metrics that reflect the application’s health, collecting this data using monitoring tools like Prometheus, and visualizing it through dashboards in tools like Grafana.

   For example, in web application monitoring:

   • Counters: These are similar to an odometer, always increasing over time. Common counters include the number of requests served, completed batches, errors, and CPU time used by a process.
   • Gauges: These metrics fluctuate, similar to the engine RPM. They can include CPU usage, memory usage, disk space, and the number of active connections.
     

     Why Does PHP Web App Monitoring Matter?
     

     Effective monitoring is crucial for maintaining the performance and security of PHP web applications. Performance issues can lead to significant financial losses, especially during critical sales periods like Black Friday. Monitoring ensures you can identify and address issues promptly, ensuring a seamless user experience.

     Benefits of Web Application Monitoring
     

     Comprehensive monitoring offers real-time data, enabling quick responses to issues and better service to your users. For example, monitoring metrics like requests per minute and error rates can help you gauge the performance of your web application during high-traffic periods.

     Considerations for Web Application Performance Monitoring
     

     Determine Your Web Application Performance Metrics
     

     Before going live, it’s beneficial to perform synthetic testing to determine the key performance metrics. Tools like JMeter and BlazeMeter can help push your application to its limits in lower environments to identify potential performance issues.

     Evaluate Web Application Performance Monitoring Tools
     

     Choosing the right tools for monitoring is vital. Different enterprises might use various tools, and it’s essential to have a cohesive platform that supports collaboration between developers and operators.

     Improve Performance With Zend PHP App Monitoring Tools
     

     Zend offers a range of tools and services for PHP app monitoring. Whether you prefer a hands-on approach or want to outsource monitoring, Zend provides solutions that cater to different needs.

     How to Use ZendPHP With Grafana for Web Application Monitoring
     

     Step One: Install Your Exporters
     

     Start by installing exporters that scrape metrics from your web application components:

7. Host Machine: Use the node_exporter.
8. PHP-FPM: Use the php-fpm_exporter.
9. Web Server: Use the apache_exporter for HTTPD or nginx-prometheus-exporter for nginx.
   

   Step Two: Securely Expose Your Exporters
   

   Configure these exporters to accept connections on unique ports bound to localhost and expose them through a reverse SSL proxy requiring basic authentication.

   Step Three: Add Endpoints to Prometheus TSDB Scraper
   

   Add the endpoints to the Prometheus TSDB configuration, ensuring secure connections and appropriate authentication.

   Step Four: Connect Grafana to Prometheus
   

   After installing and configuring Grafana, add your Prometheus server as a data source.

   Step Five: Import Default Dashboards for Your Exporters
   

   Import default dashboards for each exporter to visualize your data in Grafana.

   Final Step: Customize Your Dashboards
   

   Tailor the default dashboards to meet the specific needs of your application for enhanced visibility into performance and uptime.
