PHP Performance Monitoring

Best PHP Monitoring Tools on the Market

As of April 2022, more than 75% of websites on the internet are built using PHP (source). In other words, three out of four websites are developed using PHP! This is a significant statistic.

Given the extensive usage of PHP web applications, it is crucial to have systems in place that can automatically monitor their performance and response to the vast number of global users. As a PHP developer, it’s essential to have practical tools in your toolkit that can keep you updated on your application’s performance and promptly alert you about any potential issues.

In this article, we will discuss PHP application monitoring, highlighting the key performance metrics to consider and showcasing the top tools available in the market that can help you achieve your monitoring goals.

PHP Monitoring Metrics

‘Performance’ in the context of software development is a broad term that encompasses various aspects of an application’s behavior on the internet. To evaluate how well our application is functioning, we need to analyze its performance using different metrics.

The most valuable metrics to consider will vary depending on your specific application and organizational requirements. It’s important to understand the key performance indicators relevant to your use case.

Before diving into the list of top PHP monitoring tools, let’s explore the commonly important metrics that provide insights into your application’s performance.

Availability ↑

Availability refers to the measure of an application’s services’ availability and operability. It represents the percentage of time an application and its services are available and functioning correctly. Calculating availability typically involves tracking uptime, downtime, responsiveness, and the percentage of completed transactions.

Response Time ↓

Response time is the duration it takes for the server to respond to a client’s request. There are two primary statistics related to response time:

  • Mean response time: The average response time for each request, with shorter times being better.
  • 95th percentile response time: The time it took for 95% of transactions to complete. The closer this value is to the mean response time, the better.

Error Rate ↓

Error rate measures the number of errors encountered in your application over a specific time period. This metric includes all errors across all instances of your application running on the web.

Memory and CPU Usage ↓

Memory consumption and CPU usage are essential metrics for measuring hardware resource utilization. Monitoring platforms typically track these metrics, averaged across all running nodes. Lower values indicate more efficient resource utilization. Abnormally high values may indicate bottlenecks, while unexpectedly low values might suggest overprovisioned compute resources.

Customer Satisfaction ↑

Apart from indirect measures of user experience, specific metrics directly account for customer satisfaction. The ApDex score, a famous customer satisfaction metric provided by monitoring tools, compares the number of requests completed within a threshold time to those taking significantly longer. This score depends on the application’s response time.

For more information on the ApDex score and its monitoring, refer to the ProgramMatek website.

Top PHP Monitoring Tools

Now that we have covered the essential metrics for monitoring PHP applications, let’s explore the top PHP monitoring tools that can help you effectively track these metrics.

Scout APM

Scout APM is an Application Performance Monitoring (APM) tool that offers real-time alerts and insights about your application’s performance. In addition to capturing the mentioned metrics, Scout provides support for key performance indicators (KPIs) such as deployment tracking, error monitoring, custom contexts, and detailed tracing.
