Overview

PHP-FPM (FastCGI Process Manager) is a web tool used to speed up the performance of a website. It is much faster than traditional CGI based methods and has the ability to handle tremendous loads simultaneously.

Use the PHP-FPM integration to:

Collect metrics related to the pool and process.
Create visualizations to monitor, measure, and analyze usage trends and key data, deriving business insights.
Create alerts to reduce the MTTD and MTTR by referencing relevant logs when troubleshooting an issue.

Data streams

The PHP-FPM integration collects metrics data.

Metrics provide insight into the statistics of the PHP-FPM. The Metrics data streams collected by the PHP-FPM integration include pool and process so that the user can monitor and troubleshoot the performance of the PHP-FPM instances.

Data streams:

pool: Collects information related to the connection handling, queue metrics, process manager configuration, process activity and performance indicators.
process: Collects information related to the request metrics, the latest CPU and memory usage and the current running state.

Note:

Users can monitor and view the metrics inside the ingested documents for PHP-FPM in the logs-* index pattern in Discover.

Compatibility

This integration has been tested against v8.2 and v8.1 standalone versions of PHP-FPM.

Requirements

You need Elasticsearch for storing and searching your data and Kibana for visualizing and managing it. You can use our hosted Elasticsearch Service on Elastic Cloud, which is recommended, or self-manage the Elastic Stack on your own hardware.

In order to ingest data from PHP-FPM, you must know the host(s) and status path of the PHP-FPM instance.

Host configuration format: http[s]://host[:port]

Example host configuration: http://localhost:8080

Status path configuration format: /path

Example Status path configuration: /status

Setup

For step-by-step instructions on how to set up an integration, see the Getting Started guide.

Validation

After successfully configuring the integration, click on the Assets tab of the PHP-FPM integration to display the available dashboards. Select the dashboard for your configured data stream, which should be populated with the required data.

Troubleshooting

If host.ip appears conflicted under the logs-* data view, this issue can be resolved by reindexing the indices of the Pool and Process data streams.

Metrics reference

Pool

The pool data stream collects metrics related to the setup and contents of the FPM status page.

An example event for pool looks as following:
