PHP FPM 🔗
The Splunk Distribution of OpenTelemetry Collector uses the Smart Agent receiver with the
collectd/php-fpm
monitor type to monitor PHP-FastCGI Process Manager
(FPM) using the pool status URL.
This integration is only available on Kubernetes and Linux.
Benefits 🔗
After you configure the integration, you can access these features:
View metrics. You can create your own custom dashboards, and most monitors provide built-in dashboards as well. For information about dashboards, see View dashboards in Splunk Observability Cloud.
View a data-driven visualization of the physical servers, virtual machines, AWS instances, and other resources in your environment that are visible to Infrastructure Monitoring. For information about navigators, see Use navigators in Splunk Infrastructure Monitoring.
Access the Metric Finder and search for metrics sent by the monitor. For information, see Search the Metric Finder and Metadata catalog.
Installation 🔗
Follow these steps to deploy this integration:
Deploy the Splunk Distribution of OpenTelemetry Collector to your host or container platform:
Configure the monitor, as described in the Configuration section.
Restart the Splunk Distribution of OpenTelemetry Collector.
Install PHP 🔗
To configure the PHP-FPM service itself to expose status metrics, follow these steps:
Activate the status path. See the PHP documentation for more information.
Configure access through the web server. The following example shows how to configure access for NGINX:
location ~ ^/(status|ping)$ { access_log off; fastcgi_pass unix:/run/php/php-fpm.sock; include fastcgi_params; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; }
Restart both the web server and PHP-FPM.
Make sure that the URL you provide to reach the FPM status page through
your web server ends in ?json
. This returns the metrics as json
,
which this plugin requires.
Configuration 🔗
To use this integration of a Smart Agent monitor with the Collector:
Include the Smart Agent receiver in your configuration file.
Add the monitor type to the Collector configuration, both in the receiver and pipelines sections.
