PHP sensor releases

The PHP sensor passes the stack trace configuration from com.instana.tracing.global section in the agent configuration.yaml to the PHP Tracer.

This release installs PHP Tracer 5.8.1 by default.

This release fixes an interrupted exception that occurred during HTTPd module parsing on Windows.

PHP monitoring is now supported in non-root agent installations on Linux hosts.

Limitations

• Monitoring PHP runtimes in rootless Podman containers is not supported.

The PHP sensor now supports HTTP endpoint filtering by passing the filter rules configured in com.instana.tracing.filter section in the agent configuration to the PHP Tracer. For more information, see Filtering spans.

This release correctly adds instana.span_filter_config_file INI setting to the mainphp.ini file when the PHP sensor is updated from versions earlier than 2.2.5.

PHP sensor 2.4.0 provides the following features:

• Supports PHP 8.5 runtime.
• Installs PHP Tracer when PHP 8.5 runtime is detected.

PHP sensor 2.4.0 provides the following fixes:

• PHP sensor does not override the owner and group permissions of the main php.ini file when updating PHP Tracer INI settings.
• Instana PHP Tracing extension version is correctly updated after installation in the PHP runtime entity for Apache with mpm_prefork configuration.

This release adds support for Apache/HTTPd runtimes that uses a custom configuration file that is specified with the -f option.

This release provides the following fixes:

This release provides the followings enhancements:

• Maps the PHP services running in IIS to the IIS Runtime entity.
• Fixes the auto discovery of PHP-CGI SAPI processes in Linux.

PHP-CGI SAPI is now supported on Windows host.

This release adds support for monitoring PHP-FPM runtimes that run as systemd services hardened with the ProtectSystem directive.

PHP-FPM monitoring is now supported in non-root agent installations on Linux hosts.

Limitations

• Monitoring PHP-FPM runtimes in rootless Podman containers is not supported.
• Monitoring PHP-FPM runtimes with a TCP listen address is not supported.

This release fixes an issue where the PHP FPM sensor failed to display FPM metrics in Kubernetes environments that use the CRI-O runtime.

The sensor now includes a new PHP FPM plugin configuration that allows you to opt in or opt out of FPM worker pool monitoring for PHP-FPM.

The PHP-FPM sensor now uses the pm.status_listen endpoint to monitor FPM worker pools if the endpoint is configured. This improvement fixes an issue where FPM idle worker process gets stuck forever and fails to terminate when FPM sensor monitors worker pools with the pm FPM configuration set to ondemand.

The PHP Tracer now supports for FPM instrumentation for Podman containers.

Previously, PHP sensor was instantiated on AIX and Windows only after a successful installation of PHP Tracer. This issue is now fixed.

To fix security vulnerabilities CVE-2024-29131 and CVE-2024-29133, the org.apache.commons_commons-configuration2 library is updated to 2.10.1.

PHP profiling is now generally available when PHP profile sensor 3.0.0 is combined with PHP Tracer 4.0.0.
