New Features

  • Support for Distributed tracing

    Distributed tracing lets you see the path that a request takes as it travels through your distributed system. By showing the distributed activity through a unified view, you can troubleshoot and understand a complex system better than ever before.

    Distributed tracing is available with an APM Pro or equivalent subscription. To see a complete distributed trace, you need to enable the feature on a set of neighboring services. Enabling distributed tracing changes the behavior of some New Relic features, so carefully consult the transition guide before you enable this feature.

    To enable distributed tracing, two parameters should be changed in the newrelic.ini file:
    newrelic.distributed_tracing_enabled = true
    and
    newrelic.transaction_tracer.threshold = 0

    Read more about about distributed tracing in the PHP Agent.

Bug Fixes

  • A bug in the PHP agent resulted in databaseCallCount attributes no longer being attached to Transaction events. The 8.4 release restores these attributes.
  • Predis 2 cluster connections could not be instrumented due to internal changes in Predis. The 8.4 release fixes this.

Bug Fixes

  • In rare cases, during a reset of the apache web server, the agent and mod_php would hang with 100% CPU utilization. This has been fixed.

Bug Fixes

  • Fixed an entire category of bugs where a Drupal hook whose hook name matched its module name resulted in the generation of empty metric names.

Operating Systems Support

  • This release of the PHP Agent removes support for the Solaris operating system. For Solaris support, please install agent version 8.1 or prior.

Upgrade Notices

  • The PHP Agent API call newrelic_set_appname has been updated with security improvements in anticipation of future releases.

Upgrade Notices

  • The newrelic.daemon.ssl ini setting has been removed to increase security. Transport Layer Security (TLS) will now always be used in communication with the New Relic collector.
  • Laravel Queue support has now been enabled for all users. If newrelic.feature_flag=laravel_queue is set, it will now be ignored.

Bug Fixes

  • On FreeBSD and Solaris, when newrelic.daemon.port is configured to use TCP to connect the agent to the daemon, the agent would have difficulty receiving application configuration data from the daemon due to the default timeout of 100 milliseconds matching the delay enforced by the FreeBSD kernel as part of its implementation of Nagle's algorithm. The PHP agent will now set the TCP_NODELAY flag when connecting to the daemon via TCP, which increases the reliability of the agent:daemon connection.

New Features

  • Support for PHP 7.2 has been added.

Bug Fixes

  • Datastore metrics would not be generated for Predis users who stopped and started the transaction after instantiating a Predis\Client object. This included users using the newrelic_set_appname() API. This has been fixed.

New Features

  • Internal functions can now be instrumented by enabling the newrelic.transaction_tracer.internal_functions_enabled configuration setting. When enabled, internal functions will appear in transaction traces like PHP functions.

    Note that enabling this option may result in transactions being slower, especially when collecting many traces from PHP 5.x. Enabling this option is only recommended when specifically debugging performance issues where an internal function is suspected to be slow.

Bug Fixes

  • In some cases, Magento 2's UI Component JSON data sources return with an (incorrect) Content-Type of text/html. This resulted in auto instrumentation insertions into JSON data that contained a <head> string. We now identify these specific JSON data sources and ensure the auto instrumentation is not inserted into this JSON data.

  • On PHP 7, using file_get_contents() to get a HTTP URL in a function which also read from $http_response_header resulted in the external call not being linked correctly in the APM UI: the external call would appear in transaction traces without a link to the receiving application. This has been fixed.

  • Using curl_setopt_array() to set options on a cURL handle could result in cross application tracing failing. This has been fixed.

  • When generating explain plans for queries issued with MySQLi, the PHP agent could bind parameters from the wrong query if the PHP object ID had been reused internally. This has been fixed.

  • Due to a change in Laravel 5.5's router API, the PHP agent would crash when automatically naming a Laravel transaction. This has been fixed.

  • On PHP 7, when naming transactions for the Laravel 5 framework, well-formed transaction names were being replaced by the too-generic $METHOD/index.php. This has been fixed.

  • Invoking newrelic_record_datastore_segment() before the PHP agent had connected to New Relic would result in the query callback silently failing to execute. This has been fixed; the callback will always be invoked provided parameters of the correct type are given to the function, otherwise an E_WARNING will be generated.

New Features

  • A new API function for timing datastore functions that the PHP agent doesn't natively instrument has been added: newrelic_record_datastore_segment(). Documentation and usage examples can be found on the New Relic Documentation site.

  • The agent now collects additional metadata when running within AWS, GCP, Azure, and PCF. This information is used to provide an enhanced experience when the agent is deployed on those platforms.

Bug Fixes

  • On Laravel 5.4, previous versions of the PHP agent named transactions handled by routes without explicit names based on the request method and front controller name, instead of using the route URI as with other versions of Laravel. This has been fixed, and automatic transaction names are once again consistent across all Laravel versions.

  • When generating explain plans for queries issued with MySQLi, the PHP agent could bind parameters from the wrong query if the PHP object ID had been reused internally. This has been fixed.

Wednesday, July 5, 2017 - 10:00

Bug Fixes

  • On the first request served by a PHP process, a Drupal 6 or 7 hook that was invoked with module_invoke() before it had been invoked by module_invoke_all() could have its module name reported as an empty string. This has been fixed.

  • On PHP 7.0 and 7.1, a Drupal 6 or 7 hook invoked via module_invoke_all() could report the module name as an empty string in some situations. This has been fixed.

Tuesday, June 27, 2017 - 16:50

Bug Fixes

  • Users of Guzzle 4 or 5 may have seen crashes in version 7.3.0 of the PHP agent due to a bug in the agent's request shutdown instrumentation for that library. This has been fixed.
