The PHP agent captures special metrics for WordPress websites. When these metrics are collected, a WordPress tab appears in the New Relic user interface: Go to rpm.newrelic.com/apm > (select a WordPress app) > Monitoring > WordPress.
The collection of WordPress-specific metrics can be controlled by the ini setting
newrelic.framework.wordpress.hooks. It is enabled by default (in versions 5.3 or higher), and can be disabled with:
newrelic.framework.wordpress.hooks = false
Though this setting uses the word "hooks," it controls the collection of all WordPress metrics: hooks, plugins, and themes.
The PHP agent collects metrics for the following:
- Hooks: These metrics indicate time spent within each WordPress hook. Time is calculated from the hook dispatch functions
do_action, and do_action_ref_array.
- Plugins and themes: These metrics indicate time spent within each WordPress plugin and theme. Time is calculated from the hook dispatch functions above.
Integration with New Relic partners
By integrating your WordPress application with New Relic APM, you can view performance directly from your Wordpress app's Administration page. For example, W3 Total Cache is one of New Relic's Connect partners that specializes in WordPress apps.
WordPress plugin for browser monitoring
Signing up for a New Relic account and adding New Relic Browser monitoring to your WordPress site is fast and easy with the New Relic Browser plugin for WordPress. This plugin, and New Relic Browser monitoring, do not require the special access required to install the New Relic APM PHP agent. This makes them generally compatible with all WordPress hosting providers.
This plugin is supported by the authors and the WordPress community.
