WordPress specific functionality

If you install New Relic for WordPress websites, the PHP agent receives additional metrics. A WordPress page appears in the New Relic user interface: Go to one.newrelic.com > APM & services > (select a WordPress app).

Configuration

You can control which WordPress-specific metrics your app sends to New Relic by using the PHP agent's ini setting newrelic.framework.wordpress.hooks. This is enabled by default in versions 5.3 or higher, and it can be disabled with:

newrelic.framework.wordpress.hooks = false

Although this setting uses the word .hooks, it controls all WordPress metrics sent to New Relic, including hooks, plugins, and themes.

Metrics

The PHP agent receives metrics for the following:

• Hooks: These metrics indicate time spent within each WordPress hook. Time is calculated from the hook dispatch functions apply_filters, apply_filters_ref_array, 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 dispatch functions for hooks.

Integration with New Relic partners

By integrating your WordPress application with APM, you can view performance directly from your WordPress app's Administration page. For example, W3 Total Cache is one of New Relic's partners that specializes in WordPress apps.
