Connect the agent to other New Relic products

The PHP agent integrates with other New Relic products to give you end-to-end visibility:

Product Integration
New Relic Browser The PHP agent automatically injects the Browser JavaScript agent when you enable auto-instrumentation. After enabling Browser injection, you can view Browser data in the APM Overview page and quickly switch between the APM and Browser data for a particular app. For configuration options and manual instrumentation, see New Relic Browser and the PHP agent.
New Relic Infrastructure When you install the Infrastructure and APM agents on the same host, they automatically detect one another. You can then view a list of hosts in the APM UI, and filter your Infrastructure hosts by APM app in the Infrastructure UI. For more information, see New Relic APM data in Infrastructure.
New Relic Insights The PHP agent sends default events and attributes to Insights for NRQL queries. You can also record custom events for advanced analysis.
New Relic Synthetics Synthetic transaction traces connect requests from Synthetics monitors to the underlying APM transaction.
