When creating custom events, follow these rules:

  • The agent records a maximum of 10,000 events per minute. Limit the number of unique event type names that you create, and do not generate these names dynamically.

  • Avoid using reserved words and characters for the event and attributes names.
  • Ensure you do not exceed the event size and rate restrictions.


Parameter Description



Required. Name of the custom event.



Required. Supply custom attributes as an associative array. Supply the attribute names as keys of up to 255 characters, and supply the values as scalar values. Arrays and objects are not supported.


Basic example

if (extension_loaded('newrelic')) { // Ensure PHP agent is available
    newrelic_record_custom_event("WidgetSale", array("color"=>"red", "weight"=>12.5));
