Custom Parameters Support via PHP Agent API

This PHP API is a key and a value pair that allows you to keep track of the parameters within a transaction. This gives deeper visibility into your own application methods.

To add a custom parameter, follow the syntax given below:

Syntax:

zpa_custom_params(“Key”,Value);

Parameter Name	Description
Key	The name of the custom parameter you want to track for a particular transaction/request.
Value	The value of the custom parameter you want to track. It can be any of the below types, int, float, long, double, bool, decimal or string.

Example:

The following method illustrates how the parameters are tracked via API,


function trigger_application_update(){
 //Your application code...
 
 $app_version = get_bloginfo( 'version' );
 $user_name = wp_get_current_user();
zpa_custom_params("Version",$app_version);
 zpa_custom_params("UserName",$user_name->display_name);
 zpa_custom_params("Action","Triggered update");
//Your application code...
}

The added parameter values will be displayed as follows under Traces > Summary > Custom Parameters:

Custom parameters

Custom parameters can be found only if the transaction has an error or if the trace is populated for that transaction.
