How to get all of the activate_plugin action parameters?

I am trying to hook into activate_plugin.

I know that activate_plugin has 1 required param and 2 optional ones. I am trying to acquire all 3.

Here’s my setup:

// create plugin settings menu
add_action('admin_menu', 'pe_create_menu');

function pe_create_menu() {

  //create new sub-level menu
  add_submenu_page( 'plugins.php', 'Plugin Settings', 'Plugin Enabler', 'administrator', __FILE__, 'pe_settings_page' );

  // Add my hook
  add_action( 'activate_plugin', 'pe_network_activate', 10, 3 );
}

And my function:

function pe_network_activate( $plugin, $redirect = '', $network_wide = false ) {
  $args = var_export( func_get_args(), true);
  _log("Args: " . $args); // write to the WP error_log
}

$args returns only the first parameter. How do I get all 3?

My goal is to be able to tell when a plugin is being network activated, or just normally activated – hence the need for $network_wide.
