Is there a WordPress hook I can use to run a function anytime any plugin is updated?

I am trying to write to a log file with the logged in users IP every time something is updated so I can track activity.

Maybe upgrader_process_complete() action hook.

Fires when the bulk upgrader process is complete.

On line 761 of wp-admin/includes/class-wp-upgrader.php

From source:

/**
 * Fires when the upgrader process is complete.
 *
 * See also {@see 'upgrader_package_options'}.
 *
 * @since 3.6.0
 * @since 3.7.0 Added to WP_Upgrader::run().
 * @since 4.6.0 `$translations` was added as a possible argument to `$hook_extra`.
 *
 * @param WP_Upgrader $this WP_Upgrader instance. In other contexts, $this, might be a
 *                          Theme_Upgrader, Plugin_Upgrader, Core_Upgrade, or Language_Pack_Upgrader instance.
 * @param array       $hook_extra {
 *     Array of bulk item update data.
 *
 *     @type string $action       Type of action. Default 'update'.
 *     @type string $type         Type of update process. Accepts 'plugin', 'theme', 'translation', or 'core'.
 *     @type bool   $bulk         Whether the update process is a bulk update. Default true.
 *     @type array  $plugins      Array of the basename paths of the plugins' main files.
 *     @type array  $themes       The theme slugs.
 *     @type array  $translations {
 *         Array of translations update data.
 *
 *         @type string $language The locale the translation is for.
 *         @type string $type     Type of translation. Accepts 'plugin', 'theme', or 'core'.
 *         @type string $slug     Text domain the translation is for. The slug of a theme/plugin or
 *                                'default' for core translations.
 *         @type string $version  The version of a theme, plugin, or core.
 *     }
 * }

do_action( 'upgrader_process_complete', $this, $options['hook_extra'] );

This below is just the example from codex (it is noted as untested there, btw), and I edited it to show a possible instance of all plugin updates:

add_action( 'upgrader_process_complete', 'my_upgrate_function',10, 2);

function my_upgrate_function( $upgrader_object, $options ) {


    if ($options['action'] == 'update' && $options['type'] == 'plugin' ) {

       foreach($options['packages'] as $each_plugin) {

             // do stuff

       }//end foreach
    }//end if
}//end my_upgrade_function()
