Answer 1

重写类OwenIt\Auditing\Resolvers\UserAgentResolver，

audit.php

    'resolver'    => [
       ...
        'user_agent' => App\Resolvers\UserAgentResolver::class,
       ...
    ],

App\Resolvers\UserAgentResolver.php

class UserAgentResolver implements \OwenIt\Auditing\Contracts\UserAgentResolver
{
    /**
     * {@inheritdoc}
     */
    public static function resolve()
    {
        return 'Prefix-'.substr(
            Request::header('User-Agent'), 0, 50
        ).'-Suffix';
    }

}
