Tagging

you may want to attach your own custom tags to entries. To accomplish this, you may use the Telescope::tag method.

Filtering

You may only want to record entries under certain special conditions. To achieve this, you may use the Telescope::filter method.

Example

use FriendsOfHyperf\Telescope\Telescope;
use Hyperf\Event\Contract\ListenerInterface;
use Hyperf\Framework\Event\BootApplication;
use FriendsOfHyperf\Telescope\IncomingEntry;

class TelescopeInitListener implements ListenerInterface
{
    public function listen(): array
    {
        return [
            BootApplication::class,
        ];
    }

    public function process(object $event): void
    {
        // attach your own custom tags
        Telescope::tag(function (IncomingEntry $entry) {
            if ($entry->type === 'request') {
                return [
                    'status:' . $entry->content['response_status'],
                    'uri:'. $entry->content['uri'],
                ];
            }
        });

        // filter entry
        Telescope::filter(function (IncomingEntry $entry): bool {
            if ($entry->type === 'request'){
                if ($entry->content['uri'] == 'xxxx') {
                    return false;
                }
            }
            return true;
        });

    }
}

You can also do this in middleware.
