+Aplikacja pozwala dodawać, aktualizować i usuwać hosty, wybierać metodę `HTTP`/`ICMP` oraz ustawić osobny interwał i timeout. Kliknięcie hosta na liście uzupełnia formularz jego ustawieniami. Konfiguracja jest automatycznie zapisywana w pliku `hosts.json` obok aplikacji. Tabela pokazuje bieżący status, interwał, liczbę testów, liczbę odpowiedzi OK/FAIL, procent dostępności i średni czas odpowiedzi.
 
 Przycisk „Uruchom monitoring” rozpoczyna cykliczne sprawdzanie wszystkich zapisanych hostów. Wyniki są zbierane równolegle, więc wolny host nie blokuje pozostałych.
