Nie raz potrzebujemy zinwentaryzować maszyny wirtualne na posiadanym klastrze. Jeśli mamy SC VMM to problemu większego nie ma, gorzej gdy trzeba to zrobić ręcznie.
Spisanie 2-3 maszyn to nie problem, ale jak mamy ich setki i chcemy sobie zrobić zestawienie maszyn, dysków, kart sieciowych – ręczna robota zajmie nam nawet wiele godzin 🙂
Też miałem ten problem, więc napisałem prosty skrypt, który generuje czytelny dokument HTML zawierający wszystkie istotne informacje o naszym środowisku. Skrypt przyda się również, jeśli będziemy musieli zinwentaryzować środowisko klienta i przeprowadzić prostą analizę czy jest ono poprawnie ustawione.
Skrypt nie wymaga dodatkowej konfiguracji o ile włączymy go na hoście będącym członkiem klastra Hyper-V. Skrypt musi być uruchomiony z prawami lokalnego administratora
Czekam na komentarze…
