Capteurs pour les serveurs ou votre site

Vous avez surement déjà eu besoin d'un capteur qui puisse vérifier qu'un site soit toujours disponible, qu'un serveur fonctionne toujours bien ou qu'un service soit toujours démarré.

Il existe un logiciel qui réponde à ces attentes: PRTG Network Monitor par la société paessler. Vous pouvez télécharger ce logiciel ici: http://www.paessler.com/prtg/download
