I need to monitor my clients servers and desktops. Servers are either Win2000 or 2003 and desktops are either XP or Vista. They want 24x7 monitoring and if something goes down I would need to be alerted via email or cell phone. I am geting more of my clients requesting the 24x7 monitoring so thought I would look into finding a solution, but there is so much out there. I want something very user friendly and cost effective. My customers want everything for nothing$. Has anyone used Power Admin / PA Server monitor? That one looked pretty user friendly and was only $99/server. The bad thing about that one is I do not think it does desktops and I would like to use the same software for both server and desktop. I will need to sit at my office and check the monitoring logs and reports of my clients so I will need remote monitoring. What is the best software out there???
