Knowledge is Power. Be it war, peace, administration or day-to-day business, information about any dynamic parameter you are dealing with, adds to your strength. Imagine a day when you are idly playing a video on Youtube, and out of the blue comes a popup screaming - “Dude, you’ve got a problem. MySQL is kinda acting weird, and the server load is leaping over the moon. You better check it right away!!” Aaaah!! Life would have been so much easier! If this is what you have been dreaming about, this is exactly what Nagios can deliver.
