What is the most effective way to monitor a clustered app or system composed of many components.
Say I have a system consisting of three clustered servers. Is there a way to receive a warning notification if one or 2 of the 3 server has a problem *Degraded situation), and an ALERT/DOWN status if the 3 servers are down ?
I guess we can do this with dependencies, but I find the concept a bit difficult to grasp in PRTG. I mean, is there a documentation with real world example of how it works ?
Same question with business apps. We are trying to produce a dashboard for the managers, where we want to show them items which are more easy to understand than servers names. For example: If web server x, database server cluster y or reverse-proxy z are in trouble, the business application ABC is in trouble. For the managers, the view we have to offer, is a vies consisting of "business services", not server names (they have no idea what they are)
Is there a way to present a dashboard with names different than servers ? Some sort of aggregate view which use more "business" terms than technical terms ?
