Dependencies What are dependencies and how do they work?

(How to access this screen? Edit-Dependencies)

If we concider this (simple) network diagram, we will check the router and the webserver via Servers Alive.
From the dependecies, we will set that the webserver (slave) depends on router (master)
Check cycle 1

Check cycle 2 Check cycle 3 Check cycle 4 If we wouldn't use the dependencies, then in cycle 3, both the router and the webserver would have been checked and marked as down. Even if the webserver was up but unreachable (unavailable) from our point of view.
