Description

This tab shows the dependency tree of a host or a cluster.

It has the same behaviour as the Widget Dependency Graph.


  • The 2D tree starts from the chosen element (host or check), and displays dependency links:
  • A Node will be the representation of either a host, a cluster or a check.
  • Each element has 4 components:

 

  • Its name.
  • Its icons representing its type.
  • Its status (icon state => see the Status & Context for the list).
  • If the elements is a host, available Checks will be displayed in 4 boxes below
    sorted by their status (Critical, Warning, Unknow, Ok).
  • You can access to the “Detailed view” of this element by clicking on the eye icon.
  


  • If, in the dependency graph, there are some elements not in “OK” state, they will be listed at the bottom of the graph.
