Hi,

Currently, oVirt is intelligent to understand the relationship hierarchies of various entities in the system, and even allows setting permissions based on this hierarchy. Can this information further be used to enhance the health monitoring of various entities in the system? Let me take an example.

Consider this hierarchy (gluster):

System -> Cluster -> Volume -> Brick

If one or more bricks of a volume are down, which indicates a problem, following entities should be overlaid with a warning symbol (say, a yellow exclamation mark) - Volume to which the brick(s) belong(s) - it's parent cluster - System

This helps in highlighting what parts of the system are affected by failures/problems at the lowest level entities, and gives a better idea of the overall health of the entire environment to the administrator.

Thoughts?

interesting idea. i wonder if the tree could represent this, and if it would require some refresh for status to update. i wonder if the scheme should be based on status of entities, which requires specific logic, or on some sort of an alert like mechanism (since alerts are similar to "problems" which you describe above). then you can leverage the fact events/alerts include all entities in the hierarchy, so very easy to highlight an entity as with an "issue/alert/problem" based on it having any open alerts/problems.
