Subject: [Hawkular-dev] Business app/services representation in Inventory
Hi
Before going too far down the BTM road, I just wanted to confirm whether or
not we want the business app, their components services, and their
relationships to IT resources they use, stored in Hawkular Inventory?
Inventory definitely is the right place to store such information.
An alternative approach would be to derive the structure and
relationships
dynamically from the business transaction instance information.
Deriving the structure and relationships dynamically is basically
a "discovery" as called in ye olde RHQ days. That is a capability
which we'd very much like to keep.
The new inventory is (so far) unaware of special "discovery" step - everything
from resource creation to establishing relationships is done through 1 public
API that "anyone" can use.
The benefit of storing in Inventory is it enables end users to
navigate
through the inventory to understand the relationships to the business
apps/services, as well as allow other tooling (e.g. impact analysis) to
determine the effect of IT resource downtime on business apps.
+1. I know Brett will object that that's what Artificer is for, too, but I
personally see the difference in Inventory's focus on relationships, while
Artificer is more geared towards managing content.
Thoughts?
Regards
Gary
