Our goal is to get as much information as we can from various data
sources. If you connect Nagios to telemetry project, and we can get
nagios alarms directly from Aodh, it would be great. Is it something
that you planned on doing for Mitaka?

Our current use cases focus on giving value to the cloud admin. These
are mostly UI use cases; the admin will be able to:
- view the topology of his environment, the relations between the
physical, virtual and applicative layer and the statuses all resources
- view the alarms history (there is an existing blueprint for it)
- view alarms about problems that Vitrage deduced could happen, even
if no other OpenStack component reported these problems (yet)
- view RCA information about the alarms
In order to support these use cases, we will get input from various
data sources, process and evaluate it based on configurable templates,
trigger new alarms in Aodh and calculate RCA information.
On top of it, we will have Vitrage API to query the information and
show it in horizon.
In case you haven't seen in yet, our high level architecture is on
Vitrage main page, and in the coming days we plan to document also
the lower level design.
