Hello everyone,

I am in the process of implementing Ceilometer Alarm API. Here are the 
blueprints.

https://blueprints.launchpad.net/horizon/+spec/ceilometer-alarm-api
https://blueprints.launchpad.net/horizon/+spec/ceilometer-alarm-management-page


While I am waiting for some Ceilometer patches to complete, I would like 
to start a discussion about the bp. 
https://blueprints.launchpad.net/horizon/+spec/ceilometer-alarm-management-page:

1. The points 1-4 from are some sort simple version of the page, that 
uses all basic alarm-api features. Do you think we need them all? Any 
feedback for them? Enhancements?

2. There is a thought, that we should maybe divide Alarms into (System, 
User-defined). The only system alarms now, are set up with Heat and used 
for auto-scaling.

3. There is a thought about watching correlation of multiple alarm 
histories in one Chart (either Alarm Histories, or the real statistics 
the Alarm is defined by). Do you think it will be needed? Any real life 
examples you have in mind?

4. There is a thought about tagging the alarms by user defined tag, so 
user can easily group alarms together and then watch them together based 
on their tag.

5. There is a thought about generating a default alarms, that could 
observe the most important things (verifying good behaviour, showing bad 
behaviour). Does anybody have an idea which alarms could be the most 
important and usable for everybody?

6. There is a thought about making overview pages customizable by the 
users, so they can really observe, what they need. (includes Ceilometer 
statistics and alarms)

Could you please give me some feedback for the points above(or anything 
else related)? After we collect what we need, I would push this to UX 
guys, so they can prepare some wireframes of how it could look like. So 
we can start discuss the UX.
e.g. even the Alarm management from 1 could be pretty challenging, as we 
have to come up with some sane UI, for defining general statistic query, 
that defines the Alarm.

Thank you very much for any feedback.
