[openstack-dev] [Horizon] [UX] Design for Alarming and Alarm Management

Hi Liz,

Looks great!

Some thoughts on the wireframe doc:

* The description of form:

    "If CPU Utilization exceeds 80%, send alarm." 
  misses the time-window aspect of the alarm definition.

  Whereas the boilerplate default descriptions generated by
  ceilometer itself:

    "cpu_util > 70.0 during 3 x 600s"

  captures this important info.

* The metric names, e.g. "CPU Utilization", are not an exact
  match for the meter names used by ceilometer, e.g. "cpu_util".

* Non-admin users can create alarms in ceilometer:

  "This is where admins can come in and
   define and edit any alarms they want
   the environment to use."

  (though these alarms will only have visibility onto the stats
   that would be accessible to the user on behalf of whom the
   alarm is being evaluated)

* There's no concept currently of alarm severity.

* "Should users be able to enable/dis-able alarms."

  Yes, the API allows for disabled (i.e. non-evaluated) alarms.

* "Should users be able to own/assign alarms?"

  Only admin users can create an alarm on behalf of another

* "Should users be able to acknowledge, close alarms?"

  No, we have no concept of ACKing an alarm.

* "Admins can also see a full list of all Alarms that have
   taken place in the past."

  In ceilometer terminology, we refer to this as alarm history
  or alarm change events.

* "CPU Utilization exceeded 80%."

  Again good to capture the duration in that description of the

* "Within the Overview section, there should be a new tab that allows the
   user to click and view all Alarms that have occurred in their environment."

  Not sure really what "environment" means here. Non-admin tenants only
  have visibility to their own alarm, whereas admins have visibility to
  all alarms.

* "This list would keep the latest  alarms."

  Presumably this would be based on querying the alarm-history API,
  as opposed to an assumption that Horizon is consuming the actual
  alarm notifications?
