<div>I added in User and Project to the table.</div><div><br></div><div>I’m still trying to work it out in my head if it would make sense to users to have a field in the Alarm Management table for “Current State”. Wouldn’t they just look at the Alarm History? What if an Alarm was triggered a while ago and the user doesn’t care about this anymore, but it is still shown in the table as “Triggered”. The user doesn’t get information like how many times in the past day has this alarm been triggered unless they look at the alarm history. Also, I’m not sure what the user would get from being able to see other states like Alarm Ready. Would we even allow an Alarm with “insufficient data” to be saved? Do you have an example of this? Sorry for all of the questions here, just trying to make sure it will be understandable for all users :) For now, I’ve added an icon denoting whether or not the alarm has been triggered in the last 24 hours (so in the wireframe this would be Alarms 1 and 2).</div></div></div><div><br></div><br><blockquote type="cite"><div lang="EN-US" link="blue" vlink="purple" style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;"><div class="WordSection1" style="page: WordSection1;"><div style="margin: 0in 0in 0.0001pt 0.5in; font-size: 12pt; font-family: 'Times New Roman', serif; text-indent: -0.25in;"><span style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125);"><o:p></o:p></span></div><div style="margin: 0in 0in 0.0001pt 0.5in; font-size: 12pt; font-family: 'Times New Roman', serif; text-indent: -0.25in;"><span style="font-size: 11pt; font-family: Symbol; color: rgb(31, 73, 125);"><span>·<span style="font-style: normal; font-variant: normal; font-weight: normal; font-size: 7pt; line-height: normal; font-family: 'Times New Roman';"> <span class="Apple-converted-space"> </span></span></span></span><span style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125);">I would add a “delete alarm” button as a table action</span></div></div></div></blockquote><div><br></div><div><!--?xml version="1.0" encoding="UTF-8" standalone="no"?-->

The point here is to show any Alarms that have occurred to notify the user. Other notification ideas could be to allow users to get notified of alerts via e-mail (perhaps a user setting?). I’ve added a wireframe for this update in User Settings. Then the Alarms Management section would just be where the user creates, deletes, enables, and disables alarms. Do you still think we don’t need the “alarms” tab? Perhaps this just becomes iteration 2 and is left out for now as you mention in your etherpad.</span><o:p></o:p></div></div><div><div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;"><o:p> </o:p></div></div><div><div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;"><span style="font-family: Arial, sans-serif;">5) Question about combined alarms…currently I’ve designed it so that a user could create multiple levels in the “Alarm When…” section.

Recall that meters are per-resource-instance, so in the simplest case an alarm might be defined over a particular meter applied to all resources visible to a particular user. More useful however would the option to explicitly select which specific resources we're interested in alarming on. On one extreme we would have narrowly dimensioned alarms where this selection would have only a single target (identified by resource ID). On the other extreme, we'd have widely dimensioned alarms where this selection identifies many resources over which the statistic is aggregated, for example all instances booted from a particular image or all instances with matching user metadata (the latter is how Heat identifies autoscaling groups)."<br><br>We'd have to think about how that concept is captured in the<br>UX for alarm creation/update.<br><br>Second, there are a couple of more advanced alarming features<span class="Apple-converted-space"> </span><br>that were added in Icehouse:<br><br>1. The ability to constrain alarms on time ranges, such that they<br> would only fire say during 9-to-5 on a weekday. This would<br> allow for example different autoscaling policies to be applied<br> out-of-hours, when resource usage is likely to be cheaper and<br> manual remediation less straight-forward.<br><br>2. The ability to exclude low-quality datapoints with anomolously<br> low sample counts. This allows the leading edge of the trend of<br> widely dimensioned alarms not to be skewed by eagerly-reporting<br> outliers.<br><br>Perhaps not in a first iteration, but at some point it may make sense<br>to expose these more advanced features in the UI.<br><br>Cheers,<br>Eoghan<br><br>[1]<span class="Apple-converted-space"> </span><a href="http://openstack.redhat.com/CeilometerQuickStart" style="color: purple; text-decoration: underline;">http://openstack.redhat.com/CeilometerQuickStart</a><br><br><br><br>----- Original Message -----<br><br><o:p></o:p></div><blockquote style="margin-top: 5pt; margin-bottom: 5pt;"><div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;"><br>Hi Liz,<br><br>Looks great!<br><br>Some thoughts on the wireframe doc:<br><br>* The description of form:<br><br> "If CPU Utilization exceeds 80%, send alarm."<br><br>misses the time-window aspect of the alarm definition.<br><br>Whereas the boilerplate default descriptions generated by<br>ceilometer itself:<br><br> "cpu_util > 70.0 during 3 x 600s"<br><br>captures this important info.<br><br>* The metric names, e.g. "CPU Utilization", are not an exact<br>match for the meter names used by ceilometer, e.g. "cpu_util".<br><br>* Non-admin users can create alarms in ceilometer:<br><br>"This is where admins can come in and<br> define and edit any alarms they want<br> the environment to use."<br><br>(though these alarms will only have visibility onto the stats<br> that would be accessible to the user on behalf of whom the<br> alarm is being evaluated)<br><br>* There's no concept currently of alarm severity.<br><br>* "Should users be able to enable/dis-able alarms."<br><br>Yes, the API allows for disabled (i.e. non-evaluated) alarms.<br><br>* "Should users be able to own/assign alarms?"<br><br>Only admin users can create an alarm on behalf of another<br>user/tenant.<br><br>* "Should users be able to acknowledge, close alarms?"<br><br>No, we have no concept of ACKing an alarm.<br><br>* "Admins can also see a full list of all Alarms that have<br> taken place in the past."<br><br>In ceilometer terminology, we refer to this as alarm history<br>or alarm change events.<br><br>* "CPU Utilization exceeded 80%."<br><br>Again good to capture the duration in that description of the<br>event.<br><br>* "Within the Overview section, there should be a new tab that allows the<br> user to click and view all Alarms that have occurred in their<br> environment."<br><br>Not sure really what "environment" means here.
