Jay Buffington commented on AURORA-653:
---------------------------------------
[~wfarner] and [~bhuvan] pointed me to http://aurora-scheduler/vars which has
values like this for production jobs:
{code}
sla_{{jobkey}}_platform_uptime_percent 100.0
{code}
[~evanroode] it seems like this gives you what you want to be able to
"determine the health of an app, as in the ratio of how many instances are
running and how many instances were configured to run"
> Make Job.instances value available through the IDL

> Project: Aurora
> Issue Type: Story
> Components: Scheduler
> Reporter: Erik van Roode
>
> Why:
> I would like to be able to determine the health of an app, as in the ratio
> of how many instances are running
> and how many instances were configured to run (Job.instances).
> I can find the "Active" number in various places, but I cannot find the
> "Configured" anywhere.
> As far as I can tell every instance of "Instances/instanceCount" is actually
> the number of active jobs/tasks.
> Eg, JobConfiguration contains instanceCount, but it is not Job.instances.
> I created a job with 5 instances,
> killed one, and instanceCount dropped to 4.
