Exclude dead devices from Dashboard

Hi Anil,

One way to do this would be to dynamically group devices and exclude dead devices, then have the dashboard reference that dynamic group.  So, as an example, you could group together all non-terminated EC2 instances with the kay value tag pair 'env:prod' with this dynamic group query: system.aws.tag.env == "prod" && system.aws.stateName != "terminated".  Dashboards configured to match this dynamic group will display data for all non-terminated EC2 instances with that key value tag pair.  

Thanks,
Sarah
