sla_list_safe_domain
Usage: sla_list_safe_domain --cluster=cluster --attribute={rack | host}
percentage duration [--override_jobs=filename]
[--exclude_attr=filename][--list_jobs]
Returns a list of racks or hosts where it would be safe to kill tasks without
violating their job SLA: percentage of tasks that stayed up within the last
“duration” secs|mins|hrs|days. The SLA can be specified globally per cluster as
pair of percentage and duration values or per job in a file.
--cluster:
Aurora cluster name.
--attribute:
Currently supported attributes “host” or “rack”.
percentage:
Percentage of tasks required to be up within the duration. Applied to all jobs
except those listed in --override file.
duration:
Time interval (now - value) for the percentage of up tasks. Applied to all jobs
except those listed in --override_jobs file. Format:
<value>{secs|mins|hrs|days}.
--override_jobs:
An optional file to load job specific SLAs that will override cluster-wide
command line percentage and duration values. The file can have multiple lines
in the following format:
role/env/job percentage duration
--exclude_attr:
An optional text file listing attribute values (one per line) to exclude from
the result set if found.
--list_jobs:
Lists all affected job keys with projected new SLAs if their tasks get killed.
Examples:
sla_list_safe_domain --cluster=smf1 --attribute=host 85 10mins
sla_list_safe_domain --cluster=smf1 --filename=~/rack.txt
