cluster percentage duration
Returns a list of relevant hosts where it would be safe to kill
tasks without violating their job SLA. The SLA is defined as a pair of
percentage and duration, where:
percentage - Percentage of tasks required to be up within the duration.
Applied to all jobs except those listed in --override_jobs file;
duration - Time interval (now - value) for the percentage of up tasks.
Applied to all jobs except those listed in --override_jobs file.
Format: XdYhZmWs (each field is optional but must be in that order.)
Examples: 5m, 1d3h45m.
NOTE: if --grouping option is specified and is set to anything other than
default (by_host) the results will be processed and filtered based
on the grouping function on a all-or-nothing basis. In other words,
the group is 'safe' IFF it is safe to kill tasks on all hosts in the
group at the same time.
