External Commands Reference - SCHEDULE_HOSTGROUP_HOST_DOWNTIME
SCHEDULE_HOSTGROUP_HOST_DOWNTIME;hostgroup_name;start_time;end_time;fixed;trigger_id;duration;author;comment
Schedules downtime for all hosts in a specified hostgroup. If the ‘fixed’ argument is set to one (1), downtime will start and end at the times specified by the ‘start’ and ‘end’ arguments. Otherwise, downtime will begin between the ‘start’ and ‘end’ times and last for ‘duration’ seconds. The ‘start’ and ‘end’ arguments are specified in time_t format (seconds since the UNIX epoch). The host downtime entries can be triggered by another downtime entry if the ‘trigger_id’ is set to the ID of another scheduled downtime entry. Set the ‘trigger_id’ argument to zero (0) if the downtime for the hosts should not be triggered by another downtime entry.
