I am trying to create an alert that will trigger is a certain number of group members are down that would indicate a problem with the group as a whole as opposed to individual group members.
example.
I have a group of 15 servers if 5 or more servers are down trigger the alert
if (groupName.status != up && numberOfGroupNameMemberNodesDown >=5)
send alert for group
else
do nothing (I have alerts for individual nodes already)
