Hi,
I have an application named XYZ (http monitor) running in 3 servers:
server_A , server_B and server_C.
Please help me to create an alert to triggering only when:
Application XYZ is down in these 3 servers.
Thanks alot.
You can try the following example alert trigger.
you could also try to take a look into APM-groups.
You can create a group like "Company Website Cluster", include these monitors in that group and alert if all items in the group are down.
that way you will not need to edit the alert for new/removed servers but will need to add/remove it directly from the group (this can be done automagically with a dynamic query I believe).
Agreed, Grouping is the best way to achieve this I think. I'm not even sure aLTeReGo's trigger would work as it can never match more than one node AFAIK (as the trigger is run against database node rows and therefore impossible to match more than one at once?).
