Applications – software applications – mean a specific thing in IT. Usually, that’s a user-oriented piece of software. A web browser, word processor, game. Lately, mobile applications have somewhat lowered the bar, even down to I Am Rich applications.
And then there’s Zabbix with it’s own definition for applications. So what are applications in Zabbix?
So you had a cluster monitored. As is common with clusters, you wanted to have some cluster-wide parameter adding. Average CPU load, number of nodes online – something not tied to a single cluster node, thus you created a special host to denote the whole cluster. Then you went to that host, clicked “Create trigger”, specified all the items on individual cluster hosts, clicked “Add”… and the trigger was not there. Mysteriously missing.
Oh, wait. That trigger actually appeared on all the cluster hosts. Is this a bug?
