I am trying to create an aggregate graph of two items from a dozen different hosts. This is successful if I create the graph in one of the monitored hosts. However, you then have a graph title showing that host, which makes it seem more important that the other 11 hosts in the graph. So what I tried was to setup a "dummy host" that doesn't really exist, kind of like happens with web checks. Then I tried to create the graph from within that host. But Zabbix won't link the graph to the dummy host, and instead links it to the host listed first alphabetically. Any ideas on how to do this?
