We are planning to switch from currently installed zabbix 2.0.1 to latest version.
There is custom graph which aggregates few metrics from hosts in one group. Graph created and associated with one of these hosts. Problem is that this graph also becomes shared between all hosts from which metrics are added to graph. This problem occurs upon export/import phase of upgrade of zabbix and expressed in cross-host metric dependencies.
Is there any zabbix-idiomatic way to create such graph which will be free from dependency problem? Or there is only way in which we should delete graph in old installation, upgrade and then create it again?
