Please point me to the right place for instructions -- how to create a chart that is not host-bound?
(analog in cacti -- graph, which has host: none )?
An attempt to make a template, and create a graph in it - failed, you can not select the hosts from which to take the values ​​...
Thanks in advance!

Answer 1

Create an "empty" host. Go to "Charts" and when creating a graph, when selecting a data element, select any host.
