Stacking example
The below configuration shows how to create a stacked graph from a data source (namely the entropy value) from two hosts.
The example creates a virtual host ("aggregates.example.com") under which we loan data values from the two other hosts, and then creates a stacked graph from the same hosts.
Note that the two individual graphs are not necessary to create the stacked graph, they're only there for reference.
[aggregates.example.com] update no contacts no # This graph loans data values from foo.example.com to be graphed under aggregates.example.com # This is not required to create the stack graph below, but is nice for reference foo_entropy.graph_order entropy=foo.example.com:entropy.entropy foo_entropy.update no foo_entropy.graph_category System foo_entropy.graph_title Entropy on foo # This graph loans data values from bar.example.com to be graphed under aggregates.example.com # This is not required to create the stack graph below, but is nice for reference bar_entropy.graph_order entropy=bar.example.com:entropy.entropy bar_entropy.update no bar_entropy.graph_category System bar_entropy.graph_title Entropy on bar # This graph stacks the entropy values from the hosts foo.example.com and bar.example.com total_entropy.update no total_entropy.graph_args --base 1000 -l 0 total_entropy.graph_category System total_entropy.graph_title Aggregated entropy, completely bogus total_entropy.total_received.label not_used total_entropy.total_received.stack \ foo=foo.example.com:entropy.entropy \ bar=bar.example.com:entropy.entropy
The last part of the above configuration gives a stacked graph, like this:
If you need to reference a node with you have specified a group name for manually, then you also need to enter the node name with the group name like "Group;node.name" where the node is referenced.
