Graph are usually part of a probe. But some might want to add custom graph, that use data from different graph, or display values in a different way.
So it's possible to add in the configuration some graph description.
In this graph description, one can add a path using a
addpath element instead of a
add one :
<addpath> <path> <host>host</host> <probe>probe</probe> <dsName>datasource name</dsName> </path> ... </addpath>
Another kind of custom graph is the aggregate. It takes a set of same kind graph and combine their values using the provided function. As the time of writing, only one kind of aggregation is provided, a sum. A sum custom graph is defined in a sum file :
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE sum PUBLIC "-//jrds//DTD Sum//EN" "urn:jrds:sum"> <sum name="sum name" id="sum id"> <element name="graph 1 name" /> <element name="graph 2 name" /> </sum>
All custom graph appears in the
Custom graphs id, or the id can be used to add them in a custom tab.
