Graphs
Graphs are the abstraction of a single chart generated by NetMRG using RRDTOOL. Graphs have properties such as sizes, a title, and vertical labels. They also contain a set of Graph Items which represent the separate pieces of data graphed.
Custom Graphs
Custom graphs have "absolute" referencing of data to be displayed. They are typically used for graphs that are applicable in only one instance, such as a stack graph of all Internet links on your network.
Templated Graphs
Template Graphs have "relative" references to data. They are used for graphs such as CPU load on a server or traffic on a network interface. They are applicable in many instances. The use of templates allows you to create one graph for a set of variables on a Sub-Device and then apply that same graph to other Sub-Devices for graphs formatted identically. This allows considerable savings of time as there is no need to create a Custom Graph for each instance of a graph.
Graph Items
Graph Items represent data on a graph. They can represent areas, lines, and stacks on Graphs. Each Graph Item is linked to a Monitor for dynamic data or given a static value. Options for Graph Items include type (such as line, area, stack), color, value (either static or dynamic based on a Monitor), and legend options.
