The XML output is the current data of the metric. It didnot contal the history with it. The graph that you see in the web frontend are generated by the RRD tool and the data is archived into the RRD database. this archiving is done by the gmetad process. > > I was going through the XML output.

Also I am not able to understand the values of the tag TN, TMAX, DMAX. TN TMAX and DMAX are used for the timeout invalidation of the data value. If the Data is not refreshed for th TMAX time the data is considered to be invalid. For more information consider the help of gmetric. > 3.
