You probably don't have a long enough heartbeat time for your DS - thus after a delay, the data becomes unknown. If you increase the heartbeat time enough then the data will simply be normalised between updates. http://oss.oetiker.ch/rrdtool/doc/rrdcreate.en.html >heartbeat defines the maximum number of seconds that may pass >between two updates of this data source before the value of the data >source is assumed to be *UNKNOWN*. Whether this is what you want or not I don't know, but instead of a short 'blip' on the graph and nothing in between, you'll get a graph that just steps up or down at each update. -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.
