Joe, Were all four of your graphs generated from the same RRD, or were they each from a different RRD with a different scale (i.e. hourly, rolled up to daily, rolled up to monthly, etc.?)
In my case, I have data collected and stored in 1 second slots. Thus, a one-day graph would have 86,400 slots. When graphing, I might use the entire RRD or just a subset of the domain (such as the last 10 minutes - 600 slots, by specifying appropriate parameters for --end and --start). What I've found is unless I "zoom in" enough (restrict the graph's domain using --end and --start), the VRULEs aren't drawn. My suspicion is that if the domain gets too large, rrdtool graph will not display the VRULEs, as they have a fixed "width" of one slot (e.g. one second, in my case). How does this compare to what you've been doing? Thanks, - Chris Joe Loiacono wrote: > I have had a different experience.
