[hobbit] Help with Graphing peak values

[Myers, Timothy L.]

While you in there for my use the best change would be if you take the data average over a period put it in a Sunday - Saturday array and plot the average by hour or 5 min segment for a 7 day work week.  This view would give a work week load graph that would help on load balancing scheduled tasks and new project in the work week.
 
I am new to this wonderfully tool (Hobbit) and still trying to understand the basics.  I don't know yet how easy it is to filter the data or extract and create a new database.  I would assume that pulling the data periodically and building a summary database would be the easy approach. Another approach would be to build a day of the week data base with the same data as the load data.  I don't know yet if the graphing tool has a adequate summary function for the task given day of the week, hour, time, date, load order. 
 
Right now I have more questions than answers, I will be reading and testing to get my answers but in the mean time I thought I would add my suggestion as long as your research is already headed that way.

Hello hobbit users,
 
I am looking at changing the graph for load average (if possible). Actually, this applies to a few of the graphs.
 
Typically, our systems are very busy during the day yet at night are mostly idle (load average of around 10 to 12. When you look at the graphs produced from a capacity planning perspective, for the last 48 hours, you get accurate values, but from a 576 day graph, the load average is much lower as it is taking into account the out of hours period.
 
I was thinking it would be nice to see a line plotted on the same graph showing the peak value for the sample rather than the average.
 
I have been reading through rrdtool man pages but every change I make seems to stop the graphs being produced.
 
Ideas?
 
Thanks
 
Phil
