I want to be able to create a history of cpu usage. Everyday I want a cron job or some oher method to generate a graph image and save it to disk.

These graphs can be used to track the history of the server over a longer time than 48hours.

I thought the attached url explains a method that can generate the graphs for me.

Hi all,

I want to generate some hobbit / xymon graphs every day. I have been trying to get the following url to work but it keeps failing.

Please can some one tell me (I am not a web master) how to get an image generated such as image01.jpg.

http://www.docum.org/foswiki/bin/view/Xymon/DebugGraphs

I created a file in the cgi directory, add the config and my url. made it executable and ran it using the command but I get. You don't have to create a file in the cgi directory.  So, what exactly do you want to do and what have you tried ?

All the data is stored every few minutes. If you want to see it from a certain time period, you just zoom in. Does that not work for what you need?

If and when you zoom in and find the graph for the time period you want, using Firefox you just right click on the background, go to View Page Info and click Media at the top. You'll find the image in the list here. Note right-clicking the image will make it zoom out.

If you right click on a graph and select the link (it depends on the browser you use), you can use wget to save the graphs daily. On the other hand, why ? There are 4 graphs dispayed and you can zoom in on the graphs if you want more detail.

If I am asked to show the cpu usage for 25th feb 2009 hobbit can not do it.

I need to have an automated method of saving the images, as I do not wish to right click and save over 50 images every day, for CPU alone.

this must be an automated process, then I get use perl to generate reports with this data.

I have script that increses the data points from 576 to 5760 so you have more datapoints the rrd file and you can zoom more in detail.  The rrd files are bigger in size, but disk space is not so expensive.
