[Orca-users] Re: How to customize the time axis (x-axis)?

[simon.klyne at arcordia.com]

Here's is a small Korn shell script that shows one way of graphing data for
a specific time interval from the RRD files created
by Orca:
(See attached file: report1.sh)

and here is the output:

(See attached file: 20010525_0000_Process_fail.png)(See attached file:
Performance_Report.html)

BTW I find it much easier to do this with perl, if I get time I may post a
perl script that does the same sort of thing

Hi Simon,

I am a newbie on this..Could you be a bit more specific on this
subject ?? for example, where do you place this shell script in
respect to rddtool ??

thx
