[Orca-users] Re: writing data to my input file to orca if no new data is found

Blair - 

Thanks so much for your quick response.

I'm definately noticing the blank area(s) in the graphs when there is
no data, however, the "percentages" stay at 100% as the calculation
seems to only use data that is collected. I want orca to write a line
to the data input file (if it finds that no new data arrived) so that
it will use the zeroes in calculating a more accurate percentage of
uptime.

i.e. it seems like there is logic in orca to check if the data has
been updated since the loop, before it attempts to generate graphs
again. If it determines there was no new data, it skips creating the
graphs, correct? Couldn't I just tell it to append a dummy line to my
data input file at that point?

Here's a sample of my data input file...
# tail -5 tabloid.uptime
954183802 100 100
954183922 100 100
954184043 100 100
954184163 100 100
954184283 100 100

As I'm new to programming, I'm having trouble following the logic of
orca program. i.e. I noticed there are multiple subroutines called
"new." How can there be multiple subroutines with the same name?
Wouldn't this confuse perl? Is there a perl book you can recommend
that would help me to better understand?

I apologize for all of the questions but my "Learing Perl" book is
not much help.

Thanks again.

Regards,
Jeff
