[Orca-users] Re: Format of input file for Orca

[Blair Zajac]

Hi Einar,

You should be able to read this data in pretty easily.  Use the
orcallator/orcallator.cfg.in file as a basis to start writing your
own Orca configuration file for your data.

The one thing you will need to change is the lines

    column_description      first_line
    date_source             column_name timestamp

to something like

    column_description      date time hostname count epoch
    date_source             epoch

and then for a plot of this type

plot {
.
.
data count
.
.
}

This should be enought to get you started.

Regards,
Blair
