>From the error message I would guess it could be either a bad data point or
some problem with the RRD module.
 If you give three '-v' options to Orca ('-v -v -v') then orca displays the
data points as it reads them in.  If there is a corruption in your data
this should show it.

Failing that you could try upgrading your RRDs perl module - I don't know
of any issues with RRDs 1.000131
but I just recreated your config and tested it and I get plots from the
small amount of data you provided.
I have the same version of Orca - 0.26beta1 but I have a newer RRDs module
- 1.000241

Does anyone else know of any issues with RRD ?

Thanx for the help. I have already changed that, and the situation doesn't
look so bad, but I still have no PNGs.
I would like to show you my files, and I hope that you can help me.

This is my cfg file "orca_ping.cfg":

group orca_ping {
find_files              /usr/local/var/orca/orcallator/monitoring_ping
column_description      first_line
date_source             column_name timestamp
date_format             %s
interval                120
reopen                  1
....

plot {
title                   %g Avg Ping-Time for panda
source                  orca_ping
data                    ping_avg
plot_width              400
plot_height             350
legend                  ping zeiten
color                   ff0000
y_legend                Number Processes
href
http://www.gps.caltech.edu/~blair/orca/docs/orcallator.html#processes_in_run

_queue
}


And this is my data file "monitoring_ping" (around 300 lines):

ping_avg timestamp
100 1006266960
109 1006267020
102 1006267081
116 1006267141
106 1006267200
114 1006267260
126 1006267320
100 1006267380
100 1006267440
.....


and this is what I get when I run it:

As You can see, everything looks ok, until the line "Creating RRD ". There
is an error in the next line about "unparsable time ...."
html  files are being created, but there are no PNGs. should the PNGs be in
the same dir as html files?

Should I change "date_source" in the group from
date_source             column_name timestamp

to
date_source             ping_avg timestamp

or should I leave it as it is? I tried to change it, but I allways got an
error, so I didn't change it.


I am really sorry because of writing so much, but I have no idea, what
should I do. I don't need (at the moment) any maths in the plot, I just
want
it to draw a graph by using these 300 lines (this is just an example file,
the real file has thousands and thousands of lines).

Thanx a lot one more time and I hope that You can help me.

J.
