Hi

I'm having issues getting this working. I'm running Windows 2003 server.

I downloaded RRDpo.pm from http://oss.oetiker.ch/rrdtool/pub/contrib/
I then renamed to RRDp.pm as this is what it looks like your script is looking for. I then put this file in the C:\strawberry\perl\site\lib folder

I update my path too RRD tool in your script and tried to run it but get this error.


F:\rrd_resize_perl_script>perl resize.pl -g 1205 -f "F:\apache2\htdocs\cacti\rra
\csidub1_traffic_in_1448.rrd" -s 795 -o F:\Temp_rrd\

has anyone seen this before and know how to fix it?

Hi

I have just tried a different RRDp.pm file, found here http://my.fit.edu/~jarias/rrdtool/lib/p ... .8/RRDp.pm

After hashing out the following line
# fcntl RRDreadHand, F_SETFL,O_NONBLOCK|O_NDELAY; #make readhandle NON BLOCKING

and then setting the path in the resize.pl to
my $rrd_binary = "F:/rrdtool/rrdtool";

I dont see any errors but the script just seems to hang and not complete and this is with me just trying to update 1 rrd.

Any ideas?

Cheers

Just worked out how to debug.

This is where it's hanging.

F:\rrd_resize_perl_script>perl resize.pl -g 1205 -f "F:\apache2\htdocs\cacti\rra
\csidub1_traffic_in_1448.rrd" -s 795 -o F:\Temp_rrd
function make_output_dir called, parms: F:\Temp_rrd
function make_output_dir for F:\Temp_rrd returns: File exists
function get_rras called, parms: F:\apache2\htdocs\cacti\rra\csidub1_traffic_in_
1448.rrd 795

How I can use resize to change my regular rrd to "no data lost" template ?
