Hi all, Thought I would share my success... A coworker threw on Data::Dumper on the script and we output the unix second that were being passed off to the RRDs.pm library. Interestingly... the last update time reported from the RRD file looks right, the current time is right, but the RRDs.pm fetch function reports back a start time in the future when a computed timestamp of ($lastupdatetime - 120) is requested... obviously rrd is not able to look into the future, so the results are undefined.
lastupdatetime=1330642128 ; lasttimestamp=1330642221 ; $start = 1330642200 ; Until I get a chance to dig into the RRDs.pm, here is a quick fix for the "check_smokeping.pl"... @@80 -- my ($start,$step,$ds_names,$data) = RRDs::fetch($rrd_file,"AVERAGE","-s",$lastupdatetime - 120,"-e","now"); ++ my ($start,$step,$ds_names,$data) = RRDs::fetch($rrd_file,"AVERAGE","-s","-2m","-e","now"); Hope this helps someone...

The export/import dance is needed because the binary format is different, so maybe the version of the RRD library that the check script is using, is still expecting the old format? just a guess. /Lars 2012/3/1 Peter Brunnengräber <[email protected]>: > Hello all, > I recently upgraded from a 32-bit to 64-bit debian and I did the export and > import of my RRD files.
