After further investigation, it turns out that nagiosgraph isn't seeing of the output from my check commands.  This information used to go to my service_perfdata_file.

But now that I've upgraded to 3.3.1, I don't appear to be seeing any of my custom commands (ones that don't have perfdata) in that file.  And upon investigating more, if I include perfdata in my custom commands, it sends to that perfdata_file just fine.  but if the performance data isn't there, it doesn't show up in that file.

nagios 3.3.1 does not process empty perfdata macros anymore which causes 
those results not to be put onto the perfdata channel. so all your 
plugins not returning perfdata won't even be put over there where 
nagiosgraph and other addons might calculate their perfdata from the 
output themselves.

i consider it a bug as it breaks compatibility. previous discussions on 
nagios-* mailinglists can be found in the archive. dunno when this will 
get fixed.

i'd suggest downgrading onto 3.2.3 and wait for a properly tested 3.3.x 
release.

kind regards,
