Oreon doesn't graph only SOME graphs

[james.t]

Hi guys i have a problem with the grapher on oreon.
I checked the root disk usage graph in perfparse and it's showing up fine but i'm getting a broken image link in oreon with the following message:

ERROR: opening '/usr/local/oreon/filesGeneration/graphs/simpleRenderer/rrdDB/xxx_Root-Partition.rrd': No such file or directory

also in my apache2 log i get the following:

ERROR: Invalid DS name
ERROR: Invalid DS name
ERROR: Invalid DS name
ERROR: Invalid DS name
ERROR: Invalid DS name
ERROR: Invalid DS name

The graphs for load usage are showing up fine in oreon along with some other graphs.

I dunno what could be causing this. Any help?

does the file actually exists ?

maybe a naming issue > try renaming the service check with a shorter name or without special characters.

Yeah well rrdtool is suppose to create that file. I tried touching the file and giving my apache user access to it but whenever i try to make the graph it deletes that file and tries to make a new one.
As for the check services it's just called check_root
I think that's pretty short considering i have ones longer than that.
I'm pretty stumped by it
