The RRDtool error is because the files are 0 bytes. Is your rrd partition/disk/ramdisk full?
You'll have to remove the 0-byte files, because if the file exists, Observium will not recreate it, but the files in place now are corrupt as far as RRDtool is concerned, so no new data will be showing up.

Hi all,
I have a problem with the "Device Traffic"-Graph in Observium (r5581) since I inserted two modules 22Ports (J9536A) into the backplane of a HP 5406zl. It is not plotted anymore as you can see in the attached device-traffic.png. The Error-Message from RRDTool is: RRDTool Output: ERROR: mmaping file '/srv/observium/rrd/x-fra01.tfhbo.de/port-97.rrd': Invalid argument.
The file port-97.rrd is empty, but observium added the Ports yesterday. Eventlog: 23-06-2014 18:37:13 Inventory Inventory added: class port, name Port F22, index 217 .... and so on.
Maybe it is just a side-effect: All of the other new Ports, are not plotted, too. Any suggestions? (Except buying a "real" switch... ;-))
