Hi Chip,

Your filesystem was full or some other corruption has occured.

do : 

rm /opt/observium/rrd/router.local.com/port-62.rrd

And it should correct itself.

This happens when an rrd file is created incorrectly, usually because the disk is full and can't be read back later. Make sure your disk isn't full, and if it's an SSD, beware you may need to replace it!

Hi All,

I'm seeing "error drawing graph" on several of our Cisco ASR's interfaces, so I'm hoping someone coupe point me in the right direction.  I'm running Centos 6.6 with the latest rrdtool rrdtool-1.3.8-7.el6-x86_64 and CE version 0.15.6.6430.  I've removed the specific graph rrd file then run the following two commands for debugging purposes.  php ./discovery.php -d -h router.local.com php ./poller.php -d -h router.local.com.   The file is 0 bytes for some reason.  Oddly enough two of the three interfaces issues are with BDI interfaces. The weird part is there is one BDI interface on each box that is displaying correctly.  Let me know if you any anything else to assist in troubleshooting. 

Thanks,
Chip
