Hello everyone,

I'm having strange issue, and spend a lot of time troubleshooting this without any success.

Getting error 'error drawing graph' only for some devices only - EX4200 switches, which are located in the remote datacenter. After I started seeing issue, I install another switch here in local datacenter and added it to observium and its working good. Could be the issue in latency - the delay is about 30ms?

discovery and poller scripts run good, the only thing I noticed that for the devices that don't work I in rrd/<device_name>/ files port-###.rrd are missing. The CPU and Memory graphs are working good, only network graphs are having errors.

Thanks,

Roman.
