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.
Make sure you're running the latest version, there were some issues with a change earlier this week.
JunOS is a special little butterfly and needs special attention sometimes...
Latency won't really have that effect, the only thing that is likely to is failing to receive data from the switch, which may be fixed in the latest revisions.
