Some Cacti Graphs not graphing after server restart

[childebrecht]

Hello,
I am running Cacti on a centos server. Last week I was updating some OIDs for some of my data templates and had to restart the server. Since then I random existing graphs that have been graphing for years now not graphing any more. It is giving an SNMP error. These were working before system restart. It is now acting like Cacti cannot reach some of the servers.

12/14/2018 11:20:23 AM - CMDPHP: Poller[0] WARNING: SNMP GetNext Timeout for Host:'10.80.10.10', and OID:'.1.3'

Has anyone else come across this issue after a system reboot?

Thank you,
Chris

I would check that you have all the routing entries that you expect (netstat -rn) as it may be someone manually put a route in but didn't make it permanent via a configuration file.

Thank you for that information. That ended up being the issue. Everything is working now.
