We have recently upgraded our test environment from VMware ESXi 5.5 to 6.0. After the upgrade, we are seeing an issue where errors are getting reported on the vmk1 - vmk5 (VMkernel) ports that are connected to distributed switches for SAN access. However, there are no errors (none reported in vSphere nor the SAN). It seems to be a SNMP issue, possibly.
We have a near identical production environment that is still running VMware ESXI 5.5, and the similar ESXi hosts are not showing these errors in Observium. This is a completely separate network, with a different Observium server, however both are running similar installs, and patched to the latest Professional version. We have verified using normal snmp commands that everything seems to be working as expected. We have deleted and re-added the ESXi hosts. Issue remains, but only on the vmk ports that are connected to distributed switches. The normal vmnic (vSwitch for management VLAN) show no errors.
I've checked the mailing list and Googled this issue for a bit, but not finding anything similar to our issue. Anybody else running Observium with ESXi 6.0 and notice an issue with false Error reports on vmk ports? Any suggestions on what else to try? We have compared everything in the working production environment to the broken test environment, and the only thing we can come up with is that it is an issue with ESXi 6.0 and how it is responding to the Observium SNMP requests. Any guidance or direction would be appreciated.
