NIC Event/Error Logging for ESXi 5.0 and 5.1
Retrieving ESXi Server NIC Error Log Codes
For ESXi Server systems, the NIC driver generates error codes to the
/var/log/vmkernel log file. The vmkernel log file is an ASCII text file that can be
viewed and searched with a text editor such as vim. The vmkernel log file is
automatically rotated as it gets larger, and the rotated log files are named vmkernel.x,
where x is an integer.
To search the log file for error messages, at the command prompt, type:
#cd /var/log
#less vmkernel
For example, you might see the following message:
Sep 9 19:48:04 esx-server vmkernel: WARNING: Found a OneConnect card
in Gen 1 x8 PCI-e slot. Should be in Gen 2, x8 slot for best
performance.
