Finding ESXi hosts with IP conflicts

I recently had a client with some ESXi hosts having intermittent issues with NFS storage. After checking vmkernel.log (and confirming via vodb.log) I found that these hosts were reporting IP conflict errors. Someone bought extra drinks that night!

The following PowerCLI script will help check /var/log/vmkernel.log on each ESXi host in a cluster.
