Information
The ESXi host must not enable log filtering. You can create log filters to reduce the number of repetitive entries, and to deny specific log events entirely.
Solution
$ESXcli = Get-EsxCli -VMHost $ESXi -V2
$arguments = $esxcli.system.syslog.config.logfilter.set.CreateArgs()
$arguments.logfilteringenabled = $false
$ESXcli.system.syslog.config.logfilter.set.invoke($arguments)
