Configure VMware ESXi syslog forwarding using VMware PowerCLI

You can configure syslog setting across multiple VMware ESXi hosts simultaneously using VMware PowerCLI. This method is recommended for automation.

These actions are required:

  • Ensure VMware PowerCLI is installed and connected to the target VMware vCenter environment.

These resources are required:

  • An activated and dedicated Virtual Log Collector (vLC)
    Note: Due to the high event volume observed during Early Access (EA) customer deployments, this integration requires a dedicated vLC to help maintain platform stability and performance and to reduce the risk of service disruptions caused by excessive log volume.
  • Administrator access to VMware ESXi environments through the vSphere Client or ESXi Host Client
  • Network connectivity between VMware systems and the vLC

Configure syslog forwarding

  1. Run this command to set the syslog destination:
    CODE 
    Get-VMHost | Get-AdvancedSetting -Name Syslog.global.logHost | Set-AdvancedSetting -Value "udp://<vlc_ip>:514" -Confirm:$false

    Where vlc_ip is the IP address of your vLC.

  2. Run this command to set the logging level:
    CODE 
    Get-VMHost | Get-AdvancedSetting -Name Syslog.global.logLevel | Set-AdvancedSetting -Value "info" -Confirm:$false
