You can review ESXi 5.0 host log files:

ESXi 5.0 Host Log Files

Logs for an ESXi 5.0 host are grouped according to the source component:

  • /var/log/auth.log: ESXi Shell authentication success and failure.

  • /var/log/dhclient.log: DHCP client service, including discovery, address lease requests and renewals.

  • /var/log/esxupdate.log: ESXi patch and update installation logs.

  • /var/log/hostd.log: Host management service logs, including virtual machine and host Task and Events, communication with the vSphere Client and vCenter Server vpxa agent, and SDK connections.

  • /var/log/shell.log: ESXi Shell usage logs, including enable/disable and every command entered. For more information, see the Managing vSphere with Command-Line Interfaces section of the vSphere 5 Command Line documentation and Auditing ESXi Shell logins and commands in ESXi 5.x (2004810).
  • /var/log/sysboot.log: Early VMkernel startup and module loading.

  • /var/log/boot.gz : A compressed file that contains boot log information and can be read using zcat /var/log/boot.gz|more .

  • /var/log/syslog.log: Management service initialization, watchdogs, scheduled tasks and DCUI use.

  • /var/log/usb.log: USB device arbitration events, such as discovery and pass-through to virtual machines.

  • /var/log/vobd.log: VMkernel Observation events, similar to vob.component.event.

Note: For clarification VOB and the corresponding service VOBD propagates kernel level errors to third-party applications. VOBD is a daemon that VMware and third-party applications use for monitoring and troubleshooting.
  • /var/log/vmkernel.log: Core VMkernel logs, including device discovery, storage and networking device and driver events, and virtual machine startup.

  • /var/log/vmkwarning.log: A summary of Warning and Alert log messages excerpted from the VMkernel logs.

  • /var/log/vmksummary.log: A summary of ESXi host startup and shutdown, and an hourly heartbeat with uptime, number of virtual machines running, and service resource consumption. For more information, see Format of the ESXi 5.0 vmksummary log file (2004566).

Note: For information on sending logs to another location such as a datastore or remote syslog server, see   Configuring syslog on ESXi 5.0 (2003322)

Logs from vCenter Server Components on ESXi 5.0

When an ESXi 5.0 host is managed by vCenter Server 5.0, two components are installed, each with its own logs:

  • /var/log/vpxa.log: vCenter Server vpxa agent logs, including communication with vCenter Server and the Host Management hostd agent.

  • /var/log/fdm.log: vSphere High Availability logs, produced by the fdm service. For more information, see the vSphere HA Security section of the vSphere 5.0 Availability Guide.

Note: If persistent scratch space is configured, many of these logs are located on the scratch volume and the /var/log/ directory contains symlinks to the persistent storage location. Rotated logs are compressed at the persistent location and/or at /var/run/log/. For more information, see Creating a persistent scratch location for ESXi (1033696).
