This article provides the default location of the most common ESX log files.


Logs on an ESX host can be reviewed from:

ESX 3.x and 4.x Host Log Files

  • /var/log/vmkernel – Core VMkernel logs, including device discovery, storage and networking device and driver events, and virtual machine startup.

  • /var/log/vmkwarning – Summary of Warning and Alert log messages excerpted from the VMkernel logs.

  • /var/log/vmksummary – Summary of ESX host startup and shutdown, and an hourly heartbeat with uptime, number of virtual machines running, and service console resource consumption.

  • /var/log/messages – Messages from the Service Console Linux kernel, including service startup and shutdown.

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

  • /var/log/boot-logs/sysboot.log Early VMkernel startup, module loading, and host initialization.

  • /var/log/vmkiscsid.log Software iSCSI Client logs.

Logs from vCenter Server Components on ESX 3.x and 4.x

When an ESX host is managed by vCenter Server or VirtualCenter Server, two components are installed, each with its own logs:

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

  • VMware High Availability logs:
    • If managed by vCenter Server 5.0 or later – /var/log/vmware/fdm/*
    • If managed by vCenter Server 4.1 or earlier – /var/log/vmware/aam/*
