ESXi Logs in DCUI Console


In DCUI Console, under system logs you will find 6 logs as listed below.

  • Syslog.log
  • Vmkernal.log
  • Config (sysboot.log)
  • Management Agent (hostd.log)
  • Virutalcenter agent (vpxa.log)
  • Vmware esxi observation log (vobd)


Syslog.log holds logs for Management service initialization, watchdogs, scheduled tasks and DCUI use.

We can view this log at https://<ESXi FQDN or IP>/host/syslog.log


This log includes Core VMkernel logs, including device discovery, storage and networking device and driver events, and virtual machine startup.

The VMkernel provides basic operating system services needed to support virtualization: hardware abstraction, hardware drivers, scheduler, memory allocator, filesystem (vmfs), and virtual machine monitor (vmm).

We can view this log at https://<ESXi FQDN or IP>/host/vmkernel.log

Config (sysboot.log)

This log includes VMkernel startup and module loading.

We can view this log at https://<ESXi FQDN or IP>/host/sysboot.log

Management Agent (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.

It knows about all the VMs that are registered on that host, the luns/vmfs volumes visible by the host, what the VMs are doing, etc.

We can view this log at https://<ESXi FQDN or IP>/host/hostd.log

Virtualcenter agent (vpxa.log)

vCenter Server vpxa agent logs, including communication with vCenter Server and the Host Management hostd agent

Vpxa runs if you are connected to a vCenter server. Standalone esxi will not use it. It acts as an intermediary between vpxd on vCenter server and hostd on ESXi.

We can view this log at https://<ESXi FQDN or IP>/host/vpxa.log

Vmware esxi observation log (vobd)

VMkernel Observation events, similar to vob.component.event. Also contains logs for failed login attempts.

We can view thi log at https://<ESXi FQDN or IP>/host/vobd.log
