Purpose

This article describes a method to capture logs from ESX/ESXi hosts via a serial port using the third-party software PuTTY.

Note: VMware does not endorse or recommend any particular third party utility.

This article assumes:

The ESX/ESXi host is properly configured to send logs to the serial port. For more information, see Enabling serial-line logging for an ESX and ESXi host (1003900).

PuTTY is installed and working on a Windows computer.

The ESX/ESXi host's serial communications port is connected to the computer running PuTTY using a serial null-modem cable.

Resolution

PuTTY can be configured to capture log text arriving on a serial port and to record it to files on the disk.

To configure PuTTY to capture logs:

Download PuTTY from http://www.chiark.greenend.org.uk/~sgtatham/putty/.

Note: The preceding link was correct as of February 25, 2011. If you find the link is broken, provide feedback and a VMware employee will update the link.

Open PuTTY.

Select the Connection Type Serial.

Enter COM1 or COM2 in the Serial Line field, depending on which serial port is connected.

Enter a serial baud rate to match the ESX/ESXi host. By default, ESX/ESXi use a serial baud rate of 115200.

Under Session in the left pane, select Logging.

Under Session logging, select the All session output option.

Specify a file name to record to the disk. Putty provides advanced options for automatically creating filenames. For more information on using the log file name options, see the PuTTY documentation.

Note: The preceding link was correct as of February 25, 2011. If you find the link is broken, provide feedback and a VMware employee will update the link.

Click Open. PuTTY opens a terminal window. The logs received on the serial port are displayed on the screen and are written to the log file configured in Step 8.

Note: To stop capturing logs, close the PuTTY window.
