The vma-support script enables you to collect various system configuration information and other logs. The script generates the information as a log bundle and appends it to the vmware.log file on the ESX host on which vMA is deployed. However, when vMA support stream is redirected to ESX, it is saved in vmware.log as a plain text encoded by base64, and is captured by vma-support by default, but there is no way to extract and decode the stream.

Copy the vmware.log file to the vMA appliance to analyze the log bundle.


  1. Run vmware-xferlogs dec vmware.log command from vMA. The decoded log files are displayed. For example:
    vi-admin@wdc-eeapps-dhcp162:~> vmware-xferlogs dec vmware.log
    reading file vm-2013-07-08.14827.tgz to 0_1373516751.log
    reading file vm-2013-07-09.1451.tgz to 1_1373516751.log

  2. Run "tar -xf <filename>" to extract the log files. For example:
    vi-admin@wdc-eeapps-dhcp162:~> tar -xf 0_1373516751.log
    vi-admin@wdc-eeapps-dhcp162:~> tar -xf 1_1373516751.log


vm-support.1451 and vm-support.14827 folders are created in the current folder, which consists of original log files in a readable format.
