This article provides steps to collect diagnostic information for ESX/ESXi hosts and the vCenter Server using the vSphere Web Client.

VMware Technical Support routinely requests diagnostic information from you when a support request is handled. This diagnostic information contains product specific logs, configuration files, and data appropriate to the situation. The information is gathered using a specific script or tool for each product and can include a host support bundle from the ESXi host and vCenter Server support bundle. Data collected in a host support bundle may be considered sensitive. Additionally, as of vSphere 6.5, support bundles can include encrypted information from an ESXi host. For more information on support bundles, see Data collected when gathering diagnostic information from vSphere products (2147388).

Note: For more information, see the vSphere Monitoring and Performance Guide. This guide contains definitive information. If there is a discrepancy between the guide and the article, assume the guide is correct.


When the vSphere Web Client is connected to the vCenter Server system, you can select hosts from which to generate and download system log files and the option to include vCenter Server and vSphere Web client logs.

Note: This functionality was added in the vSphere Web Client 5.1. It is not available in previous versions.
To collect ESX/ESXi and vCenter Server diagnostic data:
  1. Start the vSphere Web Client and log in to the vCenter Server system.
  2. Under Inventory Lists, select vCenter Servers.
  3. Click the vCenter Server that contains the ESX/ESXi hosts from which you want to export logs.
  4. Click the Monitor tab and click System Logs.
  5. Click Export System Logs.
  6. Select the ESX/ESXi hosts from which you want to export logs.
  7. Select the Include vCenter Server and vSphere Web Client logs option. This step is optional.
  8. Click Next.
  9. Select the system logs that are to be exported.
  10. Select Gather performance data to include performance data information in the log files.

    Note: You can update the duration and interval time between which you want to collect the data.

  11. Click Next.
  12. Click Generate Log Bundle. The Download Log Bundles dialog appears when the Generating Diagnostic Bundle task completes.
  13. Click Download Log Bundle to save it to your local computer.

    Note: The host or vCenter Server generates .zip bundles containing the log files. The Recent Tasks panel shows the Generate diagnostic bundles task in progress.

  14. After the download completes, click Finish or generate another log bundle.
Note: You can use the events log to troubleshoot issues, particularly when trying to determine a timestamp.

To export the events log:
  1. Select an inventory object.
  2. Click the Monitor tab, and click Events.
  3. Click the Export icon.
  4. In the Export Events window, specify what types of event information you want to export.
  5. Click Generate CSV Report, and click Save.
  6. Specify a file name and location and save the file.

Additional Information

Note: You can also you use the Log Browser feature in the vSphere Web Client to view, search, and export one or more vCenter Server or ESXi log files. For more information, see Using the Log Browser to view, search, and export Logs for troubleshooting (2032888).
