When the vSphere Client is connected to vCenter Server, you can select hosts from which to download system logs.

To save diagnostic data for ESX/ESXi hosts and vCenter Server, the vSphere Client must be connected to the vCenter Server system. If you are connected directly to an ESX/ESXi host, you can save diagnostic data only for that specific ESX/ESXi host.

Required privileges:

  • To view diagnostic data: Read-Only User
  • To manage diagnostic data: Global.Licenses


  1. Select File > Export > Export System Logs.
  2. If you are connected to vCenter Server, select the object for which you want to export data.
    Selecting an object selects all of its child objects.
  3. If you are connected to vCenter Server, select Include information from vCenter Server and vSphere Client to download vCenter Server and vSphere Client logs as well as host logs.
  4. Click Browse, and specify the location to which to save the log files.

    The host or vCenter Server generates .zip bundles containing the log files. The Recent Tasks panel shows a task called “Generate diagnostic bundles” in progress.

    The Downloading Log Bundles dialog box appears when the Generating Diagnostic Bundle task is finished. The download status of each bundle appears in the dialog box.

    Some network errors can cause download failures. When you select an individual download in the upper part of the dialog box, any the error message for that operation appears in the lower portion of the dialog box, below the name and location of the log bundle file.

  5. If the download fails, click Retry to attempt to download the generated bundles again.


Diagnostic bundles containing log files for the specified objects are downloaded to the location specified.
