Uploading diagnostic information for VMware (KB: 1008525)


VMware Technical Support uses a set of diagnostic information obtained from our products when addressing a support request. This diagnostic information contains product specific logs and configuration files from the host on which the product is run. This information is gathered using a specific script or tool within the product. For more information on obtaining the diagnostic information, see Collecting diagnostic information for VMware products (1008524).
After you obtain the necessary information, you must upload it to VMware.

This article provides instructions for uploading diagnostic information to VMware support.

Note: Uploading diagnostic information is the same as uploading log files.


Upload options

To address a Support Request, VMware technical support requests diagnostic information from the VMware products. You can send diagnostic information to VMware support technicians using one of these options:
  • If there are several log files, VMware recommends that you create a single ZIP, TAR or TGZ file and upload that. The single file makes the process more efficient.
  • If your files are larger than 2 GB, you must upload using the vCenter Support Assistant 5.1.1 or by using the FTP portal or the Secure FTP portal.

Uploading via vCenter Support Assistant 5.5

VMware vCenter Support Assistant is a free plug-in for VMware vCenter Server that creates and manages Support Requests and generates and uploads logs. It can also automatically collect diagnostic data about your environment and alert you to problems in your environment before they cause outages.
VMware vCenter Support Assistant 5.5 uses both FTP and best-effort HTTPS to transmit files to VMware. The transmission process is transparent to the user, and defaults to HTTPS for all uploads.

Uploading by Email

Files can be attached to an email to your support representative. This method is effective if you have already received an email from your representative and can reply. If you choose this method, do not modify the subject line of the email to ensure the message is associated with your support request properly.

Note: You can send files up to 10 MB in size via email. Only use email to send screen shots and individual log files. Certain compressed file formats are filtered for security reasons.
