Collecting VMware Diagnostic Information

When you open a support request, VMware requests diagnostic information. In order to simplify gathering this diagnostic information, we have created new Knowledge base articles. We wrote these articles to help minimize the amount of time it takes to get your issues resolved.

The main article in this series is Collecting diagnostic information for VMware products (1008524). This article contains links to instructions for each VMware product. We have been very careful to ensure each article identifies the procedure for only one  product. This will help to ensure all the information in these articles is accurate, and never gives you information that has become outdated (so update your bookmarks!).

In addition to these new product specific instructions, each article contains links to instructions for opening a support request and uploading the information to VMware. By ensuring consistent access to this information, we make sure you don’t have to look far to find what you need when you get support from us.
