    Storage Performance Metrics?

      I have noticed when I check out the /proc filesystem, there are a few parameters that show up with respect to disk activity.  Unfortinately, they seem to be vmware-specific and there is nothing in the documentation about them.  I have some thoughts, but I'd love it if someone in the know could help me out:

       

       

      in /proc/vmware/scsi/vmhbaX :

       

       

      paeCmds  paeCopies  splitCmds  splitCopies

       

       

       

      I have noticed when people post outputs when they are having storage issues normally have a high number of bus resets AND high values in these fields. 

       

       

      When I encounter a host without issues, these numbers are generally zero.

       

       

      Anyone??
