ResUsageSldv vs ResUsageSvdsk


ResUsageSldv vs ResUsageSvdsk

This is the extract from Teradata documentation for the two tables:

The ResUsageSldv table:
Contains resource usage information for system-wide, logical device information. Statistics from this table are collected from the SCSI bus level.

The ResUsageSvdsk table:
• Provides AMP-level vdisk logical device statistics.
• Includes resource usage logs on cylinder allocation, migration, and I/O statistics.
If table logging is enabled on ResUsageSvdsk, the data is written once for each AMP Vproc log period.

Where can I get the log of disk usage that lies in between SLDV and SVDSK?

SLDV data can be SCSI or PDISK level information. See the xctl / ctl utility. There's nothing "in between" AMP and PDISK level.
