Monitor blobspace usage with oncheck -pe

The oncheck -pe command provides information about blobspace usage:
  • Names of the tables that store TEXT and BYTE data, by chunk
  • Number of disk pages (not blobpages) used, by table
  • Number of free disk pages remaining, by chunk
  • Number of overhead pages used, by chunk

The following example shows sample oncheck -pe output.
