Oracle rdbms big tablespace

Hello,

we monitor Oracle Databases with the latest CHECK_MK RAW-Version. Some database have big tablespaces. With the oracle plugin I can only identify them bei this (free):

OK - ONLINE (PERMANENT), Size: 1.52 TB, 1.13% used (1.44 TB of max. 128 TB), Free: 126.56 TB

Actually this server has no so much space available.

Questions:

  1. Is there another way to identify big tablepsaces?
  2. Must I create for every big tablespace one rule to be informed when the tablespace is full with the max size of the avaiable storage?

Regards,
Michael
