Using the ETSM applications to monitor tablespaces

The ORACLE_ETSM application supports the monitoring of both autoextensible and non-autoextensible tablespaces in the database except for those that are excluded from monitoring. ORACLE_ETSM automatically sorts tablespaces into logical application containers.

The ORACLE_ETSM application discovers and monitors the percent used (PctUsed) and space left (SpaceLeft) for all tablespaces, except those that are excluded from monitoring. It places the tablespaces in ETSM_<tablespaceType> applications according to types. For more information, see Defining tablespace types.

For autoextensible tablespaces, the SpaceLeft and PctUsed parameters consider the maximum size of a datafile and actual space available on the disk.

The ORACLE_ETSM uses the following approaches to monitor the ETSM (ORACLE_ETSM) application:


When monitoring tablespaces with data files that reside in the ASM Storage, make sure the following is true::

export ORACLE_SID=xxxx

export ORACLE_HOME=/xx/xxxx/xxxxx/xxxxxx


sqlplus mon_account/password

SQL>select count(*) from v$asm_diskgroup_stat;

The returned value must not equal a 0 value.

ORACLE_ETSM correctly monitors the tablespaces when the following Oracle objects are used:

  • dba_free_space
  • dba_data_files
  • dba_tablespace_usage_metrics
  • dba_tablespaces
  • dba_temp_files
  • v$sort_segment
  • v$temp_extent_pool
  • v$tempstat
  • v$tempfile
  • v$tablespace
  • v$filestat
