Guidelines

Announcement Support for this product will end on December 22, 2025. To monitor Oracle databases, we recommend that you use PATROL for Oracle Enterprise Database.

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:

Note

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
export PATH=$PATH:$ORACLE_HOME/bin
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
