Monitoring by exception

The ETSM application uses the exception-based approach by default. With this approach, all tablespaces are initially monitored for percent used (PctUsed) and space left (SpaceLeft) parameters only. When the container-level parameter thresholds are crossed, additional monitoring for the tablespaces is initiated.

When a tablespace exceeds the thresholds set for PctUsed and SpaceLeft, the ETSM application performs the following actions:

• creates an ETSM_TBSP_INSTANCE for that tablespace
• places that ETSM_TBSP_INSTANCE under the appropriate ETSM_ tablespaceType application
• monitors that ETSM_TBSP_INSTANCE with the same set of parameters used in the original tablespace monitoring (except for the AutoExtended parameter)

For information about the PctUsed and SpaceLeft parameters, see ETSM parameters.
