Health indicators
The health monitor uses health indicators to evaluate the health of specific
aspects of database manager performance or database performance. A health indicator measures the
health of some aspect of a particular class of database objects, such as table
spaces.
Criteria are applied to the measurement to determine healthiness.
The criteria applied depends on the type of health indicator.
Important: The health monitor, health indicators, and related components
have been discontinued with the exception of the HEALTH_MON database manager
configuration parameter, the GET HEALTH SNAPSHOT command and the HADR health
indicators (
db.hadr_op_status and db.hadr_delay), which remain
deprecated.Health monitor returns State-based indicators. State-based indicators are measurements that represent a finite set of two or more distinct states of an object that defines whether the database object or resource is operating normally. One of the states is normal and all others are considered non-normal. State-based health indicators have two valid states: Normal, Attention.
Health indicators exist at the database level. You can access health indicators through the CLP.
