Health indicators (HIs) determine and display the health of specified aspects of a monitored CI. An HI is an event-driven monitor that uses one value to represent the normal state of the CI, for example, System:Running. One or more additional values are used to represent any abnormal states, such as System:Stopped. In this way, health indicators are used to show if a hardware resource is available and responding.
Health indicators can also display the state of a software application. For example, the possible states of a database server could be specified as: Available, Starting or Stopping. Health indicators can also be used to show the usage of a software application, for example, whether the load is Normal, High, or Max. Exceeded.
Only events that provide CI state information can set an HI. Health indicators are assigned to a specific configuration item type. OMi sets indicators automatically using event attributes or indicator mapping rules.
Although HIs can affect the status of a KPI, this is not always the case. For example, the HI Number of open sessions:2 contains information about an application, but it does not reflect what the CI's normal state is or if the number of open sessions is good or bad.

Mapping Rules
Mapping rules can be used to match attributes of incoming events to defined health indicator values, such as Low or High, for a given configuration type. For example, you can define an HI to display the health of the CPU load on UNIX systems (CI type: Infrastructure Element > Node > Computer > Unix). When an event reporting Low or High CPU load is received, the appropriate health indicator value is set.

How to Reset Health Indicators
Resetting an HI is a way of returning an object's severity status to a defined default value such as Normal.
Note Resetting an HI is not usually necessary and should be performed in exceptional circumstances only, for example, when OMi does not reset it automatically.
