Depending on the configuration of the DB2 instance, the following actions can
occur when the health monitor generates an alert:
v An entry is written in the administration notification log, which you can read
from the Journal.
v A script or task is executed.
v An e-mail or pager message is sent to the contacts that you specify for this
instance.
The following are some of the key tasks that you can perform with the Health
Center:
v View the status of the database environment. Beside each object in the
navigation tree, an icon indicates the most severe alert for the object (or for any
objects contained by that object). For example, a green diamond icon beside an
instance means that the instance and the databases contained in the instance do
not have any alerts.
v View the alerts for an instance or a database. When you select an object in the
navigation tree, the alerts for that object are shown in the pane to the right.
v View detailed information about an alert, and recommended actions. When you
double-click an alert, a notebook appears. The first page shows the details for
the alert. The second page shows any recommended actions.
v Configure the health monitor settings for a specific object, and the default
settings for an object type or for all objects within an instance.
v Select which contacts will be notified of alerts with an e-mail or pager message.
v Review the history of alerts for an instance.
You
can use the toggle buttons at the top of the navigation bar to filter the alerts
according to their severity:
v
Displays only alarms (the most severe type of alert)
v
Displays alarms and warnings
v
Displays alarms, warnings, and attentions
v

The Web version of the Health Center includes a subset of these features.
