Event monitoring
When a registered event exceeds a specified threshold, an alert
displays on the OEM Console and an email is sent to the administrator.
Alerts have progressively higher severity levels as shown in the
following table.
Alert State Icon description Alert description
Critical Red flag A red flag would indicate a
critical alert.
Warning Yellow flag A warning threshold has been
reached.
Error State Yellow hexagon with
an exclamation point
An error state indicates there
is a problem with the
evaluation of the event
condition, as opposed to a
threshold being met.
Event
Cleared
Green flag The event has been cleared.
Example, when the database
goes down and comes back
up.
Unknown Gray Flag A gray flag represents an
“unknown” state where it is
not possible for the Oracle
Enterprise Manager to
ascertain the event status
because the node is
unreachable or the Intelligent
Agent is not available.
