Reviewing the Alert Log

By default, the Alert Log panel displays all of the alert log messages.

To display messages under a pre-defined name, category and severity, create or edit patterns for these messages in the Match List, which is found in the Alert Log view in the Databases Administration dashboard, and add the corresponding regular expressions to this list. To prevent messages from being displayed on the Alert Log panel, add these messages to the Ignore List.

* 
IMPORTANT: Only messages that are explicitly defined in the Ignore List will not be displayed. Messages that were not added to either the Match or Ignore lists appear with the name Other, the type of Oracle alert messages, and the severity Information. Therefore, ensure that messages that do not need to be displayed are added to the Ignore List.

The Alert Log panel comprises the panes described in the following topics:

•
Alert Log Messages Chart
•
Alert Log Messages Table
Alert Log Messages Chart

The Alert Log Messages chart provides a graphic, color-coded representation of the various alert log messages, broken down by their severity level, as described below.

•
Informational — displayed on the screen, but does not invoke alarms
•
Warning
•
Critical
•
Fatal

The severity assigned for each alert, as well as the minimal severity level (Warning or higher) for which alarms are to be invoked as a result of the alert, are defined using the Alert Log view in the Databases Administration dashboard, accessible from the Agent Settings button.

Alert Log Messages Table

The Alert Log Messages table provides the following details about each alert log:

•
Timestamp — the exact time and date when the alert log message was created
•
Severity — can have one of the values listed below
•
Informational
•
Warning
•
Critical
•
Fatal
•
Message — the title of the Oracle error message
•
Dump File — this field is populated by a link only if the error message also refers to a dump file. When the link is clicked, the Dump File popup appears, displaying the first 100 lines of the dump file contents.
•
Name — the alert log name
•
Type — the alert log type, such as Oracle errors or Oracle alert messages
* 
NOTE: Both Name and Type refer to the parameters defined using the Alert Log view in the Databases Administration dashboard.

Reviewing Monitored Data Guard Environments

Starting in version 5.7.5.50, Foglight for Oracle provides a detailed dashboard for monitoring Data Guard environments. The Data Guard environment information is presented only after Data Guard environments are configured. The Data Guard tab lists all Data Guard environments which have been configured.

To access the detailed dashboard for that Data Guard environment, click the name of that Data Guard environment under the Name column.
