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 ASM Instances

Starting in version 5.6.5.5, Foglight for Oracle provides a detailed dashboard for monitoring ASM performance. The ASM information is presented only after ASM instances are configured.

The ASM tab lists all ASM instances which have been configured. To access the detailed dashboard for that instance, click the home button.

Figure 3. ASM tab

The ASM dashboard provides information about the ASM cluster/instance, it includes general instance information, Disk groups and disks information, ASM Parameters and ASM Alert log information.

The ASM dashboard has three tabs:

•
Summary — Reviewing Summary Information
•
Parameters — Reviewing Parameter Information
•
Alert log — Reviewing Alert Log Information

Reviewing Summary Information

The summary tab contains information about all the disk groups that are configured for the ASM, as well as the disks that are configured for each ASM disk group. This information includes the version number, status, total storage space, and the number of ASM clients.

The number of ASM clients is clickable and opens a pop-up that shows all the Oracle instances that are using a disk group managed by the ASM instance.

It also has a column named Monitored that gives an indication whether or not that Oracle instance is monitored by Foglight. If the Oracle instance is not monitored by Foglight, it is possible to monitor it immediately by clicking Monitor.

The Disk Groups table provides detailed information about each group. Selecting one or more disk groups will display additional information in the pane below, either in Map or Table View.

Each disk group in the top table or disk in the Map or Table view is clickable and opens a pop-up with additional information.

Figure 4. Dusk Groups view

For disk groups, the pop-up includes the following tabs:

•
General — General Disk group information. For example, name, state number of disks, number of fail groups, allocation unit size.
•
Storage — Disk group storage-related information
•
Performance — Performance-related information
•
I/O Operations
•
Average Service Time
•
Disk Errors
•
Operations — Currently running rebalance operations
•
Alarms — List of alarms associated with this disk group
Figure 5. Disk Group Details - Performance tab

If you select a specific disk in the Map or Table view, the pop-up includes the following tabs:

•
General — General Disk information (e.g. path, failure group, creation date)
•
Storage — Disk storage-related information
•
Performance — Disk performance-related information

Reviewing Parameter Information

The Parameters tab displays a list of all the ASM parameters and their values, as well as some other additional information for each parameter.
