Modifying Alarm Settings

You can customize how the alarms generated by the default Foglight for Oracle rules are triggered and displayed in the Alarm view’s Settings tab. All changes to alarm settings apply to the selected agents, with the exception of thresholds, which can be customized by agent.

The Alarms list controls the contents displayed to the right and the tasks that are available.

All Alarms – Displays all rules with configured alarms and indicates whether alarms are enabled. In this view, you can enable or disable alarms for all the rules at once. You can also set email notifications and define mail server settings.
Category of rules – Displays a set of related rules with configured alarms. In this view, you can enable or disable alarms and also set email notifications for the category of rules.
Rule name – Displays the alarm status for the selected rule. If the rule has multiple severity levels, displays the threshold configured for each severity level. In this view, you can enable or disable the alarm, edit the alarm text, and edit severity levels and their thresholds. You can also set email notifications for the alarm.

You can complete the following tasks:

Your changes are saved separately and applied over the default rules. This protects you from software upgrades that may change the underlying default rules.

You can override the global alarm sensitivity level setting for the selected agents. You can enable or disable alarms for all rules, a category of rules, or an individual rule.

You can and should modify the thresholds associated with alarms to better suit your environment. If you find that alarms are firing for conditions that you consider to be acceptable, you can change the threshold values that trigger the alarm. You can also enable or disable severity levels to better suit your environment.

When a rule has severity levels, a Threshold section appears in the Alarm Settings tab showing the severity levels and bounds by agent. Many rules, such as Baseline rules, do not have severity levels and thresholds.

When editing thresholds, ensure that the new values make sense in context with the other threshold values. For most metrics, threshold values are set so that Warning < Critical < Fatal. However, in metrics where normal performance has a higher value, such as DBO - SGA Library Cache, the threshold values are reversed: Warning > Critical > Fatal.

Configuring Email Notifications

We recommend that you set email notifications for the alarms you are most interested in tracking closely. For example, you may want to be notified by email of any Critical or Fatal situation. Or you may want to be informed whenever a key metric, such as CPU usage, is no longer operating within acceptable boundaries.

You can set up email notifications that are generated when an alarm fires and/or on a defined schedule, as described in the following topics:

You need to define the global mail server variables (connection details) to be used for sending email notifications. The setting of the email should be configured in Foglight Administration > Email configuration.

You can define a default email address to be used by every new agent created in the future, by selecting the Default email button when configuring email notification.

The Email addresses entered are applied to all monitored agents not only for the agents that were selected to enter the Alarm administration.

You can enable or disable email notifications for all alarms, a category of alarms, or a selected rule. Email notifications are sent only if all the following conditions are met:

All alarms

Click All Alarms. In the Alarms Settings tab, click the Define Email Settings button. Select either Enabled or Disabled from the Alarms notification status list. Click Set.

Category of rules

Click a category. Click the Define Email Settings button. Select either Enabled or Disabled from the Alarms notification status list. Click Set.

Selected rule

Click a rule. In the Alarms Settings tab, click the Define Email Settings tab. Click the link that displays the alarm notification status. Select Enabled or Disabled and click Set.

4
Click Save changes.

You control who receives email messages, the subject line, and some text in the body of the email. The body of the email always contains information about the alarm. This information is not editable. You can also control whether an email is sent based on severity levels. You can set different distribution lists for different rules and different severity levels, or set the same notification policy for all rules.

All alarms

Click All Alarms. In the Alarms Settings tab, click the Define Email Settings button. Continue to Step 4.

Category of rules

Click a category. Click the Define Email Settings button. Continue to Step 4.

Selected rule

Click a rule. Click the Define Email Settings tab.

If you selected All Alarms or a category, in the Email Notification Settings dialog box, do one of the following:
To change the severity levels that warrant an email notification, from the Messages will be enabled for severities box, select the desired levels of severity.
To configure the same email recipients and message for all severity levels, click Configure mail recipients for all Severities and then click All severities.
To configure different email recipients and messages for each of the severity levels, click Configure mail recipients for the following options and then click a severity level.
To — Type the addresses of the people who need to take action when this alarm triggers.
CC — Type the addresses of the people who want to be notified when the alarm triggers.
Subject — Optional. Edit the text of the subject line to better suit your environment. Avoid editing the variables, which are identified with the @ symbol.
Body PrefixOptional. Add text that should appear above the alarm information in the body of the email.

You can create registry variables that contain one or more email addresses and (optionally) their scheduled notifications, and use these registry variables when defining email notifications. This procedure describes how to create a registry value. For schedules, see Defining scheduled email notifications.

On the navigation panel, under Dashboards, click Administration > Rules & Notifications > Manage Registry Variables.
2
Click Add.

Click Finish.

If someone wants to receive an email about an alarm on a regular basis, such as once a day, you use a registry variable schedule to set up the notification.

1
If you are continuing from Defining variables to contain email recipients, the registry variable is already open for editing in the Edit Registry Variable dashboard.
TIP: To edit a different variable, navigate to the Administration > Rules & Notifications > Manage Registry Variables dashboard, click the variable name, and select View and Edit Details.

Cloning Agent Settings

You may want an agent to have the same settings as another agent. For example, if you add new agents, you may want them to use the same settings as an existing agent. In this case, you can clone the settings from one agent to other agents. This process does not link the agents; in the future if you update the source agent, you also need to update the target agents.

This procedure walks you through selecting the source agent from the Databases dashboard. However, you can also open the Administration dashboard with multiple agents selected. In this case, you select the source agent in Clone Alarm-related Settings to Other Agents dialog box.

Click Settings and then Administration.

Click Set configuration on selected agents.

Click Apply.

Reviewing Rule Definitions

If you want to review the conditions of a rule, open the rule in the Rule Management dashboard.

You can create user-defined rules from the Rule Management dashboard. If you want to modify a rule, we recommend copying the rule and creating a user-defined rule. User-defined rules need to be managed from the Rule Management dashboard; these rules are not displayed in the Alarms view of the Databases Administration dashboard. For help creating rules, open the online help from the Rule Management dashboard.

On the navigation panel, under Homes, click Administration.

Type DBO in the Search field to see the list of predefined rules for Oracle databases.
The Foglight for Oracle rules are displayed. From here, you can review threshold values, alarm counts, and descriptions.
