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:

•
Configuring an email server
•
Defining Default Email settings
•
Defining email notifications, recipients, and messages
•
Defining variables to contain email recipients
•
Defining scheduled email notifications
Configuring an email server

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.

Defining Default Email settings

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.

Enabling or disabling email notifications

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:

•
The alarm email notification setting is enabled for the affected rule.
•
The alarm is triggered by changes in the monitored environment.
•
Alarm notification is enabled at the triggered severity level. See Defining email notifications, recipients, and messages .
To enable or disable email notifications:
1
In the Alarms view, click the Settings tab.
2
Decide on the scope for the change: all alarms, a category of rules, or a selected rule.
3
Complete the steps for the selected scope:

Defining variables to contain email recipients

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.

To create a registry variable:
1
On the navigation panel, under Dashboards, click Administration > Rules & Notifications > Manage Registry Variables.
2
Click Add.
The New Registry Variable Wizard opens.
3
Select the registry variable type String, and click Next.
4
In the Name field, enter a name, for example: EmailTeamName
Optional — Add a description.
5
Click Next.
6
Select Static Value.
7
In the Enter desired value box, enter one or more email addresses (separated by commas).
* 
NOTE: Email groups are not permitted.
8
Click Finish.
The Edit Registry Variable dashboard displays the newly created registry variable.
To use a registry variable in email notifications, type the variable name between two hash (#) symbols, for example: #EmailTeamName#. For more information, see Defining email notifications, recipients, and messages .
Defining scheduled email notifications

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.

To schedule the sending of email notifications for a registry variable:
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.
2
In the Performance Calendars List table, click Add.
The Performance Calendar Wizard opens.
3
Select a schedule, for example: End of Day
4
Click Next.
5
Select Static Value.
6
In the Enter desired value box, enter one or more email addresses (separated by commas) that should received email notifications based on the schedule.
* 
TIP: The addresses may the same as or different from those assigned to the registry variable.
7
Click Finish.
The Edit Registry Variable dashboard displays the newly created schedule. If desired, repeat to add other schedules.

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.

To clone alarm-related settings:
1
On the Databases dashboard, select the check box for the agent with the settings you want to clone.
2
Click Settings and then Administration.
3
In the Administration dashboard, click Alarms.
4
Click Set configuration on selected agents.
The Clone Alarm settings cross agents dialog box opens.
5
In the Select the source agent drop-down list, you should see the agent you selected.
6
In the Select the target agents table, select the check boxes for agents that should inherit settings from the source agent.
7
Click Apply.
8
When prompted for confirmation, click Yes.

Reviewing Rule Definitions

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

* 
IMPORTANT: Avoid editing Foglight for Azure SQL Database rules in the Rule Management dashboard. These rules may be modified during regular software updates and your edits will be lost. Always use the alarm templates to modify rules.

You can create user-defined rules from the Rule Management dashboard. If you want to modify a rule, it is recommended to copy the rule and create 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, refer to the online help from the Rule Management dashboard.

To open the Rule Management dashboard:
1
On the navigation panel, under Homes, click Administration.
2
In the Rules & Notifications dashboard, click Rules.
3
Type Azure in the Search field to see the list of predefined rules for Azure SQL databases.
The Foglight for Azure SQL Database rules are displayed. From here, you can review threshold values, alarm counts, and descriptions.
4
To see the full rule definition, click a rule and then click View and Edit.
5
In the Rule Detail dialog box, click Rule Editor.
6
When you are done your review, click Rule Management in the breadcrumbs to return to the dialog box.

Defining Connection Details

Use the Connection Details category to define global connection settings, which apply to all instances and hosts selected in the view. You can enable user-defined collections and set VMware connection details.

* 
NOTE: The following sections instructs how to define the connection settings for monitored Azure SQL databases.
Defining the Connection Settings for the Monitored Azure SQL databases

The Connection Details view contains a table that displays all the agents that were selected before entering the Databases Administration dashboard.

To define the connection settings for the requested agents:
1
Select the check boxes to the left of the agents for which uniform credentials are to be set. To cancel the selection, click Select None and select again.
2
Click Set Credentials.
The Edit Instance Credentials dialog box opens.
3
Use the Connection Details section to enter or accept the default port (1433).
4
Use the Specify Login Credentials section to select the type of authentication, specify the user name and the password used for connecting to the Azure SQL Database.
5
Click Set to proceed to the next stage of validating the database’s connectivity.
Validating Connectivity and Starting to Monitor the databases

After setting the default credentials for the host, these newly created credentials can now be used by the wizard to attempt to log in to the databases.

To validate the databases’ connectivity:
1
Click Test connection.
The Verifying Connectivity progress bar appears.
At the end of this process, any connectivity issues are listed in the Status column of the database table. When the connection is successful, the Status column displays the status message Validated, which indicates that the database connected successfully and the specified Azure SQL user has the required permissions.
If the connection failed verification, the Status column displays one of several connectivity status messages.
The messages, causes, and appropriate responses are:
•
Invalid username/password — check the credentials and try again.
•
Incorrect port— check if the SQL Azure port is correct and try again.
•
Wrong Database Credentials — modify the login credentials.
•
Insufficient Privileges — grant the user the privileges required for connecting to the database, by clicking the status Insufficient Privileges.
The Insufficient Privileges dialog box opens.
Use this dialog box to specify a Server Admin user with sufficient privileges.
Select the type of authentication. Type a Server Admin user and password, and then click Grant privileges.
If the Server Admin credentials entered were incorrect, the column displays the status Wrong Sysadmin credentials.
After correcting the mistakes that resulted in the connectivity failure, click again Validate connectivity.
2
Click Validate connectivity on the status bar.
3
Click Save Changes.
The Applying Modified Settings progress bar appears.
