Defining Alarms

The Alarms global administration screen allows configuring the alarms that are to be invoked for each of Foglight for SQL Azure’s rules.
This screen allows carrying out the following tasks:
•
Reviewing all of the alarms defined for Foglight for SQL Azure—using the Alarms list. For details, see Reviewing all Existing Alarms on page 65.
•
Reviewing and modifying the settings of each alarms—using the Alarms Settings pane. For details, see Viewing and Editing the Alarm Settings on page 66.
•
Configuring the various variables of alarm-triggered email notifications—using the Notification Settings pane. For details, see Configuring Alarm-triggered Email Notifications on page 68.

Reviewing all Existing Alarms

The alarms list displays by default all of the alarms defined for Foglight for SQL Azure. To display a specific alarm, or to search several alarms that are invoked by a similar condition (for example, unavailability), type the requested text in the Search pane.
The alarms are divided into the following categories:
•
Baseline Deviation
•
Locks
•
Operational
•
Storage
Clicking a single group displays all of the alarms that belong to that group in the Alarm Settings and Notification Settings panes, thereby allowing to define alarm-related and notification-related settings for the entire group. For details, see Viewing and Editing the Alarm Settings on page 66.

Viewing and Editing the Alarm Settings

The contents of the Alarms Settings pane change according to the selection made in the Alarms list, as follows:
•
Clicking All Alarms displays all of the currently configured alarms, indicating the alarm title and its status. This view allows handling only the entire set of displayed alarms, using the Enable all or Disable all buttons.
•
Clicking the title of a specific group (for example, Databases or Locks) displays all of the alarms currently configured for this group, indicating the alarm title and its status. This view allows handling only the entire set of displayed alarms, using the Enable all or Disable all buttons.
•
Selecting a specific alarm allows viewing and editing all of the settings defined for the selected alarm.
Figure 9. Alarms Settings pane
In a single alarm view, the Alarm Settings pane comprises the following sections:
•
Alarm Status—indicates whether the alarm is enabled, and allows enabling or disabling the alarm
•
Threshold—displays the thresholds (lower and upper bound) defined for invoking Warning, Critical or Fatal alarms. For details, see Defining Thresholds on page 66.
 
* 
IMPORTANT: While the Alarm Status section is displayed for any selected alarm, threshold settings only appear in certain alarms.

Defining Thresholds

The Threshold section of the Alarms administration screen > Alarm Settings pane allows configuring thresholds for some of the Alarms displayed in the Alarms list.
 
* 
NOTE: None of the alarms that belong to the Baseline Deviation group can have thresholds configured.
When these thresholds are exceeded, Foglight for SQL Azure triggers color-coded alerts, thereby notifying issues of varying severity degree in the monitored environment.
To edit the requested alarm’s severity level bounds:
1
Select the requested alarm from the Alarms list on the left pane.
If the alarm’s severity levels can be edited, they appear on the right pane.
2
Under the Threshold section, click Edit.
Figure 11. The Edit the Severity Level dialog box appears.
3
Type the requested values for the various bounds.
 
* 
IMPORTANT: Ensure typing a value that is within the selected severity level’s range. For example: in most metrics, the value typed as the Medium low bound cannot be smaller than Normal lower bound or greater than the High bound. However, in metrics that indicate normal performance by having a higher value, such as Buffer Pages Free, the value typed as the Medium low bound cannot be greater than Normal lower bound or smaller than the High bound.

Click Set.
The table below displays all alarms whose severity levels can be edited. The default value for each severity level is shown in brackets.
 
* 
NOTE: All of the alarms specified in the table are invoked at both the database and the instance level.
