Alarms Overview
Overview of alarm components and features.
Alarms and notifications allow the site administrator to monitor the state of the storage system by receiving automated messages about the metrics monitored by the View for ClusterStor™ server. An alarm records the state of the system as indicated by the values in specified metric series.
Alarms are created automatically by View for ClusterStor based on alarm definitions. As new values are added to a metric series, the state of the alarm updates automatically to reflect the most recent values.
An alarm is defined by a set of one or more inequality comparisons of a monitoring subsystem metric value with a threshold value. An alarm definition specifies the type of metric series that the alarm will monitor, the threshold values for determining what the state of the alarm should be, and the frequency for checking the metric series for changes to the metric values.
View for ClusterStor installs several pre-defined alarm definitions. The threshold values for these alarms can be modified by the site administrator. Additional site-local alarm definitions can also be created.
| Alarm State | Description |
|---|---|
| OK | Indicates that the alarm threshold has not been reached. |
| Alarm | Indicates that the alarm threshold has been exceeded. |
| Undetermined | Indicates that the metric series did not receive a new value when expected. |
A notification email is a message sent automatically when the state of an alarm changes. The alarm definition specifies which notifications will be sent when the state of an alarm changes.
To disable notifications, the email address can be changed to root@localhost. For more information, see Configure Notification Email.
