Thresholds
Threshold alerts are automatically generated when user-defined threshold definitions for storage object usage are crossed.
Threshold queries allow you to query historical data based on threshold criteria.
Configuring Threshold Definitions
Threshold definitions monitor the usage metrics of storage objects and generate alerts if the user-defined thresholds are
crossed.
The types of usage metrics that can be monitored are I/O usage, storage, and replication. Unisphere Central collects the usage
metric data from managed Storage Centers. By default, Unisphere Central collects I/O usage and replication metric data every
15 minutes and storage usage metric data daily at 12 AM. Storage objects on the Storage Centers are assigned to threshold
definitions and each threshold definition contains one or more threshold values. When the value of a monitored metric reaches
a threshold value, an alert occurs. If an SMTP server is configured on the Data Collector, Unisphere Central sends an email with
the threshold alert. It sends only one email alert every 24 hours.
NOTE:
Unisphere Central sends only one email per alert occurrence. If after 24 hours the metric is still at or above the
threshold alert value, an alert email is not sent. The metric must fall below the threshold value and then exceed the
threshold again to generate an alert email.
Perform the tasks in the following sections to set up and view threshold definitions:
