Storage Center Threshold Alerts

Threshold alerts are automatically generated when user-dened threshold denitions for storage object usage are crossed. Threshold

queries allow you to query historical data based on threshold criteria.

Conguring Threshold Denitions

Threshold denitions monitor the usage metrics of storage objects and generate alerts if the user-dened thresholds are crossed.

The types of usage metrics that can be monitored are I/O usage, storage, and replication. Storage Manager collects the usage metric data

from managed Storage Centers. By default, Storage Manager collects /IO 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 denitions and each threshold

denition 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 congured on the Data Collector, Storage Manager sends an email with the threshold alert. It sends only one email alert

every 24 hours.

NOTE: Storage Manager 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 denitions:

• Setting Up Threshold Denitions

• Assigning Storage Objects to Threshold Denitions

• Assigning Threshold Denitions to Storage Objects

• Viewing Threshold Alerts for Threshold Denitions

Setting Up Threshold Denitions

You can create, view, edit, and delete threshold denitions.

Create a Threshold Denition

Create a threshold denition to monitor IO usage, storage, or replications.

Prerequisites

To receive email notications for threshold alerts, the following email settings must be congured:

• SMTP server settings for the Data Collector

• Email address for your user account

• Notication settings for your user account

About this task

Storage Manager generates threshold alerts after Storage Usage checks usage metrics and notices a threshold denition has been

exceeded. Storage Usage runs daily at 12 AM by default.

Steps

1 Click the Threshold Alerts view.

2 Click the Denitions tab.
