3 Click Create Threshold Denition. The Create Threshold Denition dialog box appears.
4 Enter a name for the threshold denition in the Name eld.
5 Select the type of threshold denition to create from the Type drop-down menu.
• IO Usage: Read and write IO performance.
• Storage: Use and growth of storage.
• Replication: Status of replications.
6 Select the type of storage object to assign to the threshold denition from the Alert Object Type drop-down menu.
7 Select the type of usage metric to monitor from the Alert Denition drop-down menu.
8 (Optional) Assign the threshold denition to all of the storage objects that are of the type specied in the Alert Object Type eld by
selecting the
All Objects check box. If you select this check box, it cannot be modied after the threshold denition is created.
9 Specify the alert notication settings for the Error, Warning, and Inform thresholds:
• Error Settings: Enter the threshold value that the usage metric must exceed to trigger an Error threshold alert. To email Error
threshold alerts to the Storage Manager administrators, select the Email check box. Then enter the number of concurrent events
that must occur to trigger an alert email.
• Warning Setting: Enter the threshold value that the usage metric must exceed to trigger a Warning threshold alert. To email
Warning threshold alerts to the Storage Manager administrators, select the Email check box. Then enter the number of concurrent
events that must occur to trigger an alert email.
• Inform Settings: Enter the threshold value that the usage metric must exceed to trigger an Inform threshold alert. To email Inform
threshold alerts to the Storage Manager administrators, select the Email check box. Then enter the number of concurrent events
that must occur to trigger an alert email.
NOTE: Storage Manager sends only one threshold alert email for every 24-hour period. The number of threshold alert
emails per 24-hour period cannot be congured. In addition, if the metric remains at or above the threshold alert value, a
second alert email is not sent. The metric must fall below the threshold value and then exceed the threshold again to
generate an alert email.
10 (Optional) Congure the denition to generate Volume Advisor recommendations to move one or more volumes to a dierent Storage
Center
by selecting the Recommend Storage Center check box.
• Recommendations are generated when the error threshold is exceeded.
• This check box is available only for threshold denitions that support Volume Advisor.
11 To specify the time that Storage Manager monitors the threshold denition:
a Select the Time Constraint check box.
b Enter the start of the time period in the Start Time eld.
c Enter the end of the time period in the End Time eld.
12 To specify which days of the week that Storage Manager monitors the threshold denition:
a Select the Day Constraint check box.
b Select the check boxes of the days of the week to monitor the threshold denition
c Clear the check boxes of the days of the week to not monitor the threshold denition.
13 Click OK to create the threshold denition.
• If you selected the All Objects check box, the threshold denition is created and the Create Threshold Denition dialog box
closes.
• If you did not select the All Objects check box, the Add Objects dialog box appears.
14 Select the storage objects to assign to the threshold denition in the Add Objects dialog box. Additional objects can be added to a
threshold denition after it is created.
