• To display threshold alerts for all of the Storage Centers, click Select All.
Filter Threshold Alerts by Threshold Denition Properties
You can lter the threshold alerts based on the properties of the threshold denitions that triggered the alerts.
1. Click the Threshold Alerts view.
2. Click the Alerts tab.
3. Use the Filter pane to lter threshold alerts by threshold denition properties.
• To lter the displayed threshold alerts by type (IO Usage, Storage, or Replication) select the Filter Type check box, and then
select the type from the drop-down menu.
• If the Filter Type check box is selected, the Filter Alert Object Type check box can be selected to lter threshold alerts by
the type of storage object selected from the drop-down menu.
• If the Filter Alert Object Type check box is selected, the Filter Denition Type check box can be selected to lter threshold
alerts by the usage metric selected from the drop-down menu.
View the Threshold Denition that Generated an Alert
If you want to view the threshold denition that generated an alert in detail, you can go to the denition directly from the alert.
1. Click the Threshold Alerts view.
2. Click the Alerts tab.
3. Right-click on a current or historical threshold alert and select Go to Denition. The Threshold Denition window appears and
the alert denition that triggered the alert is highlighted.

3. Select the historical alerts to delete from the Historical Threshold Alerts pane.
4. Right-click on the selected alerts and select Delete.
Conguring Volume Advisor Movement Recommendations
Volume Advisor can recommend moving a volume to a dierent Storage Center to improve performance and/or alleviate high
storage usage for a Storage Center. Volume Advisor is congured using threshold denitions, which generate recommendations
along with threshold alerts when error thresholds are exceeded. Volume movement recommendations are calculated based on the
current capacity and past performance of the available Storage Centers.
Threshold Denitions That Support Volume Advisor
Four types of threshold denitions can trigger an alert and a recommendation to move one or more volumes.
Supported Threshold
Denitions Threshold Alert Recommendation
Type Alert Object Type Alert
Denition
IO Usage Storage Center FE IO/Sec When front-end IO for a Storage Center exceeds the congured error threshold,
the alert recommends moving volumes to a specic Storage Center.
IO Usage Volume Latency When latency for a volume exceeds the congured error threshold, the alert
recommends moving the volume to a specic Storage Center, and gives you the
option to act on the recommendation by creating a Live Volume.
IO Usage Controller CPU Usage When CPU usage for a Storage Center controller exceeds the congured alert
threshold, the alert recommends moving volumes to a specic Storage Center.
