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 IO 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.
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.
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.
