Data Retention Policies
Data Retention Policies allow Administrators to define the duration that they wish
to keep each kind of data. The policies are executed once every twenty-four
hours by the STM Collector service. Data Retention Policies are divided into the
following categories:
• Backup
• Database
• Events
• Operating Systems
• SMI-S
• SNMP/FC/HBA
• System
• Virtualization
These categories are subdivided into types of data. Each type of data may have
a retention policy for raw and hourly data.
When the Data Retention Policy is enforced once a day, old data will be removed
from the database.
For example: You have configured Operating Systems > Disk Usage > Raw
Data for "3 months." When this policy is enforced, ALL disk usage data for ALL
devices older than 3 months will be deleted.
If you select Forever, data will never be deleted
