HP VAN SDN Controller Administrator Guide v3

2.2.5 Managing the Alert Policy
There is no configurable limit to the number of alerts maintained in persistent storage. Instead, the
default policy is to maintain alerts in persistent storage for 14 days, and then delete them. The
background task to delete alerts runs once a day by default. To change the policy, use the
Configurations tab in the GUI. The configuration options for maintaining alerts include:
trim.alert.age Specifies the number of days an alert remains in persistent storage. Default:
14 days.
trim.enabled Enables or disables removal of alerts that have reached the age-out-days
limit. Default: true (enabled).
trim.frequency The frequency in hour per-day for trimming (deleting) alerts that have
reached the trim.alert.age limit.
2.2.5.1 Configure the Alert Age-Out Policy
Alerts cannot be selectively deleted, but are removed by an age-out policy configured in the
com.hp.sdn.adm.alert.impl.AlertManager configuration component.
1. Click on Configurations.
2. Click on the com.hp.sdn.admalert.impl.AlertManager component to display the
