To resovle this issue:
- Connect to the vCenter server using powerCLI VI-Connect cmdlet, see Basic connecting to vCenter or a vSphere Host.
- To list all the alarm definitions:
Get-AlarmDefinition|format-list
- Select an Alarm to modify using ID or Name. Here using a sample ID (Alarm-alarm-97)
- Get the .NET view object for the alarm:
$AlarmtoUpdate=get-view -id (get-alarmDefinition -ID Alarm-alarm-97).id
- To see the current value of Reporting Frequency parameters:
echo $AlarmtoUpdate.info.Setting
- Copy the alarm info item to a spec variable:
$specNewAlarmInfo = $AlarmToUpdate.Info
- modify Reporting Frequency value in the spec variable
$specNewAlarmInfo.Setting.ReportingFrequency = <value in seconds(NOT minute) 0-3600>
- Once the spec variable is updated, it can be written back to the alarm definition:
$AlarmtoUpdate.ReconfigureAlarm($specNewAlarmInfo)
- To validate the changes:
$AlarmtoUpdate=get-view -id (get-alarmDefinition -ID Alarm-alarm-97).id
echo $AlarmtoUpdate.info.Setting
