What Condition Trigger Group Status is Equal to Warning

Dear all,

I have set a group alert type at "Advance Alert Manager", this alert will inform me when the following conditions are met

• Group Status is equal to to Warning
• Group status is equal to Critical

For the event message, I have set Group ${GroupName} is ${GroupStatusDescription}, due to ${GroupStatusRootCause}.

The event message is not helpful but only trigger the message that display the  "<<Group>> is in warning state due to member status. <<Device>> is in a warning state."

Whenever I see the event display at my event log, I will go to the particular Device and check on the vital stats which mostly have a Packet Loss of around 10 - 20%.

After the message, my polling status is set to 120 seconds and the another event message display the group status is up.

However my setting for Packet Loss under web admin > Settings > Orion General Thresholds > Percent Packet Loss for warning level is set to 30. 

My questions on the trigger condition :-

1. Under what condition the Warning status will be trigger? Because my warning setting is set to >=30%

Thanks and Regards,
