Vcenter Mail Alarms

Hello everyone!:

I have configured the mail alarms in my vcenter, but when a disk usage alarm is released, the mail is showed with the next message:

Target: IND_MAIL

Previous Status: Gray

New Status: Red

Alarm Definition:

([Yellow metric Is above 107118%; Red metric Is above 1027604%])

Current values for metric/state:

Metric Disk Space actually used = 11924661%

Desription:

Alarm 'Disco Duro VM' on IND_MAIL changed from Gray to Red

I can not understand the percentage shown, I have seen that in other vCenters the message displayed is 90 % or 85 % , but in this case no.

Is there any way to change the way of showing the percentage of the alarm?

Thank a lot!
