Hi abhijith891 , you could do from CLI (as well ASDM): show traffic, show interface outside and show perfmon for check what traffic it's generating alarms.

Also, you could check if you need block some traffic that you don't need. Sometimes some users don't' care about bandwidth...

And finally, the worst, you should check if your device it is the correct one for your environment.

The following links should help you with troubleshooting.
