Re: OEM 12c (12.1.0.5) generating too many alerts on Metrics "Logons Per Sec"

Hi Kellyn, Jonathan,Mladen,Thank you all for the reply. Here are some answer to some of your points.

I never had this type of flooding alerts in OEM 11g. It is happening for each of my server(host) not from one ow two. So I would like to disable this alert if there is an option. Ideally it maybe good to investigate why so many logins happening but it is very hard for me to spend time to do that instead I would like to simply disable it.
Any further tips will be appreciated.
