Notification only for ping service

Hello,
I have 4 routerboards and im monitoring all of them. I seted up the notification feature in order to send me sms messages to my cellphone for Up and Down. The problem that i have is that i received 5 sms for each one. That is 1 for Http, 1 for Telnet, 1 for SSH, 1 for Ping and 1 for FTP.
I delete all the service but ping in all the devices service tab cause i want to received only 1 sms for ping problem. But still getting sms for all the services. Can someone help me with that.

Thanks !

How did you create the SMS Notification? How you do it?

This could take a while since you have to do it individually on each device. Open the services list, Double click the device with the service you don’t want notification from, On the Notification tab,select; Use notification, uncheck all possible notifications.
