[Receive notifications if a PC/Server is down]

How do I enable PUSH notifications for my Samsung S5 smartphone?

[Receive notifications if a PC/Server is down]

I could use a little more assistance.  I am monitoring the server and it was shut down the other day.  I did not receive a text alert to my smartphone (which has the app installed on it.) 

Specifically, where would I set up the notification.  On the phone or the Pulseway app online.

Depending on which location, where would I click to add this notification option to get texts to my phone that the server is offline?

Thanks.

How can I get a notification if one of my monitored servers is down?  Also, can I set alerts to only be allowed at certain times of the day?
