Display latest activities only in LIVE STREAM

I want to display only 10 latest posts, comments, replies, activities. Only latest. How to configure the widget for that?
I don't want primitive activities of my website (54, 80, 88 days old ones ) to be displayed in a widget called LIVE Stream. Please help me configure it.

Note: Just like the Advertisement Screenshot of this LIVE STREAM plugin: ....David Davidson commented 3 minutes ago, .....Claire Sturges posted a new article 7 min ago.... etc.
