Solved Player counter on screen?

I've noticed on some servers there's a live player count either left or top right, how can I do this?

 

Check this > PlayerCounter

 

Playercounter doesn't show Sleepers

I would use something like UIPlus UiPlus

but for some reason it suddenly shows less sleepers than there should be on my server, not sure what that is about

 

PlayerCounter shows sleepers.

 

Ah yeah you can enable it in the options. Great

 

InfoPanel works as well.
