Chrome inspector does not show network requests path and etc

I use AJAX and want to visit its behaivour while sending request to server through Chrome Inspector. When I switch to Network tab of inspector, requests not listing there.

Edit

Inspector is open and network tab is active, now I'll do something to trigger ajax request, but no report in inspector. I mean the situation is fully ready for inspector to show results, but some configuration should be changed.

As I said some configuration changed. All I need to do is click on filter icon (it's active when it's color is blue).
And then select the type of request I want to see. Default option is to select All or just to visit xhr request, select xhr.
