NL Compatibility Checker is a free utility that lets you check to see if your network router is compatible with Network Logger Pro and Network Logger IT.   If your router is compatible, you can use Network Logger to graph all the network traffic going through it.  Your router must support SNMP (v1 or v2) or UPnP and have one of those protocols enabled.  Enabling SNMP or UPnP on your router is typically done by logging into your router’s web interface and clicking a checkbox.  See your router’s user manual for more information.   You can find more details by downloading this free utility and going to the Help menu in the app.  The purpose of this utility is to help you decide if purchasing Network Logger Pro is right for you.  Available on the Mac App Store.
