System utility for monitoring system TCP/IP network connections by application, and connections' status.
PortsMonitor is a network monitoring tool for the Mac. It allows you to see what connections each service and application establish on your Mac.
By default, PortsMonitor auto-refreshes every second, but you can disable this or change the refresh interval. New connections are shown in pop-up windows when the application is auto-refreshing. The main window shows a list of processes, along with their IDs, types, protocols, and ports of each established connection. It also shows the local and remote addresses so that you can know where the connections go.
In my testing, PortsMonitor performed quite well. New connections showed up in the application immediately and all the information seemed accurate.
Pros
- Filtering
- Notification
- Different auto-refresh intervals
Cons
