System Monitoring¶
The data and information that pfSense® software collects and displays is every bit as important as the services it provides. Sometimes it seems that commercial routers go out of their way to hide as much information as possible from users, but pfSense software can provide almost as much information as anyone could ever want (and then some).
This chapter contains a variety of methods for finding information about the firewall status, logs, traffic, hardware, and so on.
