Monitoring

By navigating to System | Monitoring, you can view another useful set of data relating to the real time operation of your pfSense system. There are two sections on this page: a graph (Interactive Graph) and a summary of the information in the graph (Data Summary). There are several pieces of information available on this page, and they relate to the percentage of CPU usage attributable to different processes:

User util.: User-related processes
Nice util.: Nice (low-priority) processes
System util.: Non-nice system processes
Interrupt: System interrupts

There is also a column representing the grand total of processes. Each entry includes the minimum, maximum, and average percentage of CPU usage for each category.
