On this page I provide a list of statistical tools for FreeBSD to monitor your
system. There are a lot of them, so if I missed one please mail me (ronald at
echteman dot nl).
| fstat | The fstat utility identifies open files. |
| gstat | The gstat utility can be used to monitor I/O transactions of geom(4) devices. |
| iostat | The iostat utility displays kernel I/O statistics on terminal, device and cpu operations. |
| netstat | The netstat command symbolically displays the contents of various network-related data structures. |
| nfsstat | The nfsstat command displays statistics kept about NFS client and server activity. |
| pstat | The pstat utility displays open file entry, swap space utilization, terminal state, and vnode data structures. |
| top | Top displays the top processes on the system and periodically updates this information. |
| systat | The systat utility displays various system statistics in a screen oriented fashion. |
| vmstat | The vmstat utility reports certain kernel statistics kept about process, virtual memory, disk, trap and cpu activity. |

- netstat
The netstat command symbolically displays the contents of various
network-related data structures. There are a number of output formats,
depending on the options for the information presented.
