FreeBSD Statistic Tools
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. |
- fstat
The fstat utility identifies open files.USER CMD PID FD MOUNT INUM MODE SZ|DV R/W ronald fstat 1087 root / 2 drwxr-xr-x 512 r ronald fstat 1087 wd /usr 824321 drwxr-xr-x 3584 r ronald fstat 1087 text /usr 1038656 -r-xr-sr-x 14624 r ronald fstat 1087 0 /dev 126 crw--w---- ttyp1 rw ronald fstat 1087 1 /dev 126 crw--w---- ttyp1 rw ronald fstat 1087 2 /dev 126 crw--w---- ttyp1 rw ronald fstat 1087 3 /dev 15 crw-r----- mem r ronald fstat 1087 4 /dev 16 crw-r----- kmem r ronald fstat 1087 5 / 8700 -rw-r--r-- 40960 r ronald vim 1025 root / 2 drwxr-xr-x 512 r ronald vim 1025 wd /tmp 2 drwxrwxrwt 512 r ronald vim 1025 text /usr 329983 -rwxr-xr-x 1266616 r ronald vim 1025 0 /dev 129 crw--w---- ttyp3 rw ronald vim 1025 1 /dev 129 crw--w---- ttyp3 rw
- gstat
