FreeBSD comes with many different utilities, which can be use to gathered the information as per our requirements like

uname we use this command to print system information including kernel information

dmesg this command print out the kernel ring buffer information.

sysctl finally this command is use to configure kernel run time parameters as well as to read hardware information.

Following all commands you need to gather FreeBSD hardware information.

1) Gathering machine processor architecture:

 # uname -p

2) Gathering the Hardware Type/platform:

 # uname -m

3) Gathering FreeBSD release level:

 # uname -r

We can get all information with single command.

# uname -mrs

Output:

FreeBSD 7.1-RELEASE-p4 i386

4) Gathering information such as processor speed, make etc

 # dmesg | grep CPU

Output::

CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 4000+
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
cpu0:  on acpi0
cpu1:  on acpi0
SMP: AP CPU #1 Launched!

5) Gathering physical & available memory:

 # dmesg | grep memory 

Output::

real memory  = 1878851584 (1791 MB)
avail memory = 1827946496 (1743 MB)

We can also grab the memory information through sysctl:

sysctl -a | grep hw.*mem
sysctl -a | grep mem

Output:

hw.physmem: 194985984
hw.usermem: 167641088
hw.cbb.start_memory: 2281701376

To get rest information of sysctl command

# sysctl -a | less

6) System uptime information including load average:

# uptime

7) If you want to know about system last rebooted or shutdown:

last -1 shutdown
last -1 reboot

Information regarding swap filesystem

# swapinfo -k
