Spruce Up tools to view amount of Free Memory and Disk Usage

URLs:

https://puppylinux-or-pcbsd.blogspot.com/   Here is my source list of Free Memory Tools

Tools to check Free Memory available and How much SWAP memory is used

Use a perl shell script made for BSDs:

You can use this script.

# fetch http://www.cyberciti.biz/files/scripts/freebsd-memory.pl.txt
# mv freebsd-memory.pl.txt /usr/local/bin/free
# chmod +x /usr/local/bin/free
# perl --version
# whereis perl
# vi /usr/local/bin/free        change first line #!/usr/bin/perl   to #!/usr/local/bin/perl
# free
Linux like free command for my FreeBSD server
Freecolor is a free replacement that displays free memory graphically as a bargraph. It supports the same options as free. Install freecolor, enter:
# cd /usr/ports/sysutils/freecolor
# make install clean
OR
# pkg install freecolor
To see memory details, enter:
$ freecolor -m -o

  2. Inact: number of bytes inactive.
  3. Wired: number of bytes wired down, including BIO-level cached file data pages.
  4. Cache: number of clean bytes caching data that are available for immediate reallocation.
  5. Buf: number of bytes used for BIO-level disk caching.
  6. Free: number of bytes free.

$ top


Installing htop on FreeBSD

First, make sure you system is up to date (see how to install sudo on FreeBSD or use the su - command to gain root access):
$ sudo pkg update
$ sudo pkg upgrade
Finally, run the following to install htop on FreeBSD:
$ sudo pkg install htop



 # vmstat
 procs    memory    page                      disks     faults       cpu
 r  b  w  avm  fre  flt  re  pi  po   fr   sr da0 pa0   in   sy   cs us sy id

You can avoid Perl based code and use standard sh shell to get same info using freebsd-memory.sh script:
$ fetch https://raw.githubusercontent.com/ocochard/myscripts/master/FreeBSD/freebsd-memory.sh
## or use curl command ##
## $ curl -O https://raw.githubusercontent.com/ocochard/myscripts/master/FreeBSD/freebsd-memory.sh
$ sh freebsd-memory.sh
Outputs from my FreeBSD based home router:
