Monitoring software on Linux, i-Nex ('CPU-Z'), Psensor, top
 

I'm a newbie on Linux, so I just wanted to share my results while searching for monitoring software on Ubuntu. If I missed any useful ones, please let me know.

[B]CPU[/B]
Basic CPU info by:
[code]
cat /proc/cpuinfo
[/code]Available frequencies of CPU to the OS:
[code]
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
[/code]Current frequency (default updates every 2,0 sec) in terminal:
[code]watch -d "cat /proc/cpuinfo | grep -i Mhz"[/code]or install a small program to watch and set the CPU frequency called indicator-cpufreq:
[code]
sudo apt-get install indicator-cpufreq
[/code][B]System Monitoring[/B]
Top; a lightweight prog that is almost always included in distros and runs in the terminal:
[code]
top
[/code]Gnome system monitor (included in Ubuntu) which has a nice interface:
[code]
gnome-system-monitor[/code][B]Hardware monitoring[/B]
Psensor, on Ubuntu:
[code]sudo apt-get install psensor[/code]or for the latest Psensor, which includes Hard Disk temp, add these:
[code]sudo add-apt-repository ppa:jfi/ppa
sudo apt-get update[/code]Also found a CPU-Z like alternative for (Ubuntu 14.04+) called "i-Nex" which reports on the CPU, Motherboard, GPU and Memory:
[code]
sudo add-apt-repository ppa:i-nex-development-team/daily
sudo add-apt-repository ppa:gambas-team/gambas3
sudo apt update
sudo apt install i-nex[/code]Licence: GNU GPL 3

[code]
sudo lshw
[/code]will give you a very detailed look at your system.

cat /proc/cpuinfo, unfortunately, doesn't distinguish between cores and threads.

if, of interest:
[code]
cat /proc/meminfo
[/code]will give a bit of memory info.

[code]
df -h
[/code]will give you disk(s) info in human readable (-h) form.

disk utility and gparted will allow you see very detailed information about all the media and media devices. It will also allow you to easily destroy the data, if you are not careful.

edit: gparted can actually be used to change partition sizes, but again, it must be done carefully, realizing that even then, there is a risk of data loss. Always keep off-system backups of any important data!

I use:
[code] uptime [/code] To see system load.

[code]
sensors [/code] for system temperatures.

[code]
nvidia-smi [/code] to see what my GPU is doing.

I'm usually SSHing onto a system to check it so command line tools are more use than GUI tools. Also most of my systems run OpenSUSE so I can't guarantee they work on Ubuntu.

I've also come across
[code]
acpi [/code] which gives battery state for my laptop among other things.

In all cases read the man page for them to see what they do.

For many kinds of work, tcpdump and/or wireshark can be invaluable.

The latest Linux Format suggests using hardinfo, lspci, dmidecode and biosdecode to get hardware into.
