Nmon is a current monitor system performance gadgets, need to be installed first before using with the following command:

1.sudo apt-get install nmon

After installation perform nmon command to open:

1.nmon

nmon can view network usage, CPU, memory and disk.

3. ncdu

ncdu command can be used to view and analysis tools in each directory on the Linux disk space usage, use the following command to install:

apt-get install ncdu

Run the following command to install the analysis from the root directory:

ncdu /

Note: The implementation of the above command will take a lot of disk I / O

After the analysis is complete, it will generate output similar to the following screenshot:

N We can sort the results by name or press s interface sorted by size.

4. slurm

slurm NIC bandwidth monitoring is a command-line utility that automatically generates ASCII graphics output. First use the following command to install before using:

apt-get install slurm

Use the following command output:

slurm -i

slurm interface can perform the following options:
I: Display lx / tx state
c: Switch to Classic interface
r: Manually refresh the screen
q: Quit Tools

5. findmnt

Findmnt Linux is a built-in command line tool, it is mainly used to find the mounted file system state. Findmnt can view the current system of mounting devices, if necessary also for mount or unmount operation.

After executing the command findmnt you will see the following inputs:

Of course, there are the following parameters are available:
findmnt -l: output as a list
findmnt -s: output device mounted in fstab
findmnt -t ext4: by file system type output

6. dstat

dstat is a very flexible tool to use and be used in combination, it can be used to monitor memory, perform, network and disk performance, can be used to replace ifstat, iostat, dmstat other tools. Before use must first run the following command to install:

apt-get install dstat

Run the following command to see all monitoring data:

dstat

Its optional parameter is very large, commonly used are:
dstat -c: Monitor CPU
dstat -cdl -D sda1: Monitor CPU details
dstat -d: Disk Monitor

7. saidar

saidar another CLI system data monitoring and statistics tool that provides information about the disk, network, storage and SWAP monitoring information. You must first use the following command to install before using:
1.sudo apt-get install saidar


After the installation is complete, you can perform saidar output directly, but we usually use parameters command generates output with color:
1.saidar -c

8. ss

ss partial socket statistics, is an alternative to netstat network connections viewer.

Direct execution ss to view it:

Common parameters are:

ss -A tcp: Specifies the protocol View

ss -ltp: displays the process name and PID

9. ccze

ccze very useful, it can use different colors to highlight the log to help administrators analyze and view distinction. You must first use the following command to install before using:

apt-get install ccze

We can use a similar approach to the use of the following:

tailf / var / log / syslog | ccze

The parameters can be viewed using ccze -l log types it supports.

10. ranwhen.py

ranwhen.py Our final presentation is a python tool that can graphically display system activity.

To use the tool you need to install python language support:
sudo apt-add-repository ppa: fkrull / deadsnakes

sudo apt-get update

sudo apt-get install python3.2

Then download ranwhen.py
wget https://github.com/p-e-w/ranwhen/archive/master.zip

unzip master.zip && cd ranwhen-master

Use the following command to execute ranwhen.py
