A Shell Script to Monitor Network, Disk Usage, Uptime, Load Average and RAM Usage in Linux

The duty of System Administrator is really tough as he/she has to monitor the servers, users, logs, create backup and blah blah blah. For the most repetitive task most of the administrator write a script to automate their day-to-day repetitive task. Here we have written a shell Script that do not aims to automate the task of a typical system admin, but it may be helpful at places and specially for those newbies who can get most of the information they require about their System, Network, Users, Load, Ram, host, Internal IP, External IP, Uptime, etc.

How Do I Install and Run Script?

First, use following wget command to download the monitor script "tecmint_monitor.sh" and make it executable by setting appropriate permissions.

# wget http://tecmint.com/wp-content/scripts/tecmint_monitor.sh
# chmod 755 tecmint_monitor.sh

It is strongly advised to install the script as user and not as root. It will ask for root password and will install the necessary components at required places.

To install "tecmint_monitor.sh" script, simple use -i (install) option as shown below.

./tecmint_monitor.sh -i 

Enter root password when prompted. If everything goes well you will get a success message like shown below.

Congratulations! Script Installed, now run monitor Command

After installation, you can run the script by calling command 'monitor' from any location or user. If you don’t like to install it, you need to include the location every-time you want to run it.

# ./Path/to/script/tecmint_monitor.sh

Now run monitor command from anywhere using any user account simply as:

$ monitor

As soon as you run the command you get various System related information which are:

1. Internet Connectivity
2. OS Type
3. OS Name
4. OS Version
5. Architecture
6. Kernel Release
7. Hostname
8. Internal IP
9. External IP
10. Name Servers
11. Logged In users
12. Ram Usages
13. Swap Usages
14. Disk Usages
15. Load Average
16. System Uptime

Check the installed version of script using -v (version) switch.

$ monitor -v
