A simple shell script for monitoring in Linux

A simple shell script for monitoring in Linux

The task of the system administrator is really difficult, because he/she must monitor servers, users, logs, create backups, and so on. For most repetitive tasks, most administrators write an automated script to repeat these tasks day after day. Here, we have written a shell script for you to automate the general tasks to be completed by the system administrator. This may be useful in most cases, especially for new users, they can use this script to obtain most of the information they want, including systems, networks, users, loads, memory, hosts, internal IP addresses, external IP addresses, and boot time.

We have noticed and formatted the output (to some extent ). This script does not contain any malicious content and can be run as a normal user account. In fact, we recommend that you run the script as a common user instead of the root user.

Monitor Linux System Health Shell scripts

The following code can be freely used, modified, and re-distributed without retaining the honors that Tecmint and script authors deserve. We have tried to customize the output results to a certain extent. NO content is generated except for the required output content. We have also tried to use variables that are usually not used in Linux systems. These variables should be usable at will.

Minimum System Requirements

Everything you need is a running Linux machine.

Dependency

For a standard Linux release, using this package does not require any dependency. In addition, this script does not require the root permission for execution. However, if you want to install it, you must enter the root password once.

Security

We also pay attention to system security issues. Therefore, when installing this package, you do not need to install any additional packages or run it with root access permissions. In addition, the source code is published using the Apache 2.0 license, which means that as long as you retain the copyright of Tecmint, You can freely edit, modify, and then distribute the code.

 

How to install and run scripts?

First, use the wget command to download the monitoring script.“tecmint_monitor.sh”To give it appropriate execution permissions.

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