# wall_monitoring
This Bash script provides a concise and informative summary of important system statistics and status. It outputs various details about your system, including architecture, CPU, memory usage, disk usage, network configuration, and more.
---
## **Features**
The script gathers and outputs the following system information:
- **System Architecture and Kernel Version**
Displays system architecture (e.g., x86_64) and kernel version.
- **Physical CPU Processors**
Counts and displays the number of physical CPU processors.
- **Virtual CPU Processors (VCPUs)**
Displays the number of virtual CPU processors in the system.
- **Memory Usage**
Shows the used and total system memory, along with the percentage of memory usage.
- **Disk Usage**
Displays the used and total disk space on the root file system along with the usage percentage.
- **CPU Load**
Displays the current CPU load percentage (excluding idle time).
- **Last Boot Time**
Shows the date and time of the last system reboot.
- **LVM Status**
Checks and shows whether LVM (Logical Volume Manager) is being used on the system.
- **Active TCP Connections**
Displays the number of established TCP connections on the system.
- **User Logins**
Counts the number of users logged in, based on the `/etc/passwd` file.
- **Network Information**
Shows the system's IPv4 address and MAC address.
- **Sudo Command Usage**
Displays the number of sudo commands executed on the system, based on the sudo log.
---
## **Installation**
No installation is required. Simply copy the script and execute it on your Linux system.
---
## **Usage**
### **Running the System Info Script**
1. **Clone or Copy the Script**
Copy the contents of the `monitoring.sh` script or clone it from the repository to your system.
2. **Give Execution Permissions**
Make sure the script has executable permissions:
```bash
chmod +x monitoring.sh
```
3. **Run the Script**
Execute the script by running the following command in your terminal:
```bash
sudo ./monitoring.sh
```
### **Launcher Script**
In case you want to automate the monitoring process and display the system information to all users using `wall`, you can use the `launcher.sh` script.
1. **Copy the `launcher.sh` Script**
The `launcher.sh` script launches the `launcher.sh` script and broadcasts the output to all users.
2. **Give Execution Permissions to the Launcher Script**
Ensure the launcher script has execution permissions:
```bash
chmod +x launcher.sh
```
3. **Run the Launcher Script**
Execute the launcher script to generate and broadcast the system information:
```bash
sudo ./launcher.sh
```
- This will run `monitoring.sh` (or `launcher.sh`) and direct the output to a temporary file `output`.
- The `wall` command is then used to broadcast the output to all logged-in users.
- Finally, the `output` file is deleted.
### Automated Display Using `watch`
To automate the display of system statistics across multiple machines, you can set up a recurring display with the following command:
```bash
watch -n 10 sudo ./launcher.sh
```
### Explanation:
- `watch`: This command runs the specified command at regular intervals.
- `-n 10`: This sets the interval to 10 seconds (you can adjust the value as needed).
- `sudo ./launcher.sh`: This runs the `launcher.sh` script, which in turn executes `monitoring.sh`, generating system statistics and broadcasting them to all users via the `wall` command.
By using this, you'll automatically broadcast updated system information on all machines every 10 seconds (or whatever interval you choose). This can be useful for continuous monitoring or displaying real-time status updates on multiple systems in a network.
---
This setup works well for showing live system data across all logged-in users, creating an automated dashboard that can be seen on every computer in the network.
### Output:
The script will provide a system report with sections like:
```
#ARCHITECTURE: x86_64
#CPU PHYSICAL: 4
#VCPU: 4
#MEMORY USAGE: 1234/4096MB (30.23%)
#DISK USAGE: 15/100GB (10%)
#CPU LOAD: 20.0%
#LAST BOOT: 2025-01-01 12:00:00
#LVM USE: yes
#TCP CONNECTIONS: 12 ESTABLISHED
#USER LOG: 4
#NETWORK: IP 192.168.1.1 (00:14:22:01:01:01)
#SUDO: 25 cmd
```

## **Dependencies**
This script relies on the following tools:
- `uname`
- `grep`
- `cut`
- `awk`
- `bc`
- `df`
- `top`
- `last`
- `lvm`
- `netstat`
- `ifconfig`
- `wall` (for broadcasting)
All of these tools are typically pre-installed on most Linux distributions.
