DevOpsFetch

DevOpsFetch is a tool designed with Python exclusively for DevOps professionals to collect and display essential system information. This tool supports retrieving details about active ports, Docker containers, Nginx configurations, user logins, and system activities within a specified time range. Additionally, it offers continuous monitoring and logging capabilities via a systemd service.

Objective

To develop a tool that provides:

• Active ports and services
• Docker images and container statuses
• Nginx configurations
• User logins and details
• System activities within a time range

Requirements

Information Retrieval

1. Ports:

   • -p or --port: Display all active ports and services.
   • -p <port_number>: Provide detailed information about a specific port.

2. Docker:

   • -d or --docker: List all Docker images and containers.
   • -d <container_name>: Provide detailed information about a specific container.

3. Nginx:

   • -n or --nginx: Display all Nginx domains and their ports.
   • -n <domain>: Provide detailed configuration information for a specific domain.

4. Users:

   • -u or --users: List all users and their last login times.
   • -u <username>: Provide detailed information about a specific user.

5. Time Range:

   • -t or --time: Display activities within a specified time range in the format YYYY-MM-DD HH:MM:SS,YYYY-MM-DD HH:MM:SS.

Output Formatting

• Outputs are formatted in well-structured tables for clarity, with descriptive column names and text wrapping to ensure readability.

Usage

DevOpsFetch can be used with various command-line flags:

Port Information

• Display all active ports:

sudo devopsfetch -p

• Display information for a specific port:

sudo devopsfetch -p 80

Docker Information

• List all Docker images and containers:

sudo devopsfetch -d

• Display information for a specific container:

sudo devopsfetch -d my_container_name

Nginx Information

• Display all Nginx domains and their ports:

devopsfetch -n

#- Display configuration for a specific domain

devopsfetch -n example.com

User Information

• List all users and their last login times:

sudo devopsfetch -u

Time Range Activities

• Display system activities within a specified time range:

sudo devopsfetch -t "YYYY-MM-DD HH:MM:SS,YYYY-MM-DD HH:MM:SS"

Help

• Display usage instructions:

sudo devopsfetch -h

Logging Mechanism

DevOpsFetch uses systemd for logging. Logs are stored in the system journal and a dedicated log file.

To view the systemd service logs:

sudo journalctl -u devopsfetch.service

To view the dedicated log file:

sudo cat /var/log/devopsfetch.log

Logging Logs for continuous monitoring are stored in /var/log/devopsfetch.log. To view the logs, you can use:

sudo cat /var/log/devopsfetch.log
