Why Monitoring & Managing Processes is Essential in RHEL

Monitoring and managing processes is super important in RHEL system administration. Here’s why it matters:

1. System Stability & Performance

• Optimize System Resources: Make sure everything runs smoothly by keeping an eye on processes.

• Identify & Resolve Issues: Spot any resource-hogging processes quickly. Then, take action to maintain system performance.

2. Security & Compliance

• Monitor Network Activity: Capture and analyze network packets to identify suspicious activity and secure your network.

• Ensure Compliance: Managing processes properly helps meet all security needs.

3. Efficient System Management

• Streamlined Process Monitoring: Easily view and manage all those processes, file usage, & connections. It makes your system more secure!

• User Accountability: Keep track of who’s doing what in the system. This ensures everyone uses resources responsibly.

4. Preparation for RHCSA Certification

• RHCSA Exam Objectives: Get familiar with skills that matter for process monitoring—these are key parts of the RHCSA exam!

• Real-World Applications: The skills you learn here are useful beyond exams! They’re essential for handling RHEL systems daily.

The Importance of Monitoring & Managing Processes Using CLI in RHEL
