Monitoring System Resources with Shell Scripts
This tutorial explores how to monitor system resources using shell scripts, enabling administrators to track performance metrics and manage system health effectively.
1. CPU Monitoring
Shell scripts can be used to monitor CPU usage, allowing administrators to track processor load and identify performance bottlenecks.
Example:
Check CPU usage:
top -n 1 -b | grep "Cpu(s)"
2. Memory Monitoring
Monitoring memory usage helps administrators ensure optimal system performance and detect memory leaks or excessive usage.
Example:
Check memory usage:
free -m
3. Disk Monitoring
Shell scripts can monitor disk usage and disk space to prevent storage issues and manage disk capacity effectively.
Example:
Check disk space:
df -h
4. Network Monitoring
Monitoring network activity and bandwidth usage helps administrators identify network performance issues and optimize network resources.
Example:
Monitor network connections:
netstat -tulpn
5. Process Monitoring
Shell scripts can monitor running processes to track resource usage and manage process execution effectively.
Example:
List running processes:
ps aux
6. Conclusion
Monitoring system resources with shell scripts provides administrators with essential tools to maintain system health, optimize performance, and ensure efficient operation of computing environments.
