- Internet access for installing tools
1. htop – Interactive Process Viewer
The htop tool is a powerful interactive process viewer and a must-have for Linux users. It provides a real-time overview of system processes, CPU usage, memory consumption, and swap memory usage.
Installation:
sudo apt install htop # For Debian/Ubuntusudo yum install htop # For CentOSUsage:
htopNavigate using the arrow keys and use F9 to kill processes. This allows you to manage system resources effectively.
2. ioping – Disk I/O Monitoring
ioping is a simple tool that allows you to monitor disk I/O performance in real time. This tool helps in identifying slow disks or partitions that may be contributing to poor system performance.
Installation:
sudo apt install iopingUsage:
ioping -c 10 .This command checks the disk I/O performance of the current directory.
3. Netdata – Real-time Performance Monitoring
Netdata is a real-time performance monitoring tool that provides comprehensive metrics on system health, including CPU usage, disk activity, and network performance. It’s visually appealing and user-friendly.
Installation:
bash <(curl -Ss https://my-netdata.io/kickstart.sh)Usage:
Access it via your web browser at http://localhost:19999 to analyze the performance metrics live.
4. vnStat – Network Traffic Monitor
vnStat is a network traffic monitor that keeps track of network usage over time, allowing you to analyze data consumption trends and manage bandwidth effectively.
Installation:
sudo apt install vnstatUsage:
vnstatThis will give you a summary of your network usage statistics.
5. Gatling – Load Testing
Gatling is essential for testing performance under load, helping developers understand how applications behave under stress. It’s especially handy for simulating multiple users interacting with web applications.
Installation:
curl -OL https://github.com/gatling/gatling/releases/latest/download/gatling-charts-highcharts-bundle-.zipUsage:
Run your simulation scripts directly through the terminal to generate performance reports.
Troubleshooting Common Issues
- If
htopdoesn’t display correctly, ensure your terminal supports it. - For installation issues, check your internet connection and repository settings.
- Run
sudo service netdata restartif Netdata is not displaying data.
Summary Checklist
- Install the listed tools based on your system distribution.
- Use each tool to monitor specific areas of system performance.
- Regularly check performance metrics to identify and resolve issues early.
- Analyze trends over time for proactive performance management.
