Recommended CentOS Stream 8 system monitoring tool
CentOS Stream 8 provides a variety of monitoring tools to meet different monitoring needs. This article recommends several commonly used tools and briefly introduces their functions:
System performance monitoring
- top: Displays the usage of system process resources in real time, and is the most commonly used performance monitoring tool in Linux systems.
- htop: The enhanced version of the
topcommand provides a more intuitive interface and interactive functions, and supports mouse operation. - vmstat: Reports information on virtual memory, processes, CPU activities, etc., and is used to monitor the overall performance of the system.
- iostat: Monitors the usage of system I/O devices, which is especially suitable for analyzing storage device performance.
- free: Check the system memory usage, including physical memory, swap memory and cache.
- sar: Collect, view and record system performance data, which can be used for long-term performance analysis.
Network monitoring
- iftop: Monitor network traffic in real time and visually display network traffic.
- tcpdump: Packet capture tool for network traffic analysis and problem diagnosis.
- nmcli: NetworkManager command line interface for managing network connections and device status.
- netstat: Display network connections, routing tables, interface statistics and other information to understand system network activities.
- ss: Displays socket statistics, faster than
netstat, and is used to view TCP and UDP port usage.
Comprehensive monitoring
- Monitorix: Open source system monitoring tool, providing visual display of system indicators (such as CPU, memory, disk I/O, etc.).
Choosing the right monitoring tool depends on your specific needs. The above tools can effectively monitor and manage CentOS Stream 8 systems.

How to measure thread performance in C?
Apr 28, 2025 pm 10:21 PM
Measuring thread performance in C can use the timing tools, performance analysis tools, and custom timers in the standard library. 1. Use the library to measure execution time. 2. Use gprof for performance analysis. The steps include adding the -pg option during compilation, running the program to generate a gmon.out file, and generating a performance report. 3. Use Valgrind's Callgrind module to perform more detailed analysis. The steps include running the program to generate the callgrind.out file and viewing the results using kcachegrind. 4. Custom timers can flexibly measure the execution time of a specific code segment. These methods help to fully understand thread performance and optimize code.
How to understand DMA operations in C?
Apr 28, 2025 pm 10:09 PM
DMA in C refers to DirectMemoryAccess, a direct memory access technology, allowing hardware devices to directly transmit data to memory without CPU intervention. 1) DMA operation is highly dependent on hardware devices and drivers, and the implementation method varies from system to system. 2) Direct access to memory may bring security risks, and the correctness and security of the code must be ensured. 3) DMA can improve performance, but improper use may lead to degradation of system performance. Through practice and learning, we can master the skills of using DMA and maximize its effectiveness in scenarios such as high-speed data transmission and real-time signal processing.
How to use the chrono library in C?
Apr 28, 2025 pm 10:18 PM
Using the chrono library in C can allow you to control time and time intervals more accurately. Let's explore the charm of this library. C's chrono library is part of the standard library, which provides a modern way to deal with time and time intervals. For programmers who have suffered from time.h and ctime, chrono is undoubtedly a boon. It not only improves the readability and maintainability of the code, but also provides higher accuracy and flexibility. Let's start with the basics. The chrono library mainly includes the following key components: std::chrono::system_clock: represents the system clock, used to obtain the current time. std::chron
How to use string streams in C?
Apr 28, 2025 pm 09:12 PM
The main steps and precautions for using string streams in C are as follows: 1. Create an output string stream and convert data, such as converting integers into strings. 2. Apply to serialization of complex data structures, such as converting vector into strings. 3. Pay attention to performance issues and avoid frequent use of string streams when processing large amounts of data. You can consider using the append method of std::string. 4. Pay attention to memory management and avoid frequent creation and destruction of string stream objects. You can reuse or use std::stringstream.
How to uninstall MySQL and clean residual files
Apr 29, 2025 pm 04:03 PM
To safely and thoroughly uninstall MySQL and clean all residual files, follow the following steps: 1. Stop MySQL service; 2. Uninstall MySQL packages; 3. Clean configuration files and data directories; 4. Verify that the uninstallation is thorough.
How to handle high DPI display in C?
Apr 28, 2025 pm 09:57 PM
Handling high DPI display in C can be achieved through the following steps: 1) Understand DPI and scaling, use the operating system API to obtain DPI information and adjust the graphics output; 2) Handle cross-platform compatibility, use cross-platform graphics libraries such as SDL or Qt; 3) Perform performance optimization, improve performance through cache, hardware acceleration, and dynamic adjustment of the details level; 4) Solve common problems, such as blurred text and interface elements are too small, and solve by correctly applying DPI scaling.
What is real-time operating system programming in C?
Apr 28, 2025 pm 10:15 PM
C performs well in real-time operating system (RTOS) programming, providing efficient execution efficiency and precise time management. 1) C Meet the needs of RTOS through direct operation of hardware resources and efficient memory management. 2) Using object-oriented features, C can design a flexible task scheduling system. 3) C supports efficient interrupt processing, but dynamic memory allocation and exception processing must be avoided to ensure real-time. 4) Template programming and inline functions help in performance optimization. 5) In practical applications, C can be used to implement an efficient logging system.
How to optimize code
Apr 28, 2025 pm 10:27 PM
C code optimization can be achieved through the following strategies: 1. Manually manage memory for optimization use; 2. Write code that complies with compiler optimization rules; 3. Select appropriate algorithms and data structures; 4. Use inline functions to reduce call overhead; 5. Apply template metaprogramming to optimize at compile time; 6. Avoid unnecessary copying, use moving semantics and reference parameters; 7. Use const correctly to help compiler optimization; 8. Select appropriate data structures, such as std::vector.
