7 款可替代 top 命令的工具!
大家好,我是杰哥,本文将为您介绍7款可替代 top 命令的工具,旨在让您更全面地掌握Linux操作系统中的性能监控手段。
首先,atop是scratch源码烧录一款基于C语言编写的全屏性能监视器,适用于Linux系统。它不仅能够记录进程、系统活动的每日日志,还能通过颜色显示过载的系统资源使用情况,提供包括CPU、内存、交换、磁盘、网络层等的系统级活动监控,并详细列出每个进程和线程的性能指标,如CPU利用率、apk源码代码内存增长、磁盘利用率、优先级、用户名、状态和退出代码等。atop结合内核模块netatop后,可进一步显示进程和线程的网络活动。安装atop需下载源码包,然后以root身份加载内核模块并启动守护程序。
其次,ctop是laravel源码教学一个基于Go语言编写的实时指标展示工具,专门用于查看容器的实时CPU、内存、网络、IO等指标。在遇到“dial unix /var/run/docker.sock”错误时,需要先通过官方安装脚本自动安装docker。安装完成后,执行ctop命令即可查看容器的实时指标。
iftop与top类似,专门用于监听命名接口上的网络流量,显示当前带宽使用情况。使用iftop时,只需提供接口名称即可。
iotop是一个用于识别消耗大量输入/输出请求的进程的工具,提供类似于top的性能监控,但关注的是进程的IO使用情况。iotop由Guillaume Chazarain的Python脚本启发,经过Vyacheslav Trushkin用C重写和Boian Bonev的改进后,无需Python即可运行。支持多种Linux发行版,包括Debian、Ubuntu、Fedora、CentOS、RHEL等。
nmon是一个用于AIX和Linux操作系统的性能监控工具,每两秒更新一次终端上的本地系统统计信息(CPU、内存、网络、磁盘、文件系统、NFS、进程、资源等),并以CSV格式保存统计数据,便于绘图和分析。若要处于记录模式,需在命令中添加参数选项。
slabtop用于实时显示内核“slab”缓冲区的详细信息。它提供选项进行排序,并显示内核缓存区的信息。
最后,virt-top是一个类似于top的实用程序,用于显示虚拟化域的统计信息,包括CPU、内存、虚拟磁盘、虚拟网络、虚拟机管理程序等。它需要使用libvirt才能显示不同虚拟化系统的统计信息,支持CentOS、RHEL、Debian、Ubuntu、Fedora、OpenSUSE等操作系统。安装virt-top的步骤在文中详细列出。
以上介绍的工具在Linux性能监控领域各有特色,根据具体需求选择合适的工具将能更深入地理解系统资源使用情况,优化系统性能。
