【Linux性能实时监测工具-Netdata】

Linux性能实时监测工具-Netdata,它是Linux系统实时性能监测工具,以web的可视化方式展示系统及应用程序的实时运行状态(包括cpu、内存、硬盘输入/输出、网络等linux性能的数据)。Netdata的web前端响应很快,而且不需要Flash插件。 UI很整洁,保持着 Netdata 应有的特性。第一眼看上去,你能够看到很多图表,幸运的是绝大多数常用的图表数据(像 CPU,RAM,网络和硬盘)都在顶部。如果你想深入了解图形化数据,你只需要下滑滚动条,或者点击在右边菜单的项目。通过每个图表的右下方的按钮,Netdata还能控制图表的显示,重置,缩放

Netdata用可视化的手段,将被监测者最细微的细节,展现了出来。这样便可以清晰地了解linux系统和应用程序此时的状况

优美的界面:bootstrap框架下的控制界面

自定义的控制界面:你可以使用简单的HTML代码去自定义控制界面(不需要使用javascript)

极其的快速而高效:程序使用C进行编写(默认安装下,预计只有2%的单核CPU使用率和少许的内存使用率)

零配置:你只需要去安装它,接着它就会自动地监测一切数据

零依赖:它的静态网络文件和网络接口拥有自己的网络服务器

可扩展:用它自身的插件API(可以使用许多方式来制作它的插件,从bash到node.js),你可以检测任何可以衡量的数据。

可嵌入:它可以在任何Linux内核可以运行的地方运行



 

监测内容:下面是Netdata目前检测的内容(大多数都不需要进行配置,安装后即可开始监测)

1.CPU的使用率,中断,软中断和频率(总量和每个单核)

2.RAM,互换和内核内存的使用率(包括KSM和内核内存deduper)

3.硬盘输入/输出(每个硬盘的带宽,操作,整理,利用等)

4.IPv4网络(数据包,错误,分片):

TCP:连接,数据包,错误,握手

UDP:数据包,错误

广播:带宽,数据包

组播:带宽,数据包

5.Netfilter/iptables Linux防火墙(连接,连接跟踪事件,错误等)

6.进程(运行,受阻,分叉,活动等)

7.NFS文件服务器,v2,v3,v4(输入/输出,缓存,预读,RPC调用)

8.网络服务质量(唯一一个可实时可视化网络状况的工具)

9.应用程序,通过对进程树进行分组(CPU,内存,硬盘读取,硬盘写入,交换,线程,管道,套接字等)

10.Apache Web服务器状态(v2.2, v2.4)

11.Nginx Web服务器状态

12.Mysql数据库(多台服务器,单个显示:带宽,查询/s, 处理者,锁,问题,临时操作,连接,二进制日志,线程,innodb引擎等)

13.ISC Bind域名服务器(多个服务器,单个显示:客户,请求,查询,更新,失败等)

14.Postfix邮件服务器的消息队列(条目,大小)

15.Squid代理服务器(客户带宽和请求,服务带宽和请求)

16.硬件传感器(温度,电压,风扇,电源,湿度等)

17.NUT UPSes(负载,充电,电池电压,温度,使用指标,输出指标)

可以监测任意数量的SNMP服务,不过你需要进行配置,还可以对此软件进行扩展,可以使用任何语言编写插件,以此来从任何来源收集数据



 

What does it monitor?

netdata collects several thousands of metrics per device. All these metrics are collected and visualized in real-time.

Almost all metrics are auto-detected, without any configuration.

This is a list of what it currently monitors:

  • CPU
    usage, interrupts, softirqs, frequency, total and per core, CPU states

  • Memory
    RAM, swap and kernel memory usage, KSM (Kernel Samepage Merging), NUMA

  • Disks
    per disk: I/O, operations, backlog, utilization, space, software RAID (md)

  • Network interfaces
    per interface: bandwidth, packets, errors, drops
  • IPv4 networking
    bandwidth, packets, errors, fragments, tcp: connections, packets, errors, handshake, udp: packets, errors, broadcast: bandwidth, packets, multicast: bandwidth, packets

  • IPv6 networking
    bandwidth, packets, errors, fragments, ECT, udp: packets, errors, udplite: packets, errors, broadcast: bandwidth, multicast: bandwidth, packets, icmp: messages, errors, echos, router, neighbor, MLDv2, group membership, break down by type

  • Interprocess Communication - IPC
    such as semaphores and semaphores arrays
