在纯开源领域，分析如下：

Some of the most common open-source packages include:

• Big Brother: This product was popular before Nagios was released and stabilized. The product was introduced in 1996, and still retains much of its dated user interface and limited feature set. The product is still in use at some enterprises in pockets. Big Brother is not free for commercial use, but the original author created Xymon under an open-source license, which has an active community and development; however, the dated interface still exists. Quest Software acquired the rights to the commercial Big Brother product in 2001, and renamed the commercial offering Big Brother Professional, which has an improved interface and additional features.      开源监控软件
  
• MRTG, Cacti, Munin and Ganglia: These tools are graphing and polling engines, whose data is stored in a time series database (RRDtool). The core graphing and storage technology is a part of other open-source monitoring products, ranging from Centreon, Ntop, op5, OpenNMS, pfSense, SmokePing, Xymon, Zenoss and others. The polling is agentless (SNMP, WMI), but can leverage many APIs to poll additional hardware and software devices. MRTG, Cacti, Munin and Ganglia are not able to handle events, but there is a road map to correct this limitation in Cacti. Based on threshold settings, events may be dispatched to other event management systems (see [  /document/code/148506?ref=ddisp]"The Evolving Role of a Manager of Managers in IT Operations" [/url]), such as Nagios. Notification management is nonexistent in the products, so events must move to an upper-level management solution. MRTG, Cacti, Munin and Ganglia have hundreds of plug-ins available on the Internet, which enable monitoring of other software and hardware devices. MRTG, Cacti and Munin are generic polling engines, while Ganglia is geared toward large grid or large cluster monitoring. MRTG has been largely replaced by Cacti, but MRTG is still in use in many enterprises.     nagios实施
  
• Nagios: The most popular of the open-source monitoring solutions, Nagios, has been successful in its penetration into IT operations organizations of any size. Due to its widespread usage, it has spawned many enhanced commercial and open-source software packages, such as Centreon, GroundWork Monitor, Icinga, Nagios XI, op5 and Zabbix. The product was released in 1999, and due to its age, the open-source offering has a dated user interface, scalability issues due to much of it written in interpreted languages, and poorly optimized contributed plug-ins. The software can monitor agentlessly via SNMP and WMI, or can leverage agent technology. There are nearly 2,000 downloadable plug-ins available; most written in Perl and Python. There is a lack of robust event management or notification management, and there are plug-ins developed to provide additional options for both use cases.     nagios配置
  
• Ntop: This product takes a different approach to monitoring; it uses a packet capture engine or collects flow data via NetFlow or Internet Protocol Flow Information Export (IPFIX). When operating in packet capture mode, it's typically connected to a span or mirror port on the network. The product builds profiles of the systems on the network. It does not provide any alerting capabilities, but is used for diagnostics and debugging.nagios培训
  
• OpenNMS: The OpenNMS project is an open-source network-monitoring platform with capabilities around basic event management, polling network devices for configuration and performance data, and processing syslog log streams. Agentless polling and data collection is supported by using SNMP, HTTP, WMI, DNS and JDBC. The product scales well and provides good basic network monitoring capabilities, including discovery, event management and polling.    nagios安装
  
• Wireshark: This open-source packet capture and protocol analysis tool was previously called Ethereal, it is cross-platform and leverages the pcap capture library. It's intended for troubleshooting network behavior and understanding network-borne security issues. Data is captured from a network interface, or captured remotely and analyzed with the tool. Over 1,000 protocols can be decoded and analyzed. There is an active community, adding to the extensive feature list that includes tools for telephony analysis, such as voice over IP (VoIP), flow graphing and statistical analysis.    监控软件
