The deployment and use of Internet/Intranet are growing rapidly, leading to a significant change in the computing mode of enterprises and consumers. The market has put forward the demand for traffic statistics and management technology, and requires this technology to effectively provide the information necessary to record the utilization of network and application resources. To this end, Cisco Systems introduced a new exchange technology, NetFlow exc

In this era of rapid development of Internet-based e-commerce, it is a challenging task to gain a firm foothold in the fierce competition environment. Therefore, service providers and enterprises must pay close attention to the latest development of Internet-related technologies. We have noticed that Cisco's IOS switching architecture has recently introduced two new technologies: Cisco fast forward transmission CEF) and network data flow NetFlow) serv
The deployment and use of internet/intranet is growing rapidly, and has led to a major shift in business and consumer computing patterns. The market has put forward the demand for traffic statistics and management technology, and requires that this technology can effectively provide the information needed to record the network and apply the resource utilization.

NetFlow is a network protocol that collects IP traffic information as records and sends them to collectors such as CA NetQoS for traffic analysis. Vmware vSphere 5 supports NetFlow v5, the most common version supported by network devices. The NetFlow feature on the vSphere 5 platform provides visibility into virtual infrastructure traffic, including:

Introduction of Nagios
Nagios is an open source computer system and network monitoring tool, can effectively monitor Windows, Linux and UNIX host State, switch routers and other network settings, printers and so on. When the system or service status is abnormal, send an email or SMS alert the first time to notify the site operators, in the state of recovery after the normal mail or SMS notification.
