Netsaint is a network monitoring tool that helps system administrators understand the operation status of the device and system running status. Netsaint (http://www.netsaint.org) is a free, open source network monitor. The NetSaint Network Monitor is composed of a host and a network monitoring package configured with alert mechanism, including email and paging support. The monitor is written in a C language on the Linux platform, which is easy to transplant to other operational platforms. There is a graphical interface script to integrate NetSAint to the web server to facilitate query status and historical information on the Web. Currently, you can download the NetSaint 0.0.7 version of the beta 4 for free. Once installed, NetsAint runs as a background process on the monitor. The most important job in execution is to determine what to monitor, when alarms have a alarm, and how to convert the alarm information into a configuration file. The installation process is actually an installation profile, there is a specific configuration command in the guide operation, and options. The NetSAint configuration file has strong flexibility, defining host groups, router groups, switches, etc., and can set different rules to different monitoring objects, just like the entities that can be divided into individuals. In the alarm function, the time period can be specified, give different time division methods, allowing NetSAint software to send the desired information in the specified time. In addition, NetsAint can monitor system idle hard disk space and CPU usage - although Solaris can do this, NetsAint can run automatically, automatically analyze results, and compare it with a threshold. If the threshold is exceeded, the alert is triggered. In addition, NetsAint also provides some additional features, such as automatic log file changes, automatically trigger event processors when the alarm occurs. Netsaint is better than UNIX is its powerful monitoring. It can be connected to a given port to respond to a response signal; can connect the network with the ping command, and make mail operations with SMTP. If you use a plugin, more complex monitoring can be performed. Downloading websites in the Netsaint Downloaders can download various NetsAint plugins and additional kits. Netsaint software has a powerful feature to make the network administrator can always understand the system and allow the system under its control. Netsaint is not a capacity planning tool, which does not replace BST-1 programs such as BMC, when it tracks system trends, only simply record changes in state rather than record system running characteristics. It shows that the disk space triggered the frequency of the alert in the previous period, not how much disk space actually in the past a time period is used. This limits Netsaint instead of commercial monitor tools, such as the Unicenter of Patrol and CA of BMC. For the net administrator, if you need to monitor your network anytime, anywhere, Netsaint is a good choice.
A variety of third-party NetSAint configuration applications are available, they make the server's management easier. The most popular in these applications is NEAT (Netsaint Easy Administrator Tool), Neat can download page at Netsaint, http://www.netsaint.org/downloade
