Network MonitoringWhy is network monitoring needed?A system that detects any kind of problem caused to the network due to crashed and overloaded servers, network connections or any other device is called network monitoring. A network monitoring software periodically sends messages over the network to ensure that the host is responsive. When the host fails to respond or is slow it quickly sends alert messages to designated locations so that the system administrators are notified. Most of the network monitoring tools is adversely affected by the addition of WAN optimization. This is caused due to the attempt in order to measure accurate, end-to-end response time. Network monitoring tools may use over 50 types of parameter-based checks to monitor the performance of your network. Devices using any TCP Port like FTP, HTTP, HTTPS, POP3, NNTP, VNC, SMTP, DNS, and many more can tracked using such tools. You can also use such tools in databases like ODBC, MySQL or Oracle. In some network monitoring tools you can send SMS back to the software as well. You can also perform checking SNMP values like free memory, disk space, CPU usage, etc. The system helps in overseeing how a computer network works using certain management tools. The network monitoring systems ensure availability and proper functioning of computers and network services. Which are the network monitoring tools?The ‘ping’ program is the most popular network monitoring program. It sends internet protocol (IP) messages between two hosts. This helps in measuring current connection performance between the two. The ‘HP Openview’ and the ‘LANDesk’ are the two packages which are more sophisticated as compared to the ‘ping’. They are used by professional administrators on larger computer networks. How is network traffic captured with network monitor?Network monitor is a network diagnostic tool that displays network statistics graphically. The network administrators use this information and perform tasks related to troubleshooting. The network monitor collects the following information by the process of capturing:
A network card supporting promiscuous mode is needed by your computer to make use of the monitor. Monitoring Network PerformanceA work environment demands proper communication across a network. Optimization of you system’s performance by network performance analysis like monitoring network traffic and resource utilization is very important. How does network bandwidth monitor work?A network bandwidth monitor:
The network bandwidth monitor helps you view the traffic flow of your network connections, LAN or WAN in real time using bandwidth monitor. The software is fully compatible with any kind of network connection. Multiple networks monitoring at a time is also possible using this. When the internet and LAN connections network traffic on one computer need to be monitored then the network bandwidth monitoring finds its use. In this way traffic rates of all network connections on your computer can be monitored. |
