Understanding Network Monitoring Network is group of multiple systems which are linked together. These systems need to carefully monitored and their performance analyzed to ensure that they are working to their maximum efficiency. Also, in case of any trouble, the network administrator should be informed in the fastest possible way to minimize the damage. This all is done through network monitoring. Network monitoring is a part of Network Management. Like an Intrusion Detection system tries to detect threats from the outside, the network monitoring system supervises the complete network for problems which may be due to overloading, crashed servers, problems in network connections or any other device. For example, if the status of the web server is to be determined, the monitoring software will send an HTTP request for a page periodically; for an email server, test message is sent using SMTP and is recovered using IMAP or POP3. The performance of the system is usually measured in terms of response time and the availability, also known as uptime, though measurement in terms of consistency and reliability is also gaining popularity. Wan optimization devices limit the round trip visibility and hence have an undesirable effect on the network monitoring tools especially when accurate measurement of response time is required. When the request fails, like when the connection is broken or cannot be established, time-out occurs and the desired data, message or document cannot be retrieved and this triggers the monitoring system into action. These actions vary from fault to fault and upon the design of the network monitoring system. Though all the system notifies the resident or the supervisor in the appropriate manner and a failover system is activated automatically to isolate the problematic server till it is repaired. Performance of Network Uplink is done through network traffic measurement. Monitoring services for a website can check the HTTP pages, HTTPS, FTP, SNMP, POP3, SMTP, IMAP, TELNET, SSH, SSL, DNS, ping, TCP and through a variety of other ports with check intervals varying over the wide range. Most services though check the server regularly at time period varying from one minute to an hour. Monitoring services generally have large number of serves throughout the globe, like in Asia, Australia, Europe and America. By having this huge number of servers in different locations, monitoring service can know if any web server is present throughout different networks in the world. More the number of locations, clearer is the idea on your websites accessibility.
