subject: Safety Practices And The Network Monitor Of Your System [print this page] A network monitoris a process that regularly monitors a computer network for problems, such as system failure, and notifies the network manager by way of email or other kinds of alarms. It detects any overloaded or crashed servers, network connections or other devices via the network monitorsystem. Most systems today have these types of devices to keep track of the network. Overseeing the network might include looking at HTTP pages, HTTPS, SNMP, FTP,SMTP,POP3,IMAP,DNS, SSH, TELNET, SSL, TCP, ping, SIP, UDP, Media Streaming and a range of other ports based on the system's schedule.
You can find metrics by which a computer network could be assessed.Response time, availability and uptime are the most common although some measure consistency and reliability.The current inclusion of WAN optimization devices has already impacted most network monitoring tools, particularly with measuring precise end to end response times due to the limit of round trip visibility. But with the current setup of the monitor network equipment, experts have discovered a way to lessen their effects and maximize the monitoring of the units.
Measurements which take care of the network monitor include network tomography and route analytics. Network tomography basically deals with examining the health of different links in a network using probes which go from end to end, dispatched by agents located at vantage areas in the network. At the same time, route analytics are methods, system, algorithms and tools which monitor the routing posture of networks.This is because incorrect routing causes undesirable performance degradation or downtime in the network. By effectively monitoring these variants, we can figure out the performance of the network.
Each time a system slows down or fails, the system must inform the network administrator of the incident.Notification might be made through an email message, pager alert, alarm or phone call. The network administrator should be notified of overloaded systems, failed servers, lost network connections, virus or malware attacks, and power failures. These notifications should take a high priority when it comes to the network administrator. Nonetheless, when it comes to power outages, it is vital that you note that your system needs to have back up power because if you lose power there it could affect the notification procedure.
The network monitoring system is normally made through a "ping", or a test to every computer in the network. Just in case the system will not respond or takes too long to do so, then there should be a notification to the network administrator concerning the problem. Pings are intended to be responded to right away. There are other monitoring network devices that take regular virtual shots of the network's workflow. In case there are irregularities in the workflow, the system will log it and if there is a significant threat to the network, a report ought to be made to the network administrator. Therefore, regular check ups ought to be scheduled to maintain the performance of your system.
