The Many Important Responsibilities Of A Network Monitor

You might need a network monitor to monitor network traffic as well as other variables

for the reason that a failure in the system may have grave consequences, such as the probable degradation of client relationships as well as the irrecoverable loss of data. A network manager or system officer (aka "sysadmin") is frequently in charge of monitoring network components to quickly detect failures or upcoming problems of network components, such as workstations, switches, servers, printers, and others. By adding a network monitor system, any uptime issue might be easily fixed by the administrator. More sophisticated software programs can even be utilized to supply a wide range of checks which will automatically alert the network manager should there is a failure with the vital network components.

The network monitor software is capable of doing this kind of checks through the application of TCP port checks, ICMP pings, SNMP, ARP, FTP, DNS, and HTTP protocol checks. This allows the manager to keep an eye on a wide range of network instruments and hosts since the system automatically transmits an email to the network managers if a server, printer, or other device fails. By means of this arrangement, IT professionals would be able to take action instantly and thus significantly lessen the down time.

The program for monitoring network conditions will also be valuable in uncovering malware, like computer viruses, Trojans, as well as adware. This could be performed regularly by looking into the condition of TCP ports which different programs often depend on to run on their network computers and servers. Thus, if the program finds that one of these ports is open, it's going to send the manager an e-mail or text message informing him of the occurrence. The sysadmin may also monitor network conditions to determine the processes that are being performed on remote computers to find out if there are any dangerous programs installed.

Such a monitoring application can also be utilized for reviewing the types of applications which are being run by the different end users. Thus, checks can be made to be certain that workers are not utilizing non-productive computer software (for instance media players and computer games) during work hours. A further possible application of monitoring software programs is that they could help monitor document sizes including the application logs and temp folders. By monitoring either the remaining free space or the dimensions of these data files and folders, you stand less risk of overcrowding the storage areas for computer systems and servers.

The computer software used to monitor network situations can also be used to check for any unauthorized users by keeping an eye on any MAC address modifications. This program can send a notification to the administrator as an email message, a warning sound, a text message to his cellular phone, the display of a particular message on the monitor, or the execution of certain JavaScript and Visual Basic scripts. It is also possible to program the reaction of the software package to certain occurrences by turning off or restarting a particular remote computer or service, or running certain external applications.
