A server is a system of computers that provides network services. It is a collection of hardware and software facilities working together for the purpose of realizing effective communication among computers. Web server monitoring is carried out using web server software and it involves the software checking the working conditions of the server and sending messages to the checks on parameters such as the extent to which the CPU is used, performance level of the network in use and the disk space. It can have additional features such as alerting and benchmarking. The process of monitoring is divided into several categories as described below:
This is the process of having a close check on your firewall. Monitors such as PRTG may be employed to perform this task. It is equipped with a variety of sensors that undertake the process of firewall monitoring easily. One gets to know the exact activities going on in their internet in terms of data flow in and out of their system. The security of your system is highly boosted since any malware trying to get its way into your system is automatically detected and a warning message is sent to you. This monitoring system ensures that you are in control of your internet usage and indicates the top connections, top talkers and top protocols.
The bandwidth of a server system is monitored using a bandwidth monitoring software. It involves complete identification of the actual problems affecting a network system. This helps the administrators to start working on the problems from the go instead of continuously guessing what could have gone wrong. It keeps track of the information about the usage levels as far as leased lines are concerned. It is responsible for supervision of network connections, tracing the usage trends and measuring the bandwidth being used for billing purposes. This monitoring system is also involved in making decision concerning router traffic balancing and alerts the administrator in case of flaws in network load.
The fact that routers and WAN links form the most expensive components of a server system calls for effective monitoring to avoid incurring great losses. The act of monitoring routers help the administrators of the given server subscribe for enough bandwidth and avoid over-subscription that could lead to paying for more than necessary. This avoids possible congestion and other related network problems. Router monitoring helps in optimizing bandwidth allocations ensuring large network availability. It entails sporting a problem and initiating upgrades or even replacements if necessary. The administrator is made conversant with traffic trends hence the ability to plan for capacity and increment ROI as well as visualization and resolving WAN link flaws.
Protective switch monitoring system should always be put in place to avoid adverse effects of failures on LAN users. The system undertakes monitoring for port utilization and traffic with necessary alerts. The monitors here detect any potential storms on broadcast and prevent them. It notifies the administrator on the heavily used and underused ports. Data loss is taken care of by alerting the administrator whenever a port begins to discard. Switch port mappers are used to quickly supervise the status of the devices interfaced with the switch ports.
NetFlow monitoring and packet sniffing
NetFlow monitoring informs the administrators where their bandwidth is used, the person using it and the reason as to why the person is using it. This is important in that it shows you how the usage may affect you network. If it is potentially harmful then you can take the necessary corrective precautions depending on the nature of the danger. Its configuration involves setting a NetFlow sensor in PRTG and creating a new NetFlow sensor for each IP. Packet sniffing is used in a network to capture and record data flow. It allows for discerning every single packet and carrying out analysis on its predefined parameters. It is an addition to regular bandwidth capabilities. Their sensors make use of the host machine cards.
Network and VoIP monitoring
PRTG plays a very important role which is keeping the administrator informed before a failure or malfunction occurs in their network. This is useful as the administrator can take measure that prevents the flaws from happening hence reducing the cost of repair. Network monitoring increases the efficiency of a network through keeping track of bandwidth and data consumption. Network monitors are easy to install and use. They support remote control through notification techniques and multiple location monitoring. VoIP monitors constitute powerful QoS sensors that can measure jitter, the latency of a network and packet loss. With PRTG an administrator can be informed of his data usage on the instant and warned in case of quality deterioration.
