• The principle job of network monitoring software is to
oversee the functioning of servers, workstations, and other
devices connected to a network. This software is used to
ensure availability and overall performance of network
services, as well as to help find correlation when an event
1. Important Features of Network Management Tools
• Networking tools continuously scan devices and connections on a
computer network and immediately notify a network administrator about
latency or irresponsive or failing devices failures that may lead to a
slowdown or complete shutdown of the system.
• In simpler words, network monitoring is spying for a good cause. You want
at least one system to keep an eye on other devices to ensure that
everything is moving smoothly..
• The software primarily measures the central processing unit (CPU)
utilization rate along with the network bandwidth utilization rate.
Bandwidth refers to the data carrying capacity of the connection.
• Usually expressed in bits per second (bps), it is the data transfer rate
supported by a network connection or interface. The greater the
bandwidth, the higher will be the data rate supported by the device.
• This software sends messages called watchdog messages over the
network to ensure that everything is working smoothly and according to
the plan. If the message fails to elicit the desired response, it sends an
alert to system administrators through mobile, phone, e-mail, etc.
2. Tools Involved in Network Monitoring
• The most important and widely prevalent network monitoring tool is a
program called Ping. Ping is a software program that is commonly used to
test computers making use of Internet Protocol (IP) to exchange messages
• This test is most commonly used to determine internet accessibility. This
tool sends a message over a packet switching network to the specified
address and waits for a response.
• Anyone on the computer network can make use of the ping request to
verify if the internet connection is working and also to measure the
current connection performance.
• Ping though a useful testing tool for internet connection is unsuitable for
adequate monitoring of larger computer networks. Sophisticated
networking tools like LANDesk are used by professional administrators of
larger networks to monitor the availability of net connection .
You could mention SNMP as well.
3. Server Monitoring Tools and Software
• Server monitoring software is used for monitoring performance metrics
like CPU usage rate, network utilization rate, memory usage, data
processing, and so forth.
• The analysis of these critical metrics in real time prevents downtime and
keep mission critical applications running smoothly, without a hitch.
• Some of the important functions performed by this server monitoring
tools are as following:
4. Monitoring of Memory Utilization
• This aspect relates to the monitoring of critical memory usage metrics
along with gaining the knowledge of the memory used and the free
memory of the device connected in the network.
• Quality server software provides color graphs for easy understanding of
memory usage and pattern. This enables the server administrators to
easily deal with capacity planning and other issues related to memory
5. Disk Usage Monitoring
• Logic Monitor’s disk monitoring tool captures and analyzes disk usage
metrics like disk utilization, individual disk utilization, disk
input/output, and others to assist administrators in maximum effective
utilization of disk capacity.
