Introduction
The term server monitoring is defined as a process which is involved in the field of
information technology for reviewing and analysing a computer server for
performance and availability. Information technology monitoring tools and techniques
have been available for a long time and it is very important for companies to monitor
the availability of servers [1]. The aim of this report is to examine various kinds of
server monitoring tools and critically evaluate the server availability monitoring
architecture. In this modern era, it is very important for controlling and monitoring the
availability of servers which can help companies for improving their performance.
mainly, this report is divided into several sections, for example, comparison between
types of server availability monitoring tools, evaluate the server monitoring
architecture, the solution to avoid data vulnerability and impact of failure prediction
on the server monitoring system.
Comparison between server availability monitoring tools
Nagios core
It is one of the best kinds of monitoring tools that provide a platform to the
organization for determining and addressing the IT infrastructure issues liked with the
computer networks. such kind of monitoring tool uses host resources as a disk and it
has the potential for monitoring the computer servers in an effective manner [2]. As
compare to the other server monitoring tools nagios core is more effective and can be
used for CPU monitoring in companies. Mainly, it is designed for companies where it
provides large flexibility, scalability to the employees and consumers. However,
Nagios XI delivers an updated web interface system which increases the performance
of computer servers.
Ganglia
It is another type of monitoring tool which is mainly used for monitoring the process
and bandwidth of networks. Moreover, it has the ability to controlling and managing
various systems, for example, grids and clusters and use XML process for data
representation [3]. As compared to the other monitoring tools it is very reliable and
can be used in business industries but it requires more efforts rather than Nagios
monitoring tool. Such kind of process is a part of an open source monitoring system
that has the potential for comparing hosts across the computer networks. Moreover,
such kind of server monitoring tool allows checking single metrics on numbers of hosts
which support networks servers for improving performance of the system.
