SERVER AVAILABILITY MONITORING AND METRICS2
Introduction
In the present era, network monitoring is all about carrying out proper effort which
is needed for detection of failing components of the network [9]. It is mainly inclusive of
large number of things like failing routers, problematic devices and required server. In
the present event of any kind of network monitoring is all about altering the user about
network administrator. Network monitoring is known to be a major components of
network management [4]. It comes up with huge number of challenges like the metrics
which should be taken into account for hardware, services and given application.
The coming section of the report is all about server availability tool that helps in
analysing the overall performance with respect to CPU monitoring, monitoring of
bandwidth and lastly overall availability. An evaluation is done with respect to detail of
server availability monitoring architecture. A solution has been providing with respect
avoiding data vulnerability in server availability. In the end, the overall impact of failure
prediction of server availability has been discussed.

Nagios Core: Nagios core is known to be a monitoring and altering engine which
serves as the main application that comprises of huge number of projects of Nagios. This
particular tool comes up extensible architecture that is completely designed for its
flexibility and scalability [3]. It comes up with huge API that comes up with set of
extended by making use of add ons. Nagios core comes up with huge number of duties
concerning check to schedule and even handling. Nagios core comes up with addons
which aims to provide some additional kind of benefits which is out-of-scope [12]. It is
mainly needed for carrying out list of function like performance graphing and distribution
monitoring.

Ganglia: It is known to be an open-source monitoring system which is needed for
high-performance system of cluster [8]. It is done is careful way for achieving low per-
node and high concurrency. Ganglia makes use of huge number of cluster in various
region of the world where it can scale to handle cluster with various kind of nodes [4].
Ganglia can be defined as a monitoring system which is easily scalable and helps in
having a complete view concerning metrics of Linux server and cluster in real-time.
