University Report: MN506 Server Availability Monitoring Assignment

This report provides a comparative analysis of various server availability monitoring tools, focusing on their capabilities in monitoring critical server metrics. The report examines nine different tools, including Nagios Core, Ganglia, Spiceworks, CollectD, Cacti, Icinga, Zabbix, OpenNMS, and WhatsUp Gold. Each tool is evaluated based on its ability to monitor CPU usage, disk usage, bandwidth, processes, and overall resource utilization. The report includes screenshots demonstrating the functionality of each tool in these areas. The analysis aims to identify the strengths and weaknesses of each tool, providing insights into their suitability for different server management scenarios. The report also touches upon the importance of server availability monitoring for organizations and the potential vulnerabilities that can arise from server unavailability. The report concludes with a brief evaluation and proposes recommendations for selecting the most appropriate monitoring tools.

2SYSTEM MANAGEMENT
Introduction:
Monitoring the availability of the servers is very much important concept for the
organizations as this is one of the core for their day to day operations. Though this is very
much important still the organizations faces various of issues as there is a metrics related
challenges which includes availability of the services, hardware and applications [1]. It is also
very much important for the organization to understand which operations requires which
resources and how much resource is required by those processes.
Thus in this paper various of server availability monitoring tools is leveraged to check
the performance in terms of CPU monitoring, Process Monitoring, Disk Usage, Resource
Monitoring, Bandwidth Monitoring and Overall availability. Also, the server availability
monitoring architecture and solution will be presented to avoid data vulnerability.
Comparison:
In this case nine types of server availability monitoring tools will be discussed which
are the following:
 Nagios Core
 Ganglia
 CollectD
 Spiceworks
 Cacti
 Zabbbix
 Icinga
 OpenNMS
 WhatsUp Gold
(1) Nagios Core:
This is an open serving checking tool. This tool is connected with the entire server for
the monitoring purpose.

The above image shows CPU monitoring of the system through Nagios Core.
(2) Ganglia:
Ganglia is also an observing programming of the server. Various levelled plan has
been utilised in this case [7].

Bandwidth monitoring has been shown in the above screenshot. Two services has
been selected in this case.

(3) Spiceworks:
Spiceworks is used for knowledge identification of the servers, switches, and the
SNMP gadgets. This also used for discovering the IP addresses of gadgets [3].
(Figure 9: Disk usage of Spiceworks)

Disk usage has been shown through above screenshot. From the screenshot it has
been seen that system disk is 86% free, C drive is 81% free and F drive 74% free.

Disk activity has been shown on the above screenshot by using the Spiceworks. The
graph shows data transfer speed from the disk for a particular process.

Active processes involved with the system has been shown in the above screenshot
of the Spiceworks software.

includes the response time of the system.
(4) CollectD:
CollectD is an open source type of instrument for the server observing. RRD records
can be gathered using this tool [6].
