Introduction
One of the core issues which many companies face in day to day operation is the monitoring
availability of services and server. In addition, there are problems which the company also faces
which includes what metrics the availability of hardware, application, and services should be
considered. Also, it is very crucial to understand the resources which services and the server will
require in an order running it smoothly and thus the company’s operations will run smoothly. In
our discussion, we shall mainly focus on comparing various server availability monitoring tools,
evaluating server availability monitoring architecture, propose a solution to avoid data
vulnerability in the server availability monitoring tools and effects of failure prediction on server
availability monitoring.
Comparison of various server availability monitoring tools
Nagios is one of the leading tools for monitoring, its disks usages are more than 2GB. In
addition, this tools has the capacity of monitoring all component in the system such as OS,
system metrics, applications, websites, and network protocol, its bandwidth monitoring is high.
Moreover, Nagios usually run on 4 core monitoring engines which give the high performance to
the system using fewer resources. As stated by Renita [5] The overall availability of the Nagios
is improved since it can allow over million users to use and also it can allow access to multi-
users.
Zabbix is a monitoring tool which is highly designed to monitors everything in the system which
includes the availability of the server, database, network equipment to network application and
the system performances. It disk usages is approximately 1.9GB and bandwidth monitoring is

high. This tool is readily available since it is used by many companies in the worlds such as
Orange and DELL. In addition, Zabbix is also term as server agent architecture which the user
can install the agent on the server for the Zabbix server to monitor it.
Cacti is a monitoring tool which is open source, which is usually installed on Windows OS or
Linux. It has disk usage of around 1.5 GB and has high bandwidth monitoring. This tool is
connected to RRDTool will allow users to generate graphs for network data. It closely works
with SNMP and it gives out network statistics in the form of charts that user can easily
understand thus it is readily available.
OpenNMS is another tool for monitoring server and networks and this tools data can be collected
using metrics which includes XML HTTP, JDBC, XML, and JSON. This tools can be used to
discover the two layers network of topology thus CPU monitoring is high. In addition, this tool
supports grafana and it is building in event-driven architecture. The monitoring process of
OpenNMS is very simple since its report can be view in the dashboard and charts. It is disk
usage is approximately 1.7GB and bandwidth monitoring is moderate.
Icinga is monitoring a tool that allows the user to monitor all the available systems in the
network, which can alert the user if there is an alarm to secure database in the system. In terms of
CPU monitoring, these tools are faster, scalable and easily configured. For instance, Kim says [7]
Its disk usage is around 1.4GB and bandwidth monitoring is slightly high. Generally, this tool is
readily available and thus it requires high CPU monitoring as elaborated in [6].
WhatsUp Gold is up and down monitoring tool, which can be used in alerting the system, and be
configured to submit alerts via email or SMS when the server experience a problem. In addition
to WhatsUp Gold monitoring devices, it can also monitor processes and services. Its disk usage
