Overview Of The Commercial Cloud Monitoring Essay

Question:

Discuss about the Overview Of The Commercial Cloud Monitoring.

Answer:

Introduction

The report is prepared after analysis of the three scenario and learning the principles of data communication and networks. Research is made on the different tools that can be applied in the organizational network for monitoring the data flow in the network and identification of the status of each of the computers connected in the network. The wireless access point installed in the network are also analyzed using the freeware tool for securing the network from illegal access. An analysis is made on the freeware tool that can be implemented in the network for evaluation of the performance by identification of the faults in the network and maintaining quality of service. The justification of the tool applied for each of the scenario is given with the screenshot of the tool interface that would help to understand the working of the tool used.

Tools’ features that are important for the scenarios

The features of the tools are described with the screenshots below:

The above screenshot is given for QoS Round Trip monitoring and an overview tab is selected for getting the detail of the network and values can be fetched from the overview. The reliability of the network can be gathered by implementation of the tool and measuring the round trip results. The different sensors available can be listed and selected for performing an operation and automated alert or notification can be set for alerting the network administrator in emergency situations.

The access of the core devices can restricted for some of the IP address using the PRTG freeware tool. It also acts as a firewall for the network and helps in securing the network from illegal activity.

The health of the server where the PRTG is installed can be fetched by analyzing the network adapter and generating the usage of the resource report. The screenshot below shows the health and status of the server.

The screenshot is given to analyze the protocols used by the nodes connected in the network for communicating with the neighbor nodes connected in the network. The device status can be fetched from group root option in the PRTG tool and the device can be categorized according to their similarity and the installed location in the network. The servers in the network are kept in different category than the nodes used for administrative purpose. This helps in easy management of the devices connected in the network.

The screenshots provides details about the sensors that can be used for generating alarm and the status of the alarm can be get as open, warning or uninstall. Three types of colour are used for demonstration of the severity of the alarm such as red is used for unavailable devices, yellow is used for warning and orange is used for the unusual behavior found in the network.

The PRTG network analysis tool can be used for generation of a report by using the sensors. The report consists of the details of the packets captured and the details such as protocols used for transmission of data in the network, bandwidth consumed and source, destination address. The network status is shown in percentage.

The map of the network of the organization is demonstrated in the above screenshot and it is used for evaluation of the current network infrastructure and the type of device installed in the network for the development of the network.

Justification of the tool choice

PRTG Network monitor tool is selected for monitoring the activities of the network and it matches the requirement for all of the three scenario and ensures the availability of the nodes and the other components in the network and measures the traffic usage in the network. The cost of the network can be saves by optimizing the connection between the nodes and avoiding the outrages in the network. The criteria used for the application of the freeware tool is evaluation of the tools available and the features provided by the tool to monitor the status of the entire network and identify the data flow in the network. There are different network monitoring tools available and the features are compared with each other for the selection of the best network monitoring tool and application in the network for management of the activities of the users. The PRTG can be installed in the central server of a network for analyzing the health of the server, throughput and the network traffic. It can also be used for analyzing the current drawn for each of the circuit. It can be used for creation of a group and more device can be added in the group and the auto discovery function of the tool helps in creation of an alert for grabbing the attention of the network administrator.

The PRTG can be installed in the central server and used for all the three scenario and monitor the activity in the network irrespective of the medium such as wired or wireless connection. For the wireless network its status should be maintained and the WiFi analyzer the freeware tool PRTG network monitor analyzes every aspects such as devices, availability, traffic, load and the signal strengths of the wireless network. SNMP sensors can be deployed in the network for monitoring the security instance of the network and it also uses packet sniffing and NetFlow for monitoring the wifi traffic. It supports Cisco as well as the Juniper routers and thus it is reliable for fast and easy wireless monitoring. It can be used as a central monitoring tool for the wireless access points installed at different location of a network and monitor the bandwidth and the devices connected in the network. The dashboard of the PRTG can be used for getting a quick overview and it comes with 200 predefined sensors that can save energy for monitoring the wireless network. If an abnormal activity is identified in the network the PRTG prompts an alert for the disruption and prevents the network from crashing.

For the third scenario the PRTG is an ideal solution because it can be used for the evaluation of the performance and QoS evaluation of the network. The PRTG provides real time monitoring of the bandwidth usage uses QoS round trip sensor for analyzing the data packets passing over the network. The QoS round trip sensor works by sending many UDP packets in the network and measures the result by analyzing the packets lost, packets duplicated, packets out order, packets corrupted, delay and jitter. This helps in building a network minimizing the errors in the network and increasing the quality of service.

Conclusion

For the selection of the freeware devices different available tools are analyzed according to the scenario and applied in the network for meeting the criteria. The use of the PRTG network analyzer helps in ident6ifiaction of the fault of the network and the security protocols used for the configuration of the devices. The data flow between the devices can also be identified for monitoring the performance of the network and maintaining the network quality. The network protocol analyzer can also be used for securing the wireless access points installed in different location of the network by analyzing the unauthorized access and using secure security mechanism for restricting the unauthorized users to access the wireless devices. There are different sensors available that is useful for the identification of the jitter and the loss of data packets in the network.
