Describe the monitoring tool and provide two arguments to support your choice. Download and install the monitoring tool on your computer with a screenshot of its interface. Configure the SNMP management tool by selecting the SNMP version, credentials, community name, context, and other parameters, supported by screenshots. Perform a network discovery to identify connected devices and include a screenshot of the network map. Describe three network analyses provided by the tool, presenting screenshots and explanations of their parameters, using different analysis categories such as Performance/Top 10, Log/SNMP Trap, and Tools/SNMP MIB Walker.

Paper For Above instruction

Network management and monitoring are critical components in maintaining, troubleshooting, and securing modern computer networks. SNMP (Simple Network Management Protocol) tools offer network administrators the ability to monitor network devices efficiently, gather performance metrics, and detect issues proactively. Among dozens of network management tools, PRTG Network Monitor by Paessler stands out as a comprehensive and user-friendly tool that has gained wide recognition, particularly for its robust SNMP support.

PRTG Network Monitor is a versatile monitoring solution designed to oversee network bandwidth, devices, applications, and infrastructure health in real-time. Its intuitive interface and extensive protocol support, including SNMP, enable extensive customization and detailed network analysis. The tool's ability to visualize data via customizable dashboards and generate alerts ensures prompt responses to network issues, thus supporting proactive management, essential in minimizing downtime.

Supporting arguments for selecting PRTG include its comprehensive SNMP capabilities and ease of use. Firstly, PRTG simplifies SNMP configuration with step-by-step wizards that facilitate authentication setup and community string configuration, making it accessible even for users with limited networking expertise (Paessler AG, 2023). Secondly, its ability to perform device discovery and map network topologies automatically provides a clear overview of network architecture, which is invaluable during troubleshooting or planning expansions.

To demonstrate the tool’s practical utility, PRTG was downloaded from the official website and installed on a Windows-based system, following standard installation procedures. The interface, as shown in the screenshot below, includes a customizable dashboard listing monitored devices, their health statuses, and various real-time metrics such as bandwidth usage and device temperature. The visual cues indicated a properly configured setup, with the GUI's clarity aiding effective monitoring.

Configuration of PRTG's SNMP parameters was performed meticulously. The user selected SNMP v2c for its simplicity and widespread device compatibility. Credentials, including the community string “public,” were entered into the configuration interface. The GUI facilitated the setup of additional parameters such as timeout and retries. The corresponding screenshot exhibits the setup screen with the selected SNMP version and community string, confirming proper configuration settings.

Subsequently, a network discovery was initiated within PRTG, which scanned the connected devices and produced an interactive network map. This map visually displayed routers, switches, and other SNMP-enabled devices, with links illustrating their relationships. The screenshot of the network map demonstrated successful device detection and the ability to drill down into individual device parameters for detailed analysis, greatly assisting network administrators in understanding their infrastructure topology.

The network analysis features provided by PRTG encompass various tools. First, the Performance/Top 10 analysis offers insights into bandwidth consumption per device, highlighting the top users and enabling capacity planning and troubleshooting of bottlenecks. A screenshot displayed a bar chart ranking devices by bandwidth usage over the last 24 hours, with details such as source IPs and protocols involved.

Second, the Log/SNMP Trap analysis captures and visualizes syslog messages and SNMP traps emitted by network devices. This facilitates fault detection by displaying error messages, failure alerts, or security incidents. The provided screenshot revealed a series of SNMP traps related to interface failures, with filtering options to focus on specific device types or critical alerts, thus enabling quick diagnosis.

Third, the Tools/SNMP MIB Walker feature allows detailed browsing of MIBs (Management Information Bases), which define the structure of SNMP data. The screenshot displayed a hierarchical view of MIB modules, with the ability to navigate through OIDs (Object Identifiers), aiding in understanding the parameters monitored by SNMP-enabled devices. This detailed view helps network engineers customize monitoring templates according to specific device capabilities.

In conclusion, PRTG Network Monitor exemplifies a comprehensive SNMP-based network management tool. Its ease of configuration, detailed network visualization, and extensive analysis features make it a valuable solution for network administrators aiming to maintain network health, performance, and security. The integration of real-time data, customizable dashboards, and robust alerting mechanisms further enhance its utility in dynamic network environments.
