Network mapping tools provide IT teams with a visual map of every device in the enterprise, displaying each one’s status and logical connections. The agency also periodically scans the network and updates the representation accordingly. This allows IT staff to swiftly detect devices experiencing issues like excess traffic or downtime and instantly locate and resolve the primary cause.
Network issues – from a device outage to a problem with specific traffic – often arise in large and complex enterprise networks. Network mapping tools can help IT teams instantly identify the source of these issues, allowing them to resolve problems without hours of troubleshooting. A network mapping tool should provide a variety of alerting options. These include metrics and log alerts, which regularly evaluate a specific set of criteria. Metric alerts can be based on platform metrics, custom metrics, or logs converted to metrics. Metric alerts can also apply multiple conditions and dynamic thresholds. In addition to various alerting options, a good network mapper should be able to display network connectivity and dependencies in different views. Those looking for more advanced options should consider a tool that can perform network mapping and automated system monitoring.
Real-time Network Visualization
The human brain processes visual information much faster than textual data. For this reason, network visualization is a crucial tool for identifying connections between different pieces of corresponding data, allowing you to understand the bigger picture quickly. Visualizing data will enable you to find patterns and spot anomalies rapidly, making it a valuable asset for addressing security threats, reducing downtime, and troubleshooting performance issues. A network map visually represents your IT infrastructure, including servers, routers, and workstations. The map identifies the connections between each device, whether they are hardwired or describe data flows. Many maps also provide real-time insights into node status. Network mapping is a crucial feature of network visualization tools and can be created manually or automatically. Creating manual maps can be time-consuming and error-prone, especially when working with an extensive, complex network. A network visualization tool can make the process significantly more accessible and efficient, enabling you to identify connectivity issues in minutes.
Network admins need to know how their devices connect and interact. Without the help of network discovery tools, it may take them a long time to identify and resolve issues. This is especially true in large organizations with a wide range of wired, wireless, and cloud devices deployed across multiple sites and networks. Network device discovery software can scan the entire network and build a map of your topology. It can also create a list of all the connected devices and their status. You can then use this information to monitor and troubleshoot your network.
Additionally, the tool can provide detailed reports and graphs for the performance of the network devices. A network device discovery protocol works at Layer 2 to facilitate the exchange of information about a directly-connected network device, including its identity (e.g., device type/ID and port ID) with its neighbors. The information is then stored in management information bases (MIBs). Network device discovery solutions can use LLDP, SNMP, and ping to collect this data from network devices. Network device discovery tools can also be configured to prioritize the monitoring of devices based on their status. This allows network administrators to focus on the most critical devices and minimize the resources required for monitoring. They can also choose to ignore or approve a device during the discovery process or at a later point. They can even set up rediscovery rules for a specific IP range to automatically detect changes in the network topology and trigger appropriate actions.
Network maps are the basic foundation of any Network Monitoring and Management solution. They provide visibility into your network topology, including the layout of devices, mobile elements, and the dependencies between them that are required during troubleshooting and problem resolution. A quality network mapping tool will automatically update the map when there are changes in the network so that the information is always accurate. It will also provide different perspectives so you can look at the web from various angles and see the data most appropriate to your needs. Some of the best network mapping tools offer automated and manual map creation capabilities. Other network mapping options allow you to manually create a network diagram and provide a view showing all devices’ statuses. You can also edit, move, and resize widgets on the map to make it easier to understand how they relate.
Depending on the size of your network, you may use a software solution specializing in networking topology mapping. This type of tool helps you organize the layout of your network by showing all devices and their connections. This can help you plan a more efficient design for your system. It can also be helpful when implementing access control lists (ACLs) for network segmentation. In addition to visualizing your network, the best network mapping tools should allow you to inspect any device on a map. This will enable you to see detailed information about each device, such as its IP address and serial number. This can help monitor bandwidth usage and identify potential problems caused by overuse. Another essential feature of a network mapping tool is its ability to provide reports in various formats. These reports can be visual representations or statistics-focused and can be generated upon request or at regular intervals. The report format can vary based on your needs, and it is essential to consider which data will be most valuable to you. A good network mapping tool will also have a robust database of standard network devices. This can help you identify common devices that need to be replaced or upgraded. It can also help you determine whether a device is causing an issue with other devices on the network. This information can be precious for enterprises that draft bring-your-own-device (BYOD) policies.
