What is the best tool for monitoring network bandwidth usage?

An example I have seen is the Wireshark: A powerful network protocol analyzer that allows you to capture and interactively browse the traffic running on a computer network.

Monitoring network bandwidth usage is crucial for several reasons. Firstly, it helps in identifying potential bottlenecks or congestion points within the network, allowing for proactive management to ensure optimal performance and prevent downtime. Secondly, it aids in detecting and addressing any unauthorized or excessive use of network resources, which can lead to security risks or increased costs. Additionally, monitoring bandwidth usage provides valuable insights into traffic patterns and trends, enabling better capacity planning and resource allocation for future network upgrades or expansions. Overall, effective monitoring of network bandwidth usage is essential for maintaining network reliability, security, and efficiency.

There are several tools to monitor network bandwidth usage. The network bandwidth monitoring provides real-time insights into usage across your network so you can proactively manage any bandwidth limits but it also helps identify bandwidth hogs on your network which could point to other issues such as a network intrusion.

Cacti is also the best tool to monitor bandwidths. In Cacti we can see current utilisation, average utilisation for particular time frames. Even we can see minimum and maximum utilisation as well. Also we can download that data in a CSV file.

AWS CloudWatch Choosing the right type of network bandwidth monitoring tool depends on factors such as the size and complexity of the network, monitoring requirements, budget constraints, and existing infrastructure.

Network bandwidth monitoring tools come in various types, catering to different needs and environments. Passive monitoring tools, such as packet sniffers or network traffic analyzers, capture and analyze network packets to provide detailed insights into bandwidth usage and traffic patterns without actively participating in network operations. Active monitoring tools, like network performance testing software or bandwidth testers, generate artificial traffic to assess network performance and bandwidth availability in real-time. SNMP-based tools leverage Simple Network Management Protocol to collect and monitor bandwidth usage data from network devices such as routers, switches, and servers, offering centralized visibility and management.

iPerf3 works well for measuring bandwidth from one location to another. Cisco routers also have some SLA tools that can provide insight into latency, delay, and the like. Wireshark can be used to that as well. PRTG is a good freeware SNMP/Netflow monitor but most any SNMP manager can graph bandwidth usage. Netflow - via collectors - can provide more detailed information, including the type of traffic and the sender/receiver.

Network bandwidth monitoring tools typically offer a range of features including real-time monitoring of bandwidth usage, historical data analysis for trend identification, customizable alerts for abnormal usage or performance issues, detailed reporting for capacity planning and compliance purposes, support for multiple network device types and protocols, integration with other network management systems, and scalability to accommodate networks of varying sizes and complexities. Additionally, some tools may provide advanced features like deep packet inspection, application performance monitoring, traffic prioritization, and cloud-based deployment options to meet diverse monitoring requirements.

You can configure them to provide you real-time alerting and searching the graph for previous data. That helps analyze time to time change within the traffic/bandwidth.

Usage Tracking: They measure how much data is being sent and received over your network to identify how much bandwidth is being used. Performance Alerts: They notify you when bandwidth usage is high or if there's unusual network activity, helping prevent slowdowns or outages. Detailed Reports: They provide reports and graphs showing bandwidth trends over time, helping you understand your network's usage patterns. Traffic Analysis: They analyze which applications or devices are using the most bandwidth, helping you manage and optimize network performance. Real-Time Monitoring: They offer a live view of network activity, allowing you to see what's happening on your network at any moment.

Each tool has its strengths, so the best choice depends on your specific needs, like how detailed you want the bandwidth information to be and how easy the tool is to use.

To choose the best network bandwidth monitoring tool, consider your specific needs: the size and complexity of your network, required features (detailed reports, real-time alerts, etc.), ease of use and deployment, available budget, and compatibility with your existing infrastructure. Compare features and user reviews to select the tool that best fits your requirements, keeping in mind flexibility to adapt to future network developments.

It depends on what level of the visibility you're looking for from the monitoring tool. For example, link level vs traffic flow level.

NetFlow Analyzer leverages on?Cisco NBAR?to give you deep visibility into layer 7 traffic and recognize applications that use dynamic port numbers or hide behind well-known ports. ManageEngine netflow analyser is best tool for traffic analysis and bandwidth monitoring tool.

There are a number of network bandwidth monitoring tools, with their ease of use ranging from easy to use to moderately complex. Examples of these are Wireshark, Glasswire, PRGT, NetFlow, and IPFIX.

I have experience using various network monitoring tools such as PRGT, Nagios, and NARF. However, I found NARF to be exceptionally useful, especially when integrated with the AWS platform. NARF's user-friendly interface and device categorization feature have made network management a seamless process. The ability to categorize devices into different groups has greatly simplified network monitoring and troubleshooting tasks. Overall, NARF's integration with AWS has enhanced the monitoring and management of network devices, making it a preferred choice for network engineers.

There are a few different tools that can be used to monitor network bandwidth usage, but one of the most popular is PRTG Network Monitor. It's a comprehensive network monitoring solution that offers a wide range of features, including real-time bandwidth monitoring. It can also track a wide range of other metrics, such as CPU usage, memory usage, and network traffic. In addition to bandwidth monitoring, it can be used to monitor the health and performance of servers, storage devices, and other network components. There are a few good alternatives to PRTG, including Nagios and SolarWinds. Nagios is a free and open-source monitoring solution that's highly customizable.

When we talk about monitoring bandwidth usage, we always need to consider the purpose of the network, whether it's a business network or a SOHO/home network. The first step is to identify which protocols and connections consume the most bandwidth and whether they are essential or related to the network's use. The next step is to determine who is generating this traffic and again, whether it is related to or essential for the network's purpose. Most business equipment manufacturers have tools to limit bandwidth by port or by a specific IP or subnet. So, the important thing is to determine who needs what and when.

Unabh?ngig vom Einsatz von Tools k?nnen regelm??ige Befragungen der Nutzer bzgl. ihres subjektiven Empfindens der Netzwerkperformance sinnvoll sein. Dabei spielen dann selbstverst?ndlich noch andere Faktoren mit als das Netzwerk, aber dafür bekommt man auch ein Feedback, ob sich die Theorie anhand der reinen Messwerte so auch in der Praxis widerspiegelt.

Cost is something that should be considered while planning to implement Network Bandwidth Monitoring tools. There are open source as well as paid tools available in the market. just select on that fits in requirements and budget.
