The process of tracking network traffic and bandwidth by analysing flows based on various technologies is referred to asnetwork traffic monitoring or NetFlow monitoring. One requires whole visibility to comprehend transmission and network behaviour better. Tools for monitoring network traffic offer visibility together with statistics on trends and peaks.
Monitoring network bandwidth
Monitoring network bandwidth is keeping track of and evaluating the amount of data that moves via a network. It assists in locating potential bottlenecks and disruptions by measuring the real bandwidth available over a LAN or WAN. It’s critical to assess a network’s bandwidth metrics at the device and interface levels. Using diverse technologies including NetFlow, sFlow, and J-Traffic,LogicVein analyses flow. You may get total visibility into the network bandwidth with statistics on peak traffic, top applications, and top discussions. Use the network bandwidth monitoring software from LogicVein to locate bandwidth wasters, eliminate them, and improve the performance of your network.
Advantages of network traffic analysis
The main source of traffic this decade has been machine-to-machine traffic. A network monitoring tool is necessary for network administrators to keep a watch on their networks. You should also keep tabs on how much traffic is using your network. Additionally, management might be interested in learning about any bandwidth wasters, intrusions, lags, or unauthorised access.
A network traffic monitoring tool can be used to:
During peaks, a port is overloaded with unfinished operations, a lot of incoming traffic from a specific application, etc.
Obtain thorough statistics and reports that you may utilise to solve these problems fast.
Determine the data centre scenario’s traffic generation location.
Monitor the flow of people between the main office and the outlying offices.
Utilize LogicVein On-Premise Poller to run custom pings and keep an eye on synthetic testing between branch offices. By enabling you to spot changes and irregularities in your network, this will also aid in security analysis.
Check the network’s bandwidth quality and make sure it is allocated properly.
Network traffic monitoring tool for all your needs:
Optimize data use across your network: In most networks, bandwidth hogs are an unpleasant but prevalent presence. Determine the application, the port, and the interface that are using up the most bandwidth. Optimize network data usage by blocking or restricting that specific IP address or port.
Secure your network by tracking anomalies:Using real-time charts and dashboards, you may spot abnormalities such atypical surges in traffic, data use, volume, or packets from your apps. In a chat, dig into the IP address that triggered the increase at both the source and destination levels.
Leverage dashboards to identify top users: Obtain premium dashboards for the top N protocols, applications, and chats. Find the main consumers of your network’s bandwidth at a glance. View a special health dashboard that displays the most popular devices based on traffic and volume, as well as the most popular interfaces based on bandwidth usage.
Simplify classification using templates:The incoming traffic sources are categorised using application templates and Differentiated Services Code Point (DSCP) templates. The preconfigured application templates’ predefined port and protocol values are compared to the list of apps. On the other hand, DSCP is used to categorise and control network traffic in order to gather statistics on the quality of service.
Receive alerts about busy interfaces :Set threshold limits for all important indicators and sign up to get alerts when they’re crossed so you can act quickly to fix the problem. You can also implement this at the interface level to receive an alert when your traffic or bandwidth usage exceeds predetermined thresholds.
Support for devices from multiple vendors:Gather and examine data on flows from a variety of manufacturers, including Cisco, HP, Juniper, Fortinet, SonicWall, Dell, Palo Alto, 3Com, Foundry Networks, and others. Simply set up your devices to export flows to Site24x7 to get going. Additionally, LoginVeic supports all crucial protocols and data formats.
Know the top N traffic generators: View the top N chats, protocols, and applications by traffic generation or receipt. These statistics for source IP address, destination IP address, port, protocol, DSCP, and traffic for each conversation in your network can also be used to get this information interface-wise.
Organize your traffic analysis using reports : The LogicVein network traffic analysis tool gathers and presents traffic information as tabular data and simple graphics. Then, you may compile this data into reports that you can create on a regular basis, export in multiple forms, and present to management.
One solution for all your network management needs: From a single, SaaS-based monitoring panel, LogicVein delivers network monitoring for device and interface monitoring, network traffic monitoring to analyse flows based on various technologies including NetFlow, J-Flow, and sFlow, and NCM to manage network configuration backups. Without switching between software programmes, you may easily control your network from a single console.
Overview of network traffic monitoring:
What is network traffic?
Network traffic is the volume of data travelling from a source to a destination over a network at any given moment. The essential building blocks of network data transfers are packets, which make up the conveyed data. Traffic data is broken into distinct packets during data transfer from the source and afterwards reassembled at the destination.
various traffic types
Real-time traffic calls for the transmission of high-quality data and is time-sensitive.
Non-instantaneous traffic Traffic used by a programme to conduct routine business
Network traffic monitoring involves tracking the sources, destinations, applications, ports, and protocols used in communication in order to analyse the traffic that moves over a network. Understanding the behaviour of your network is greatly aided by the enhanced visibility and priceless insights that come from monitoring network traffic. By examining network device traffic, also assists you in identifying performance and security issues within the network (i.e., traffic through routers, switches, firewalls, and servers).
The advantages of network traffic monitoring include:
helps to identify bandwidth problems
lists the most active talkers
enhances user experience
What is NetFlow?
The most widely used flow technology was developed by Cisco and is called NetFlow. All traffic that enters and leaves an interface is tracked and recorded. For flow data analytics, NetFlow is frequently utilised. The source address, a destination address, source port, destination port, and protocol values are among the details carried by NetFlow datagrams in the flow record. The most utilised versions of NetFlow are 5 and 9.
Using NetFlow traffic analysis, you can:
Spot network bottlenecks.
Analyze situations where the network performance was bad.
How do you monitor network traffic?Losses in terms of money or resources may be the outcome of poor network performance. You must keep an eye on network traffic if you want to avoid such situations. You can quickly monitor any suspicious behaviour and improve your network traffic with network traffic monitoring.
Here are the procedures you must follow to start monitoring network traffic:
Choose the locations where you want to keep an eye on the traffic. For instance, you can choose routers, switches, and firewalls to monitor their interface data rather than picking individual devices. This enables you to keep an eye on the traffic moving via the related hardware.
Use the LogicVein network traffic monitoring tool to keep an eye on the traffic passing through your source and destination devices’ interfaces. You can examine your monitoring data through dashboards and consolidated reports, which include interface-level information as well as insights based on the IP address, application, and protocol.
Can I see what others are doing on my network?
Yes. You may check your network’s IP and application traffic statistics using NetFlow monitoring, which enables you to determine which specific IP and application have created or consumed the most traffic.
How do I control network traffic?
By setting threshold limits for all of the crucial metrics, including bandwidth usage and inbound and outbound traffic, you may regulate network traffic. You will get warnings if the traffic or bandwidth exceeds your configured settings once these thresholds are in place. You can identify and stop the specific programmes or ports that are at fault using these notifications.
