Network bandwidth monitoring

Network bandwidth monitoring involves tracking and analyzing the volume of data that flows through a network. It measures the actual bandwidth on a LAN or WAN and helps to identify potential bottlenecks and outages. It is important to analyze the bandwidth metrics on a network at the device and interface level. Site24x7 analyzes flow based on different technologies like NetFlow, sFlow, and J-Flow. With stats on peak traffic, top applications, and top conversations, you can obtain complete visibility into the network bandwidth. Identify bandwidth hogs, fix them, and boost your network performance using Site24x7's network bandwidth monitoring software.

Benefits of network traffic monitoring

Machine-to-machine traffic has been the biggest traffic generator of the decade. As a network administrator, you need a network monitoring tool to keep an eye on your network. Additionally, you need to track how much traffic is passing through your network. Also, management may want to know about any bandwidth hog, intrusion, slowness, or unauthorized access.

By using a network traffic monitoring tool, you can:

  • Spot peaks, heavy incoming traffic from a particular application, or a port that is clogged with incomplete processes.
  • Obtain detailed stats and reports which you can use to quickly fix these issues.
  • Identify where the traffic is generated in a data center scenario.
  • Track traffic moving between the main office and branch offices.
  • Perform custom pings and monitor synthetic tests between branch offices using Site24x7 On-Premise Poller. This will also help you with security analysis, allowing you to detect changes and anomalies in your network.
  • Test the quality of network bandwidth and ensure appropriate allocation.

Network traffic monitoring tool for all your needs

Optimize data use across your network

Bandwidth hogs are an unwanted but common presence in most network. Identify the application and port hogging bandwidth, and the interface through which that heavy traffic has flown. Block or restrict that particular IP or port in your environment, and optimize data use across the network.

Secure your network by tracking anomalies

Identify anomalies like unusual spikes in traffic, data utilization, volume, or packets from your applications using real-time charts and dashboards. Drill down to the IP address that caused the spike both at the source and the destination level in a conversation.

Leverage dashboards to identify top users

Obtain exclusive dashboards for top N applications, protocols, and conversations. In a single glimpse, identify major users of your network bandwidth. View an exclusive health dashboard showing top devices by traffic and volume, and top interfaces by traffic, volume, and bandwidth utilization.

Simplify classification using templates

Application templates and Differentiated Services Code Point (DSCP) templates are used to classify the incoming traffic sources. The port and protocol values are defined in preconfigured application templates and are matched with the list of applications. DSCP, on the other hand, is used to classify and manage network traffic to obtain the quality of service stats.

Receive alerts about busy interfaces

Configure threshold limits for all key metrics and receive alerts when they're breached so that you can execute corrective measures on time. You can also do this at the interface level so that you'll get a notification when your traffic or bandwidth utilization exceeds certain limits.

Support for devices from multiple vendors

Collect and analyze flows from multiple vendors like Cisco, HP, Juniper, Fortinet, SonicWall, Dell, Palo Alto, 3Com, Foundry Networks, and more. To get started, simply configure your devices to export flows to Site24x7. Site24x7 also supports all important protocols and data types.

Know the top N traffic generators

View the top N applications, protocols, and conversations that have generated or received the most traffic. You can also obtain these details interface-wise with stats like source IP address, destination IP address, port, protocol, DSCP, and traffic for every conversation in your network.

Organize your traffic analysis using reports

Site24x7's network traffic analysis tool collects and displays traffic data as tabular data as well as easy-to-interpret graphs. This data can then be consolidated into reports, which you can generate periodically, export in different formats, and submit to management.

Overview of network traffic monitoring

What is network traffic?

Network traffic is the amount of data moving across a network from a source to a destination at a given point in time. The data transferred is comprised of packets, which are the fundamental units of network data transfers. During data transmission, traffic data from the source gets divided into individual packets and is reassembled at the destination later.

Types of traffic:

What is network traffic monitoring?

Network traffic monitoring is the process of analyzing the traffic that flows across a network by keeping track of its source; its destination; and the applications, ports, and protocols involved in the conversation. Monitoring network traffic provides improved visibility and invaluable insights that are highly beneficial to understanding your network's behavior. It also helps you weed out performance and security issues within the network by analyzing network device traffic (i.e., traffic through routers, switches, firewalls, and servers).

Benefits of using network traffic monitoring:

What is NetFlow?

NetFlow was created by Cisco and is the most commonly used flow technology. It tracks and records all traffic as it enters and exits an interface. NetFlow is often used for flow data analytics. NetFlow datagrams carry information like the source address, destination address, source port, destination port, and protocol values in the flow record. NetFlow versions 5 and 9 are most commonly used.

With NetFlow traffic analysis, you can:

What is J-Flow?

Juniper Networks developed the data flow sampling technique known as J-Flow, which the SRX Series devices support. The data includes all network activities, such as conversations inside enabled ports, and also identifies top talkers. J-Flow works by monitoring each packet that flows inside a network. It allows packets in the input stream to be sampled when enabled on an interface.

With J-Flow traffic analysis, you can:

What is sFlow?

Sampled flow, commonly known as sFlow, is the standard technology for packet export at Layer 2 of the Open Systems Interconnection (OSI) model. As a packet sampling technology, sFlow samples IP packets moving from a source to a destination through a particular port. It provides the means of exporting truncated packets together with the interface counters. sFlow uses sampling to achieve scalability and is used for high-speed networks.

sFlow has two types of sampling:

How do you monitor network traffic

Adverse network performance can result in losses in terms of costs or resources. To prevent such instances, you need to monitor network traffic. With network traffic monitoring, you can easily track any suspicious activity and optimize your network traffic.

To begin, here are the steps you need to follow while monitoring network traffic:

Can I see what others are doing on my network?

Yes. Using NetFlow monitoring, you can view your network's IP and application traffic stats, which help you know which particular IP and application have generated or consumed the most traffic.

How do I control network traffic?

You can control network traffic by configuring threshold limits for all the critical metrics, like in and out traffic and bandwidth utilization. With these thresholds in place, you will receive alerts whenever the traffic or bandwidth breaches your configured values. Based on these alerts, you can identify the particular applications or ports that are responsible and block them.
