What is a Network Sniffer (or) Network Packet Sniffer? 

The recent growth of the Internet and the World Wide Web has given life to so many industries over the journey of its evolution which appears to be continuing. However, the troubles that come with using a large scale networks are also numerous. With the right network sniffing tool, be prepared to capture and analyze network traffic, to identify the cause of any network performance drops and prevent them from happening again.

Network traffic sniffers are applications which are either a software or hardware tool to  intercept, log, and analyze network traffic and data. A network packet sniffing tool can help you target weak points when expanding your network capacity, managing your bandwidth, enhancing network security, etc and hence improve end-user experience. Some of the Benefits of using a network sniffer include the following

  • Identify the Root Cause
  • Analyze Traffic by Type
  • Improve Bandwidth
  • Improve Security

NetFlow Analyzer: Deep Packet Inspection

ManageEngine Netflow Analyzer is a network packet analysis tool that can be leveraged as a network packet sniffer by passively monitoring the session to provide details like host names, open ports, and so on, without causing any hindrance to the traffic.

NetFlow Analyzer's Deep Packet Inspection solution allows you to capture packets from the network flows and analyzes the packet capture (PCAP) files. The DPI monitoring mechanism relies on packet-level analysis to determine whether the network or the application is at fault. It gives network admins clear visibility into the volumes of bandwidth consumed by each application from the enterprise network and helps them diagnose the problems in application performance with response time details and further to the root cause of any performance degradation.

Pinpoint the Root Cause

With real-time insights and detailed analytics, the network administrators can discover traffic patterns and device performance, and easily pinpoint whether the delay is on the network side or application side. Drill-down to a particular application or URL and view real-time traffic and response time graphs to pinpoint the fault and improve the network or application availability.

The conversation report identifies the top source and destination IP's that are experiencing high ART (Application Response Time) and NRT (Network Response Time). Know when it is time to expand your bandwidth, and when it is better to implement a new policy.

Analyze Traffic by Type

Higher Bandwidth doesn't always mean better network performance, get accurate reports for application traffic and troubleshoot bandwidth issues to determine which customer or application should receive bandwidth priority. Pull the list of affected users for slow apps and communicate with them in advance to Increase application availability and meet the SLAs (Service Level Agreements).

Know who is using your bandwidth and regulate them using traffic shaping techniques like ACL or editing class-based Service policy (CBQoS).

Improve Bandwidth

Measure network bandwidth usage at any particular time and resolve the issues on time before end-users are affected. The various reports in Netflow Anazlyzer, helps the network admins to drill-down further into the network to understand which applications consume more bandwidth in the network.
