Network Sniffer - Network & App Sniffing Tool | SolarWinds (2024)

Tracking packet response times for both networks and applications means you can more easily answer the question, “Is it the network or a specific application that’s causing slowdowns for users?” The sniffer network monitoring tool in SolarWinds® Network Performance Monitor (NPM) helps you narrow down the issue with dashboard displays of top ten Time to First Byte and TCP Handshake metrics. Gain an at-a-glance ability to correlate and identify the source of slowdowns and configure the dashboard to instantly isolate metrics by type, time, or other factors. Drill down into discrete values to understand network traffic in depth.

Network sniffing is an integral part of the network analysis capabilities in NPM. The network sniffing modules are designed to provide insight into top metrics, letting you drill down to troubleshoot and allow admins to set dynamic alerting thresholds. Easily track and analyze the traffic for specific applications with the Quality of Experience (QoE) module. Network sniffing is managed through the NPM dashboard, where admins can see an overview of network response times (TCP Handshake), application response times (Time to First Byte), traffic types, and risk levels. Admins can further create Quality of Experience app management clusters after installing packet analysis sensors. Network Performance Monitor provides a range of features, including customizable alerts, auto-generating intelligent maps, SDN environment monitoring, dynamic baseline calculating, and Network Insight™ visibility across Cisco Nexus, Cisco ASA, and F5 BIG-IP.

With the SolarWinds network sniffing tool, you can automatically classify network traffic according to categories like business vs. social and risk level. Categorize traffic into types based on destination server IP addresses, ports used, and measurement of the total and relative volumes of traffic for each type. Group traffic by categories like file transfer, network monitoring, messaging, remote access, and database use. Using the NPM network sniffer tool, you can also identify excessive levels of non-business traffic—like social media or the use of risky apps—you may need to filter or eliminate.

With NPM, you can identify and monitor over 1,200 applications out of the box, including popular platforms like Skype and Facebook. View specific traffic on your network and automatically calculate application response times. Use the unique QoE dashboard to monitor metrics across specific sets of applications and troubleshoot faster using a realistic view of current user impact. Perform bulk application assignments within the dashboard for quicker management. You can also reconfigure application type or risk designation to fit your business needs.
