Pinpoint Network Slowdowns Faster With Network Analyzer Software
Pair NetFlow Traffic Analyzer with Network Performance Monitor to see which applications and endpoints are using your bandwidth, and where performance starts to degrade.
See What’s Driving Network Traffic and Bandwidth
When a link slows down, you need to know what's behind it. NetFlow Traffic Analyzer (NTA) breaks traffic down by application, protocol, endpoint, and conversation, while Network Performance Monitor (NPM) shows which interface is under stress. Together, you can go from "the link is busy" to the specific cause, then decide whether to limit that traffic, reroute it, or add capacity.
- Rank the most bandwidth-consuming conversations across the whole monitored network, not just one device
- See which external autonomous systems send the most traffic through a node or interface
- Compare ingress and egress bytes and packets for each application
- Find traffic on unmonitored ports and start tracking it by port with one click
- Report on traffic by IP address group, including groups imported from IP Address Manager (IPAM)
Pair Traffic Analysis With Network Performance Monitoring
NPM tells you where performance is slipping. NTA tells you why. Because flow data is tied to the nodes and interfaces NPM already monitors, the two work as one investigation instead of two separate tools, and your fix is based on what is actually happening on your network.
- Open top applications, conversations, and endpoints directly on NPM node and interface detail pages
- Overlay flow metrics, such as conversation, autonomous system, and country, with device metrics in PerfStack
- Locate the problem hop with NetPath service-path analysis, then check flow data for what is crossing it
- Combine performance and traffic views in drag-and-drop dashboards and scheduled PDF or email reports
Learn How Network Traffic Analyzer Turns Flow Data Into Insight
Routers, switches, and firewalls export flow records that summarize each conversation: who talked to whom, over which ports and protocols, and how much data moved. A network traffic analyzer like NTA collects those records, matches them to the interfaces you monitor, and turns them into charts and reports.
- Use filters, drill-down, and reporting to narrow traffic to the time window and device that matter
- Check which devices are exporting flows and when each one last reported
- Map flow interface IDs to SNMP interface IDs for devices that report them differently
- Get live flow data on day one with the Local NetFlow Source, no device setup required
Spot Bottlenecks and Traffic Spikes Before Users Do
Bottlenecks rarely announce themselves. NTA baselines how your traffic normally behaves and alerts you when it changes, so you can investigate a spike or a silent device before users open tickets. Pair those alerts with NPM's own performance alerts to see the traffic shift and its effect on the device together.
- Start with default top-talker alerts (trigger at 75% utilization, reset at 50%), then tune them
- Quantify bandwidth consumed by each QoS class map, before and after a policy change
- Use port 0 monitoring to flag malicious or malformed traffic
- Isolate unexpected application traffic with traffic forensics views
Analyze Flow Data From Multi-Vendor Network Devices
Most networks are not single-vendor. NTA analyzes flow data from Cisco, Juniper, HP, Palo Alto Networks, Huawei, Extreme Networks, and other vendors, whether it arrives as NetFlow, J-Flow, sFlow, NetStream, or IPFIX, so you get one consistent view of traffic across the whole environment.
- Include Cisco Meraki MX flow data alongside your other flow sources
- Recognize applications with Cisco NBAR2 advanced application recognition
- See what is using wireless bandwidth with wireless LAN controller traffic analysis
- Get prompted to add interfaces that export flow data but are not yet managed in NPM
