sFlowTrend

sFlowTrend is a graphical monitor for network traffic, servers, and applications, best suited to people managing sFlow-enabled switches or hosts. Its combined traffic and host view is useful for diagnosing bandwidth use, but the free plan’s five-device and one-hour limits—and its restriction on commercial use—narrow its role.

Overview

sFlowTrend uses sFlow data and extensions to connect network, server, and application performance in one view. It can help identify bandwidth consumption, abnormal traffic, host CPU and memory use, and usage trends for upgrade planning. That makes it a focused option for environments whose switches or hosts send sFlow; it will not monitor devices that lack that protocol.

Key features

• Traffic and application visibility: Real-time views of top network users and applications help locate bandwidth demand and investigate unusual traffic.
• Host and user monitoring: CPU and memory utilization, application monitoring, and user monitoring give administrators context beyond flow traffic.
• SNMP and bandwidth alerts: SNMP monitoring and alerts add device monitoring and a way to flag bandwidth concerns.
• Short-term history: Usage trends can inform upgrade planning, but the free plan keeps only one hour of data in memory. It is therefore more suited to current investigations than to long-range trend analysis.

Pricing

The sFlowTrend plan costs nothing and supports at most five switches or hosts, with one hour of data stored in memory. That cap makes it a practical starting point for a small sFlow environment, but not a fit for larger deployments or teams that need longer history.

The license grants a non-exclusive, non-transferable right to use one copy. Commercial use requires separate written authorization and applicable fees, so organizations should not treat the free price as permission to deploy it commercially. The software is provided as-is without warranty. Pricing for paid use is on request.

Platforms

sFlowTrend is written in Java, runs on most platforms, and requires Java 11 or later. Downloads include Windows, Windows 64-bit with a 64-bit JRE, a Linux installer, Linux RPM, Debian .deb, and a Docker image. From version 7.0, users access the installed server through a web client at localhost port 8087 over HTTP or port 8443 over HTTPS. The combination of deployment choices suits varied server setups, while the Java requirement and local-server arrangement are operational considerations.

Who it's for

sFlowTrend fits administrators who have sFlow-enabled network or host devices and want a compact view of traffic, applications, and host utilization. It is less suitable when devices do not export sFlow, when monitoring must cover more than five devices on the free plan, or when commercial use is needed without a separate authorization.

Pros and cons

• Pros: Combines sFlow-based traffic, application, and host performance views; adds SNMP monitoring and bandwidth alerts; offers Windows, Linux, Docker, and web-client access.
• Cons: Requires sFlow data from monitored switches or hosts; the free plan is limited to five devices and one hour of in-memory data; commercial use needs separate written authorization and fees.

Alternatives

For a broader set of bandwidth-monitoring options, browse Bandwidth Monitoring Software.

• ntopng is worth considering for a free community option designed for home and network practitioners, with a suggested maximum of 256 live local hosts.
• SoftPerfect Bandwidth Manager may suit readers who want rules, usage reports, and a live usage monitor; its free Lite plan is limited to five rules or streams.
• GlassWire is an alternative for Windows, Android, or web users who want a free plan with one day of bandwidth usage and 24 hours of network history.
• ManageEngine NetFlow Analyzer may be preferable when a free edition limited to two interfaces or paid editions priced per month better match the deployment.
• Sniffnet is a free, open-source option for Linux, macOS, or Windows.
• bwmon is a free, self-hosted choice for monitoring a single Linux host.
• MRTG is a free option for monitoring SNMP devices and other data sources.
• Nagios XI is another option, with a free tier capped at seven nodes or 100 services, whichever comes first.

Verdict

Choose sFlowTrend if you manage a small, sFlow-enabled environment and need a combined view of network traffic, applications, and host utilization. Its protocol-specific focus is its main strength; the one-hour history, five-device cap, and commercial-use restriction are reasons to look elsewhere for ongoing business monitoring or broader coverage.
