sFlowTrend
sFlowTrend is a graphical tool for monitoring network and server activity, including leading network users and applications in real time. It uses sFlow and extensions to connect network, server, and application performance information. It can help identify bandwidth use, unusual traffic, host CPU and memory utilization, and usage trends for upgrade planning. Monitoring requires switches or hosts that send data using the sFlow standard. The software is written in Java and requires Java 11 or later; available downloads include Windows, Linux installers and packages, and a Docker image. From version 7.0, users connect to an installed server through a web client over HTTP or HTTPS. The free plan supports at most five switches or hosts and stores one hour of data in memory. The license permits one copy and bars commercial use without separate written authorization and applicable fees. It provides the software as-is without warranty. Pricing is available on request for other use.
