Our verdict on sFlowTrend
sFlowTrend is a free graphical network and server monitoring tool for small deployments using sFlow-enabled switches or hosts. It shows real-time bandwidth usage by users and applications, monitors physical and virtual server performance, and provides browser-based access through a continuously running server. Windows and Linux distributions are available, along with a Docker image, making it suitable for teams that want a self-hosted monitoring setup without a subscription cost.
Its core strength is focused visibility into current network activity. The product can identify top bandwidth users and applications, monitor up to five sFlow-enabled switches or hosts, analyze traffic trends, and produce historical reports. Thresholds and alerts help identify abnormal traffic conditions, while SNMP v2c and SNMP v3 communication adds switch monitoring alongside sFlow data. This combination fits administrators who need practical bandwidth and server signals rather than a broad network management suite.
The main trade-off is scale and retention. The free edition supports only five monitored switches or hosts and keeps one hour of data in memory, which limits longer-term analysis and larger environments. Its reliance on sFlow also makes it a narrower choice than tools designed around wider protocol coverage or bigger infrastructures. Choose sFlowTrend for a small, self-hosted deployment that needs real-time top-user, application, server, and alerting views at no cost. Larger networks or teams requiring extended history should consider a more scalable alternative.
