sFlow-RT™ incorporates InMon's asynchronous analytics technology (patent pending), delivering real-time visibility to Software Defined Networking (SDN), DevOps and Orchestration stacks and enabling new classes of performance aware application such as load balancing, DDoS protection, and workload placement.
The sFlow-RT analytics engine receives a continuous telemetry stream from sFlow Agents embedded in network devices, hosts and applications and converts them into actionable metrics, accessible through the RESTflow™ API. The RESTflow API makes it easy for to configure customized measurements, retrieve metrics, set thresholds, and receive notifications. Applications can be external, written in any language that supports HTTP/REST calls, or internal, using sFlow-RT's embedded JavaScript/ECMAScript.
Network visibility is essential to understanding the interaction between scale-out services running on cloud infrastructure. By combining network, host and application monitoring within an integrated analytics pipeline, sFlow-RT provides visibility into applications and the server and network resources needed to sustain performance.

===================================================
http://sflow-rt.com/download.php
Download and install
sFlow-RT requires Java 1.7+. The following commands download, install and run the software:
wget http://www.inmon.com/products/sFlow-RT/sflow-rt.tar.gz
tar -xvzf sflow-rt.tar.gz
cd sflow-rt
./start.shAlternatively, the following command runs sFlow-RT in a Docker container (see sflow/sflow-rt):
docker run -p 8008:8008 -p 6343:6343/udp -d sflow/sflow-rtUse a web browser to connect to http://localhost:8008 to interact with the REST API.
The software is also available as RPM and DEB packages:
Software is installed under the path /usr/local/sflow-rt/ and log files are directed to /usr/local/sflow-rt/log/sflow-rt-<N>.log
Note There are no access controls built into sFlow-RT. However, HTTP access can be restricted to the local host by settings the http.hostname property to 127.0.0.1 and a reverse proxy can then be used to secure remote access to the API. For example, the following Apache configuration settings make the interface accessible on port 80 under the path /sflow-rt/
<IfModule mod_proxy.c>
ProxyRequests off
ProxyVia off
ProxyPass /sflow-rt/ http://127.0.0.1:8008/ retry=0 timeout=5
ProxyPassReverse /sflow-rt/ http://127.0.0.1:8008/
