Download and install

sFlow-RT requires Java 1.8+. The following commands download, install and run the software:

wget https://inmon.com/products/sFlow-RT/sflow-rt.tar.gz
tar -xvzf sflow-rt.tar.gz
cd sflow-rt
./start.sh

Alternatively, the following command runs sFlow-RT in a Docker container (see sflow/sflow-rt for more options):

docker run -p 8008:8008 -p 6343:6343/udp sflow/sflow-rt

Use 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:

• sflow-rt-2.3-1332 .noarch.rpm
• sflow-rt_2.3-1332 .deb

Package files are installed under the path /usr/local/sflow-rt/ and log files are directed to /usr/local/sflow-rt/log/sflow-rt-<N>.log

There are no access controls built into sFlow-RT. However, HTTP access can be restricted to the local host by setting the http.hostname property to 127.0.0.1 and a reverse proxy can then be used to secure remote access to the REST API.

The following Apache configuration makes the sFlow-RT REST API accessible 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/
  <IfModule mod_headers.c>
    RequestHeader append X-Forwarded-Prefix "/sflow-rt/"
  </IfModule>
</IfModule>
<Location /sflow-rt/>
  # insert access policy below
</Location>

Alternatively, the following is an equivalent configuration for NGINX:

location /sflow-rt/ {
  proxy_buffering off;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_set_header X-Forwarded-Prefix /sflow-rt/;
  proxy_set_header Host $host;
  proxy_pass http://localhost:8008/;
  proxy_redirect ~^http://[^/]+(/.+)$ /sflow-rt$1;
  # insert access policy below
}
