Subject: Re: [Ganglia-general] Ganglia and sFlow
The following article provides additional information on configuring the
Ganglia development branch (trunk) to collect sFlow:
http://blog.sflow.com/2010/10/ganglia.html
Installing and configuring Host sFlow agents to send sFlow from Linux and
Windows platforms is described in the articles:
http://blog.sflow.com/2010/10/installing-host-sflow-on-linux-server.html
http://blog.sflow.com/2010/10/installing-host-sflow-on-windows-server.html
sFlow is sent from the Host sFlow agents to the Ganglia gmond collector as
unicast UDP messages to port 6343. You need to make sure that each Host sFlow
agent is configured to send to the IP address of the server that gmond is
installed on (the configuration details are in the articles above). If you are
still having problems then check that there are no firewalls blocking the
traffic. The IP tables filters on the the collector and agents and well as any
intermediate firewalls must be configured allow UDP port 6343 traffic to pass.
You can confirm that sFlow is being received at the gmond server by running the
following tcpdump command:
tcpdump udp port 6343
Please let me know if you have any difficulties.

i'm trying to use ganglia with sFlow. I have installed gmond patched for
using sFlow on a host and installed the sFlow agent onto a different host. The
problem is that it seems to me that never is changed (the xml of gmond seems
the same). How can i anderstand that all is working right??? the sFlow angent
run well and send to the host on with is installed gmond the packets.....
thanks a lot
