Vladimir's blog has a solution that involves tailing the Apache log files: http://vuksan.com/linux/ganglia/#Apache_Traffic_Stats
The sFlow protocol packs a large number of metrics in each UDP datagram, so you should see a reduction in UDP datagrams per second associated with monitoring. The C based mod-sflow / host-sflow agents have a small memory and CPU footprint. On Thu, Dec 31, 2015 at 3:14 PM, Aaron <hawaiiaa...@gmail.com> wrote: > Thanks Peter.
