AS-Stats not working with sFlow data from Brocade/Extreme NetIron routers #103
Description
Hello,
it seems as-stats is not working with sFlow data from Brocade/Extreme NetIron devices. No RRD-files are being created within the data-directory. Running asstatd.pl in debug mode produces the following output:
# /opt/as-stats/bin/asstatd.pl -P 2080 -p 0 -r /opt/as-stats/data/rrd -k /opt/as-stats/conf/knownlinks -a 47251

Our sFlow-config on both routers:
sflow enable
sflow source ve 4000 8888
sflow destination 192.168.236.100 2080
sflow polling-interval 30
sflow sample 1024
and on all interfaces we have set:
sflow forwarding
And the knownlinks-file (separated with tabs):
# Router IP ifindex tag description color samplingrate
192.168.236.1 1 uplink1 Transit1 239614 1024
192.168.236.1 2 uplink2 Peering1 4167B5 1024
192.168.236.2 1 uplink3 Transit2 721358 1024
192.168.236.2 2 uplink4 Peering2 EA891B 1024
By using tcpdump we can confirm that sFlow-data is being received on the collector host. Other sFlow monitoring tools are also working as expected - only as-stats does not work. Maybe any hints?
Thanks in advance
