Henrik, here you go: Two more netstat data chunks that cause the Duplication error (parsing issue?) in rrd/hobbit. My simple observation is the one thing these two hosts have in common is virtual network interfaces, so instead of simpler items like eth0, eth1 and so on, you have eth0, eth0:0, and so forth. Linux in this case, but that would apply to solaris and so on as well. Just a hunch................. @@data#98185|1154614736.024527|192.168.224.202||dunn.hmgc.mcw.edu|ifstat data dunn,hmgc,mcw,edu.ifstat linux eth0 Link encap:Ethernet HWaddr 00:09:3D:13:DC:AB inet addr:192.168.224.105 Bcast:192.168.224.255 Mask:255.255.255.0 inet6 addr: fe80::209:3dff:fe13:dcab/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:40318794 errors:0 dropped:0 overruns:0 frame:0 TX packets:15352953 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:2942042461 (2.7 GiB) TX bytes:21803054108 (20.3 GiB) Interrupt:185 eth0:0 Link encap:Ethernet HWaddr 00:09:3D:13:DC:AB inet addr:192.168.224.107 Bcast:192.168.224.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:185 eth0:1 Link encap:Ethernet HWaddr 00:09:3D:13:DC:AB inet addr:192.168.224.160 Bcast:192.168.224.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:185 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:37737 errors:0 dropped:0 overruns:0 frame:0 TX packets:37737 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:6042388 (5.7 MiB) TX bytes:6042388 (5.7 MiB) @@ @@data#98366|1154614859.203728|192.168.224.202||clifford.hmgc.mcw.edu|if stat data clifford,hmgc,mcw,edu.ifstat linux eth0 Link encap:Ethernet HWaddr 00:09:3D:13:C8:78 inet addr:192.168.224.104 Bcast:192.168.224.255 Mask:255.255.255.0 inet6 addr: fe80::209:3dff:fe13:c878/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:146220628 errors:0 dropped:0 overruns:0 frame:0 TX packets:42544430 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:14048692258 (13.0 GiB) TX bytes:57506442876 (53.5 GiB) Interrupt:185 eth0:0 Link encap:Ethernet HWaddr 00:09:3D:13:C8:78 inet addr:192.168.224.106 Bcast:192.168.224.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:185 eth0:1 Link encap:Ethernet HWaddr 00:09:3D:13:C8:78 inet addr:192.168.224.159 Bcast:192.168.224.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:185 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:1189289 errors:0 dropped:0 overruns:0 frame:0 TX packets:1189289 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:347179798 (331.0 MiB) TX bytes:347179798 (331.0 MiB) @@ --------------------------------------------------------- Kent C.
