Hi, This patch was supposed to be v2, but I forgot to mention that in the subject. Previous version: https://patchwork.ozlabs.org/patch/792730/ Let me know if you want me to re-sent it with a proper version. Regards, Przemek > -----Original Message----- > From: Szczerbik, PrzemyslawX > Sent: Wednesday, July 26, 2017 10:44 AM > To: dev@openvswitch.org > Cc: Szczerbik, PrzemyslawX <przemyslawx.szczerbik@intel.com> > Subject: [PATCH 2/2] ofproto-dpif-ipfix: add interface Information Elements to > flow key > > Extend flow key part of data record to include following Information Elements: > - ingressInterface > - ingressInterfaceType > - egressInterface > - egressInterfaceType > - interfaceName > - interfaceDescription > > In case of input sampling we don't have information about egress port. > Define templates depending not only on protocol types, but also on flow > direction. Only egress flow will include egress information elements. > > With this change, dpif_ipfix_exporter stores every port in hmap rather > than only tunnel ports.

Hello Greg, Unfortunately Przemek is not available, but I'm more or less familiar with this patch. Did you manage to fix this issue? I think that your problems lies on connection level, which wasn't modified by this patch. Patch added additional counters on reporting level, and based on your description, ovs just can't connect to collector.

I think that your problems lies on connection level, which wasn't modified by this patch.

However, I need to test the patch and ran into problems while trying to do so. Since then I've been pulled into some other work and will get back to this afterwards. I'll just need to debug the connection issue to the collector.

Michal, The good news is that I have my ntopng/nprobe ipfix collector properly configured now and can see flows, hosts, etc. when I enable IPFIX. So I'm ready to test these two patches from Przemyslaw: https://patchwork.ozlabs.org/patch/793773/ https://patchwork.ozlabs.org/patch/793772/ Unfortunately the patches no longer apply to master.

Michal, I'm not sure what has happened but I can't find your V3 patches in my mail but they are in patchwork. I tested the patches and they seem to work fine, or at least the code executes and I didn't see any serious regression. My ntopng/nprobe setup accepted the new template. However, I am seeing this now: 5/Sep/2017 15:11:16 [Lua.cpp:74] ERROR: ntop_get_interface_host_info : expected string, got nil 15/Sep/2017 15:11:16 [Lua.cpp:6658] WARNING: Script failure [/usr/share/ntopng/scripts/lua/iface_ndpi_stats.lua][/usr/share/ntopng/scripts/lua/iface_ndpi_stats.lua:31: attempt to index global 'stats' (a nil value)] 15/Sep/2017 15:11:16 [Lua.cpp:74] ERROR: ntop_get_interface_host_info : expected string, got nil 15/Sep/2017 15:11:15 [Lua.cpp:6658] WARNING: Script failure [/usr/share/ntopng/scripts/lua/iface_ndpi_stats.lua][/usr/share/ntopng/scripts/lua/iface_ndpi_stats.lua:31: attempt to index global 'stats' (a nil value)] 15/Sep/2017 15:11:15 [Lua.cpp:74] ERROR: ntop_get_interface_host_info : expected string, got nil 15/Sep/2017 15:11:12 [Lua.cpp:6658] WARNING: Script failure [/usr/share/ntopng/scripts/lua/iface_ndpi_stats.lua][/usr/share/ntopng/scripts/lua/iface_ndpi_stats.lua:31: attempt to index global 'stats' (a nil value)] 15/Sep/2017 15:11:12 [Lua.cpp:74] ERROR: ntop_get_interface_host_info : expected string, got nil 15/Sep/2017 15:11:09 [Lua.cpp:6658] WARNING: Script failure [/usr/share/ntopng/scripts/lua/iface_ndpi_stats.lua][/usr/share/ntopng/scripts/lua/iface_ndpi_stats.lua:31: attempt to index global 'stats' (a nil value)] 15/Sep/2017 15:11:09 [Lua.cpp:74] ERROR: ntop_get_interface_host_info : expected string, got nil 15/Sep/2017 15:11:09 [Lua.cpp:6658] WARNING: Script failure [/usr/share/ntopng/scripts/lua/iface_ndpi_stats.lua][/usr/share/ntopng/scripts/lua/iface_ndpi_stats.lua:31: attempt to index global 'stats' (a nil value)] 15/Sep/2017 15:11:09 [Lua.cpp:74] ERROR: ntop_get_interface_host_info : expected string, got nil Also, in patch 1/2 though the interface is hard coded to Ethernet in this bit of the patch: + /* Once DPDK library supports retrieving ifType we should get this value + * directly from DPDK rather than hardcoding it. */ + smap_add_format(args, "if_type", "%"PRIu32, IF_TYPE_ETHERNETCSMACD); + smap_add_format(args, "if_descr", "%s %s", rte_version(), + dev_info.driver_name); I'd like to get Darrel Ball's take on this so I've CC'd him.

It took a while but I was able to reproduce without your patches applied.

OK, that sounds fine to me. As I had stated, I'm new to this code base so I just wanted to make sure that due diligence with the change had been done.

Extend flow key part of data record to include following Information Elements: - ingressInterface - ingressInterfaceType - egressInterface - egressInterfaceType - interfaceName - interfaceDescription In case of input sampling we don't have information about egress port. Define templates depending not only on protocol types, but also on flow direction. Only egress flow will include egress information elements. With this change, dpif_ipfix_exporter stores every port in hmap rather than only tunnel ports. It allows to easily retrieve required information about interfaces during sampling upcalls.
