Hi, We had a working installation which, after an apt upgrade (to latest stable) is now somewhat broken and I’m unable to find why.
Topology is simple: Multiple Cisco devices emitting Netflow -> nprobe instances -> ntopng (The probes and ntopng are on the same machine) All the errors relate to the lack of an interface name, for example: Apr 11 12:46:45 ntopng ntopng: [Lua.cpp:76] ERROR: ntop_select_interface : expected string, got nil Apr 11 12:46:45 ntopng ntopng: [Lua.cpp:76] ERROR: ntop_interface_name2id : expected string, got nil Apr 11 12:46:45 ntopng ntopng: [Lua.cpp:5134] WARNING: Script failure [/usr/share/ntopng/scripts/lua/as_stats.lua][/usr/share/ntopng/scripts/lua/modules/lua_utils.lua:1686: attempt to concatenate local 'interface_name' (a nil value)] The web interface reports this at the bottom of every page and most of the pages are unable to display data because of it: /usr/share/ntopng/scripts/lua/if_stats.lua:72: attempt to concatenate global 'ifid' (a nil value) [NTOPNG.CONF] -i="tcp://127.0.0.1:95101" -i="tcp://127.0.0.1:95201" -i="tcp://127.0.0.1:95301" -i="tcp://127.0.0.1:95302" -i="tcp://127.0.0.1:95401" -i="tcp://127.0.0.1:92101" -i="tcp://127.0.0.1:92102" -i="tcp://127.0.0.1:92103" -i="tcp://127.0.0.1:92104" -i="tcp://127.0.0.1:90001" -i="tcp://127.0.0.1:90002" -i="tcp://127.0.0.1:90003" -i="tcp://127.0.0.1:90004" -i="tcp://127.0.0.1:90005" -i="tcp://127.0.0.1:90006" -i="tcp://127.0.0.1:90007" --pid=/var/run/ntopng.pid --community= --max-num-flows=512000 --max-num-hosts=256000 --dns-mode=3 --data-dir=/ntopng --sticky-hosts=none --local-networks="xxx" --collector-sample-rate=20 --disable-login=1 --disable-alerts= --http-port=x.x.x.x:80 --scripts-dir=/usr/share/ntopng/scripts --daemon= --dont-change-user= [NPROBE-EXAMPLE] --collector-port=12101 --zmq=tcp://127.0.0.1:92101 -V=9 -u=2101 -Q=2102 --max-num-flows=250000 --dump-stats=/ntopng/nprobe/rtr-121_1_flows_stats.txt --collector-sample-rate=20 --syslog=RTR-121-01 --dont-drop-privileges= -T="%IPV6_SRC_ADDR %IPV6_DST_ADDR %IPV4_SRC_ADDR %IPV4_DST_ADDR %IPV4_NEXT_HOP %INPUT_SNMP %OUTPUT_SNMP %IN_PKTS %IN_BYTES %OUT_PKTS %OUT_BYTES %FIRST_SWITCHED %LAST_SWITCHED %L4_SRC_PORT %L4_DST_PORT %TCP_FLAGS %PROTOCOL %SRC_TOS %SRC_AS %DST_AS" -g=/var/run/nprobe-121-01.pid Any pointers?
