Export Performance
| Template | Ingress Rate (NetFlow) | Export Rate (ZMQ) |
|---|---|---|
| Default | 12'000 packets/second (avg 19 records/packet) | 230'000 flows/second |
| @NTOPNG@ | 8'500 packets/second (avg 19 records/packet) | 160'000 flows/second |
System Configuration
With indexing and PCAP compression enabled:
- OS: nProbe™ 8.7 Pro
- OS: CentOS Linux 7.6
- CPU: Intel E3-1230 v5 @ 3.40GHz
- Incoming Flows in NetFlow v9 Format
- ZMQ Export (TLV)
- Internal Cache Disabled (guarantees transparent incoming flow forwarding from nProbe)
- Command used:
nprobe -i none -n none –collector-port 2055 –zmq tcp://192.168.1.1:5556 –disable-cache [-T @NTOPNG@]
- No flow storage on database or disk - only forwarding to ntopng as collector via ZMQ.
- The bandwidth required for exporting flow information over ZMQ is <30 Mbit/sec for 10’000 flows/second, this number can be scaled based on the actual number of flows. For example, when processing 1 Gbit/s average internet traffic, the bandwidth required is <5 Mbit/s as peak (note: this highly depends on traffic type).
