For sophisticated deployments we offer option to export metrics to InfluxDB using Kafka queue engine.
It may be useful in case when you need redundancy and cannot lost even single metric.
FastNetMon does not support authorization or encryption, it supports only plain Kafka connection. FastNetMon does not implement batching and exports traffic for each network or host as separate message. Your consumer (we can suggest using Telegraf) should implement batching. FastNetMon does not acknowledge every sent message.
This guide requires that you already enabled InfluxDB support.
You can enable Kafka export this way:
sudo fcli set main influxdb_kafka enable
sudo fcli set main influxdb_kafka_topic fastnetmon
You can add multiple brokers using IP addresses or host names. Each host name can be resolved to multiple IP addresses too:
sudo fcli set main influxdb_kafka_brokers 10.154.0.1:9092
sudo fcli set main influxdb_kafka_brokers 10.154.0.2:9092
sudo fcli set main influxdb_kafka_brokers 10.154.0.3:9092
To spread load over available partitions, we offer multiple options:
sudo fcli set main influxdb_kafka_partitioner random
FastNetMon has support for following partitioners:
