filebeat-kafka:WARN producer/broker/0 maximum request accumulated, waiting for space

You need to configure 3 things:

• Brokers

• Filebeat kafka output

• Consumer

Here a example (change paths according your environment).

Broker configuration:

# open kafka server configuration file
vim /opt/kafka/config/server.properties

# add this line
# The largest record batch size allowed by Kafka.
message.max.bytes=100000000

# restart kafka service
systemctl restart kafka.service
Filebeat kafka output:

# Consumer configuration:

# larger than the max.message.size
max.partition.fetch.bytes=200000000

# 以下内容可以不添加
output.kafka:
  ...
  max_message_bytes: 100000000
