efluentc

efluentc is the Client OTP application for Fluentd.

efluentc design is to make it more faster to send some messages which are buffered at a time, and reduce count of transmission.

If you can see performance degration that is casued by burst traffic, I'd recommend increasing concurrency of fluent clients.

efluentc has interval to flush messages and buffer size, and you can adjust theses. It is recommeneded that theses parameters are set appropriate value according to your application flow rate.

Available parameters below:

name default description
worker_size 2 send of concurrency
flush_timeout 50 interval of flushing buffered data (msec)
buffer_size 10KB if over buffer size, flush all buffered data
host localhost fluentd host name
port 24224 fluentd port number

sample(app.config):

[
  {efluentc, [{worker_size, 10},      % 10 workers
              {fluesh_timeout, 500},  % 500msec
              {buffer_size, 1048576}, % 1MiB
              {host, localhost},
              {port, 24224}]}
]

Usage

add rebar.config:

{efluentc, "0.1.0"}

efluentc api:

> efluentc:post(<<"test.tag">>, <<"message">>).
ok

> efluentc:post('test.tag', <<"message">>).
ok

> efluentc:post('test.tag', "message").
ok

> efluentc:post('test.tag', #{<<"key">> => <<"value">>}).
ok
