Variable in delivery_stream_name #226

rolandjitsu · 2024-02-28T10:55:57Z

It looks like this plugin does not like variable names in the delivery_stream_name:

And the config is:

<match {events,metrics}>
  @type kinesis_firehose
  delivery_stream_name ${tag}-stream
  region ap-southeast-1
  aws_key_id keyid
  aws_sec_key secret

  <buffer>
    flush_interval 5
    chunk_limit_size 1m
    flush_thread_interval 1
    flush_thread_burst_interval 0.01
    flush_thread_count 15
  </buffer>
</match>

Any idea how to get it working?

Hmm, maybe syntax is implemented differently as I can see something about placeholders in https://github.com/awslabs/aws-fluent-plugin-kinesis?tab=readme-ov-file#delivery_stream_name.

So would:

delivery_stream_name "${$.tag}-stream"

work?

simukappu · 2024-02-29T11:47:40Z

The plugin supports this delivery_stream_name ${tag}-stream format since it is tested here:

aws-fluent-plugin-kinesis/test/plugin/test_out_kinesis_firehose.rb

Line 215 in fac107f

"delivery_stream_name" => "stream-placeholder-${tag}",

Can you confirm whether your tag variable violated Kinesis Firehose delivery stream name regulations? regular expression pattern: [a-zA-Z0-9_.-]+

rolandjitsu · 2024-03-01T05:40:30Z

Yes, the stream name is based on:

<match {events,metrics}>
  @type copy
  <store>
    @type kinesis_firehose
    delivery_stream_name ${tag}-stream
    region ap-southeast-1
    aws_key_id keyid
    aws_sec_key secret

    <buffer>
      flush_interval 5
      chunk_limit_size 1m
      flush_thread_interval 1
      flush_thread_burst_interval 0.01
      flush_thread_count 15
    </buffer>
  </store>
</match>

So I'd expect it to be: events-stream and metrics-stream; which is compliant with the regex.

I have something similar setup with https://github.com/uken/fluent-plugin-elasticsearch and that works (impl. is probably different, but the tag matches the ones in the match statement).

I run td-agent, installed on Ubuntu 18.04.6 LTS via apt, with the following version:

td-agent 4.4.1 fluentd 1.15.2 (c32842297ed2c306f1b841a8f6e55bdd0f1cb27f)

When you specify delivery_stream_name configuration with built-in placeholder, you should specify the corresponding attributes in buffer section. Can you try this?
https://docs.fluentd.org/configuration/buffer-section#placeholders

<match {events,metrics}>
  @type copy
  <store>
    @type kinesis_firehose
    delivery_stream_name ${tag}-stream
    region ap-southeast-1
    aws_key_id keyid
    aws_sec_key secret

    <buffer tag>
      flush_interval 5
      chunk_limit_size 1m
      flush_thread_interval 1
      flush_thread_burst_interval 0.01
      flush_thread_count 15
    </buffer>
  </store>
</match>
