fluentd (td-agent) note

fluentd ver 1.x

multiprocess

<system>
workers 2
</system>

But any plugins do not supprt multiprocess e.g. debug_agent.

sender sample

<source>
  @type tail
  path /tmp/test.log
  pos_file /tmp/td-pos/test.log
  tag hoge.test
  format none
  read_from_head true
</source>

<match hoge.**>
  @type forward
  <server>
    host <your fluend-server>
    port 24224
  </server>
  buffer_type file
  buffer_path /tmp/buff/test.*.buff
  flush_at_shutdown true
</match>

out_file

path = buffer_path

The path parameter is used as buffer_path in this plugin.
So..
- No need to set buffer_path.
- If you dislike bufferd path like "/path/to/file.20140101.log.b4eea2c8166b147a0", set flush_interval 0s

Of course , even if you set flush_interval 0s, buffers path created at the moment.

output RAW format

format single_value retruns parts of JSON message: key. If you return other key, set message_key <YOUR_KEY>. i.e.) default is message_key message

Stop split!

append true

symlink_path

Link to latest buffer file. But when just after logrotate (kill USR1) or no buffer file, this link to be a dead link.

symlink_path can not set * (wild card)

out buffer

default limit

type	buffer_chunk_limit	buffer_queue_limit	total
