Fluentd

local

The local storage plugin stores the key-value pair into a JSON file on local storage.

Parameters

path

Specifies the pathname to save the key-value pair. (default: nil)

mode

Specifies the file access mode. (default: 0644)

dir_mode

Specifies the directory access mode. (default: 0755)

pretty_print

Outputs the human-readable formatted JSON. (default: false)

Attributes

conf.arg

Note that conf.arg provides an alternative path parameter.

<storage awesome_path>
  @type local
</storage>

<system>
  root_dir tmp
</system>

The above configuration will save the internal states, which are handled by storage_local under tmp directory.

NOTE: Specifying the file path in the path parameter does not support the multi-workers feature. Instead, you should specify a directory there.

Example

With this configuration:

<source>
  @type sample
  auto_increment_key count
  tag storage.sample

  <storage>
    @type local
    path storage/sample.json
  </storage>
</source>

The above configuration will save the internal states such as auto_increment_value to storage/sample.json. As a result, you can resume from the next value of previous count when restarting fluentd.
