TODO: Delete this and the text above, and describe your gem

install to your td-agent env

td-agent-gem install fluent-plugin-nested-hash-filter

Add config to your td-agent.conf

Filter: just only convert passed hash into flatten key-value pair.

<filter {MATCH_PATTERN}>
  type nested_hash
  connector .
  acts_as_json ["key1", "key2-1.key2-2"]
</filter>

Output: convert passed hash into flatten key-value pair, and rename tag.

<match {MATCH_PATTERN}>
  type       nested_hash
  tag_prefix {PREFIX}
  connector  .
  acts_as_json ["key1", "key2-1.key2-2"]
</match>

tag_prefix is required parameter to add prefix to matched tag name.

connector is optional parameter to connect nested-keys. (default: .) not for tag prefix connection.

acts_as_json is optional parameter to convert string to hash in json format. (default: [] empty)

• ex: matched tag is access.log and tag_prefix is converted., then log will be passed with tag name converted.access.log.
