fluent-plugin-better-timestamp

fluentd plugin to store timestamp with millisecond to elasticsearch

fluentd uses unixtime as 'time' and fluent-plugin-elasticsearch inserts the 'time' to elasticsearch as @timestamp. Therefore, it's not easy to store more detailed time data like millisec. But fluentd-plugin-elasticsearch provides another way to store timestamp to elasticsearch. if record has '@timestamp', that will be stored in elasticsearh.

this plugin works as a filter that creates '@timestamp' with proper format from 'time' and one more field which have 'msec' data

gem install fluent-plugin-better-timestamp

'better-timestamp' plugin has only 3 config parameters

• tag
• msec_key - specifies the key name for msec (default: msec)
• timestamp_key - specifies the key name for output (default: @timestamp)

<source>
  type tail

  format /^(?<time>\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}).(?<msec>\d{3}) .....
  ...
  tag log
