RailsログLTSV対応(LTSV Logger + UUID)

概要

• RailsログのLTSV対応するのに既存のgem使ってみた
• 条件 : UUIDを出せること
• 使ってみたのは

1. ltsv-logger
2. logger-ltsv

結論

• 非常に簡単に使える
• どちらもあまりメンテされてなさそう
• 色々やりたければ自前の方がいいかも

使ってみた

1 ltsv-logger

• https://github.com/terut/ltsv-logger

config/environments/development.rb

    # ltsv-logger
    config.log_tags = [ :uuid ]
    config.logger = ActiveSupport::TaggedLogging.new(LTSV::Logger.open("log/development.log"))
