FluentdをHTTP経由でコンフィグロードして起動させるワンライナーhack

fluentd -i "include http://localhost:3000/fluentd.conf" -c /dev/null

or

curl -s -S http://localhost:3000/fluentd.conf | fluentd -i - -c /dev/null

前者の方法は-HUP送っても再読み込みしてくれる。 後者の方法だと-HUP送るとcurl経由のconfigが消えるので注意。

fluentd 0.10.42

webサーバが落ちてたらどうなるの?

fluentd -i "include http://localhost:3000/fluentd.conf" -c /dev/null

で起動させた後、Webサーバを落としてfluentdにHUPを送ってたらfluentdはerror吐いて落ちたので、最悪プロセス監視とかログ監視で気づける。
