td-agentログにエラーが出て、bufferファイルが残る場合がある。
bufferファイルの中身を調べたい場合。
yum eraseしただけでは色々ゴミが残っていた。

fluentd v0.12以降かつ、forwardプラグイン使用時に「require_ack_response」を付ける事で、ログの欠損を抑える

2015-05-22現在、デフォルトでインストールされるtd-agentが2.x系に変わっている。
互換性が無いためリポジトリのパスが変わっている。
1.x系を使いたい場合、以下のように手動でbaseurlを変更するとインストールできる
sudo vi /etc/yum.repos.d/td.repo ---- baseurl=http://packages.treasure-data.com/redhat/$basearch ---- sudo yum clean all sudo yum install td-agent-1.1.19-0.x86_64
echo '{"key":"message"}' | /usr/lib64/fluent/ruby/bin/fluent-cat debug.tag -h revice-td-agent-host
