[QA (Japanese)]td-agentによるWIndowsイベントログのローカルファイルへの出力

[tt001a]

やりたいこと

Windows2012サーバにて、td-agentを使用してWindowsイベントログをローカルのログファイルへ出力する設定を実施したいと考えております。
td-agent.confにローカルのログファイルへ出力するよう設定を記入し、サービスを再起動しましたが、ローカルのログファイルへの出力が実施されません。

環境について

- TD Agent version:4.5.3
- Operating system:Windows Server 2012

出力先のパスに書き込み権限がないため、Fluentdが動作を停止しているようです。

2025-01-21 16:38:55 +0900 [error]: fluent/log.rb:404:error: config error file=
"C:\\opt\\td-agent\\etc\\td-agent\\td-agent.conf" error_class=Fluent::ConfigError 
error="out_file: `c:\\Users\\XXXXX\\Documents\\output_20250117_1.log.20250121_**.log` is not writable"

結論から申し上げますと、特定のユーザー配下のパスを使われようとしていることが原因である可能性が非常に高いです。
ユーザーの配下ではなく、C:\opt\td-agent\配下のパスを利用したり、C:\fluentd-output\のようなディレクトリーを作成して利用してみてください。
もしそれでも上手くいかなかったり、それらができない事情があれば、お気軽にご相談ください。

以下補足です。

fluent-packageやtd-agentのWindows版は、FluentdをWindowsサービスとして動作させます。
この際、Local Systemアカウント権限での動作となり、システム全般への強い権限を持っているはずなのですが、特定ユーザーのディレクトリーにはそれでもアクセスができないケースがあるようです。
