轉換 syslog-ng 3.0？格式為 3.2 格式

剛剛將我的系統重新啟動到此警告

:: Starting Syslog-NG                                                                       [BUSY]
WARNING: Configuration file format is too old, please update it to use the 3.2 format as some constructs might operate inefficiently;
WARNING: the expected message format is being changed for unix-domain transports to improve syslogd compatibity with syslog-ng 3.2. If you are using custom applications which bypass the syslog() API, you might need the 'expect-hostname' flag to get the old behaviour back;

任何人都知道任何關於轉換格式的好資源？我syslog-ng.conf的主要來自Gentoo 安全手冊，因此簡單地使用該.pacnew文件是行不通的

這是我目前的 conf 文件

它可能與 3.2 中的這種變化有關：

• syslog-ng 傳統上期望一個可選的主機名欄位，即使在本地傳輸（例如 /dev/log）上接收到 syslog 消息時也是如此。但是，已知沒有 UNIX 版本包含此欄位。當創建日誌消息的應用程序在其程序名稱欄位中有空格時，這會導致問題。如果配置版本為 3.2，則 unix-stream/unix-dgram/pipe 驅動程序的此行為已更改，並且可以通過使用特定源的顯式“expect-hostname”標誌來恢復。

您收到警告是因為您使用了 unix-stream("/dev/log"); 在你的來源。如果您的本地日誌沒有遇到任何問題，除了將第一行更改為 @version: 3.2 之外，別無他法

如果您的發行版將主機名添加到來自 /dev/log 的日誌消息（他們很少這樣做），則在源中包含 flags(expect-hostname)。
