附件不使用logstash输出slack插件

Question

我的Grok过滤器是这样的：

 grok {
        match => ["message", "%{TIMESTAMP_ISO8601} Thread:'(?<thread>[^']+)' Level:'%{LOGLEVEL:log-level}' Message:%{GREEDYDATA:information}"]

这在输出中工作正常：

slack
        {
           url => "https://hooks.slack.com/services/XXXXXXXX/XXXXXXXX/xxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
           format => "%{log-level} at %{@timestamp} on %{type} \n\n Message: %{information}"
        }

附件不起作用，\n也不会破坏线条，它只是在Slack中显示为\ n

我的错误消息日志是多行的大块文本，所以我真的想做这样的事情，这是不行的：

slack
        {
           url => "https://hooks.slack.com/services/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"
           format => "%{log-level} at %{@timestamp} on %{type} with IP:%{host}"
           attachments => "Message: %{information}"
        }
