Question

尝试在Windows上运行logstash 5时：

C：\发展\工作空间\ logstash＆GT; C：\开发\ SOFTWARE \ logstash-5.1.2 \ BIN \ logstash.bat -f robot-log.js

它出现以下错误：

Could not find log4j2 configuration at path /Development/Software/logstash-5.1.2/config/log4j2.properties. Using default config which logs to console
15:03:53.667 [[main]-pipeline-manager] INFO  logstash.filters.multiline - Grok loading patterns from file {:path=>"C:/Development/Software/logstash-5.1.2/vendor/bundle/jruby/1.9/gems/logstash-patterns-core-4.0.2/patterns/aws"}
15:03:53.684 [[main]-pipeline-manager] INFO  logstash.filters.multiline - Grok loading patterns from file {:path=>"C:/Development/Software/logstash-5.1.2/vendor/bundle/jruby/1.9/gems/logstash-patterns-core-4.0.2/patterns/bacula"}
15:03:53.693 [[main]-pipeline-manager] INFO  logstash.filters.multiline - Grok loading patterns from file ...

该文件实际存在于目录中。为什么logstash无法找到它？

注意：我最初虽然这是Ruby使用Linux路径分隔符的问题。但是，正如@Stefan在下面的评论中指出的那样，Ruby甚至在Windows上接受了Linux样式路径

这似乎是最新版本的logstash中的一个错误。在logger.rb下，它有以下代码：

def self.initialize(config_location)
        @@config_mutex.synchronize do
          if @@logging_context.nil?
            file_path = URI(config_location).path
            if ::File.exists?(file_path)
              logs_location = java.lang.System.getProperty("ls.logs")
              puts "Sending Logstash's logs to #{logs_location} which is now configured via log4j2.properties"
              @@logging_context = Configurator.initialize(nil, config_location)
            else
              # fall back to default config
              puts "Could not find log4j2 configuration at path #{file_path}. Using default config which logs to console"
              @@logging_context = Configurator.initialize(DefaultConfiguration.new)
            end
          end
        end
      end

对URI.path的调用似乎有问题，因为根据documentation，当输入为/posts时，它会返回http://foo.com/posts?id=30&limit=5#time=1305298413

我不是Ruby程序员所以我不知道为什么logstash devs在这里使用它。但只需将file_path = URI(config_location).path替换为file_path = config_location即可解决问题。

C:\Development\workspace\logstash>C:\Development\Software\logstash-5.1.2\bin\logstash.bat -f robot-log.js

Logstash无法找到log4j2.properties配置文件
