logstash:错误，无法检索cgroup信息 [英] logstash: Error, cannot retrieve cgroups information

问题描述

我正在尝试使用特定的配置文件运行logstash:

I'm trying to run logstash using specific config file:

$ /usr/share/logstash/bin/logstash --debug -f $HOME/conf.d/conf2.conf --path.settings /etc/logstash

我收到此错误:

[2018-06-26T15:00:41,046][DEBUG][logstash.pipeline        ] Pushing flush onto pipeline {:pipeline_id=>"main", :thread=>"#<Thread:0x6556cab@/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:247 sleep>"}

您对此有任何想法吗?
