Input S3 with debug mode (BIG POST)

Elastic Stack Logstash
1

Hello ,
For a couple days I have been working with logstash 6.2 with docker, using the official docker's image for try get S3 file with logs, I'll try describe all the process with lot details, because I can't do get logs with logstash.

1- The following config I have been using to format files, basically I'm using grok filter, previously check it, in the grok tester online (http://grokconstructor.appspot.com)

pipeline.yml

input {
      s3 {
        bucket => "e-api-logs"
        prefix => "api/test/*.txt"
        interval => 30
        access_key_id => "xxxxxxx"
        secret_access_key => "xxxxx"
      }
    }

output {
      if "-grokparsefailure" not in [tags] {
        elasticsearch {
          hosts => ["http://elastic-svc:9200"]
          index => "e-api-%{+YYYY.MM.dd}"
        }
        stdout { codec => rubydebug }
      }
    }

`

Is not necessary show the grok filter because I don't have errors with it.

I ran the docker with logstash in debug mode:

Everything looks good for now, but I have 2 problems, the first I don't have any output (remember it has rubydebug activated) and I have an error in debug mode:

[DEBUG][logstash.instrument.periodicpoller.cgroup] Error, cannot retrieve cgroups information {:exception=>"Errno::ENOENT", :message=>"No such file or directory - /sys/fs/cgroup/cpuacct/kubepods/besteffort/pod00ce1eec-2858-11e8-bc5c-0297d68e3126/5e404648a476ab9f4667f6d09bee669bc939bd8318a227ee6737d8a48c8f5cb8/cpuacct.usage"}

It has repeat at the end of logs.

Any help I'll appreciate, thanks.
