No idea about logstash and graylog integration. Maybe you will find some help in logstash forum. But, can you confirm the _p values are not 0 in output? E.g. run topbeat with -e -v -d 'publish' to see the json being generated (or enable console output in topbeat.yml).
It's taken from another Linux server's data upload on Graylog.
I believe some of us like me, we dont understand what are the explanations of these fields. You will remark some of these fields values are constant. I never see a value for _p fields. P means percentage ? If yes, why cant see a value even it's not a Windows server.
I believe, somebody should write a good explanation for eeach of these fields.
