$ docker run -it --entrypoint=/bin/bash ruby:2.4.0
$ apt-get update; apt-get install -y sudo
$ curl -L https://toolbelt.treasuredata.com/sh/install-debian-jessie-td-agent3.sh | sh
$ gem install fluent-plugin-prometheus
$ td-agent

This works with latest plugin version, fluentd 1.12.1 and ruby 2.4. There must be something wrong in your install

I am not using docker, why? td-agent3 package already has embedded ruby 2.4.0. Yet fluent-plugin-prometheus tries to load ripper module which was deprecated in ruby 1.9 AFAIK.

Maybe, the problem is your td-agent is old: https://github.com/treasure-data/omnibus-td-agent/issues/242

jze1 commented 3 years ago

The agent is maybe old but the embedded ruby is still 2.4.0.

AntoineC44 commented 3 years ago

@jze1 docker was for reproducibility from a ruby 2.4.0 base image, seems to work launching directly fluentd, and with td agent 3 version provided (which embeds ruby 2.4.5) seems also to work
