Where is fluent-gem for td-agent 2.0.2 on OSX?

[Michael Holroyd]

Installed the experimental td-agent v2.0.2 for OSX but the /usr/lib/fluent folder doesn't exist. Is there a different way to install plugins?

[Michael Holroyd]

Found it in /opt/td-agent/embedded/lib/ruby/gems/2.1.0/gems/fluentd-0.10.50/bin/fluent-gem

I hadn't seen https://groups.google.com/forum/#!searchin/fluentd/td-agent$202.0/fluentd/JXR2hmHDCZU/op71iV5utUEJ

Someone should update the changelog -- I had looked at this but it doesn't include 2.* changes: http://docs.treasuredata.com/articles/td-agent-changelog

Further sadness:

meekohi ~$ /opt/td-agent/embedded/bin/fluent-gem

/opt/td-agent/embedded/lib/ruby/2.1.0/rubygems/dependency.rb:298:in `to_specs': Could not find 'fluentd' (>= 0) among 14 total gem(s) (Gem::LoadError)

from /opt/td-agent/embedded/lib/ruby/2.1.0/rubygems/dependency.rb:309:in `to_spec'

from /opt/td-agent/embedded/lib/ruby/2.1.0/rubygems/core_ext/kernel_gem.rb:53:in `gem'

from /opt/td-agent/embedded/bin/fluent-gem:22:in `<main>'

Doesn't seem like 2.0.2 is actually using the embedded version of ruby. After installing the elasticsearch plugin via

/opt/td-agent/embedded/lib/ruby/gems/2.1.0/gems/fluentd-0.10.50/bin/fluent-gem install fluent-plugin-elastisearch

The process continues to crash with

2014-06-27 15:06:30 -0400 [error]: config error file="/etc/td-agent/td-agent.conf" error="Unknown output plugin 'elasticsearch'. Run 'gem search -rd fluent-plugin' to find plugins"

and I don't see the newly installed gem listed in the logs.

That's strange.

I and my colleagues don't hit such problem.

My result is below.

Do you use rvm?

I do indeed use rvm - currently on rvm 1.25.27 (stable), could that be causing an issue?

td-agent sometimes hits this problem on RVM environment.

See this thread: https://groups.google.com/forum/#!searchin/fluentd/rvm/fluentd/ekODAaJuS9M/mwvFsYh8Z70J

Could you try "fluent-gem install" after disabled RVM or

add "env GEM_HOME=/opt/td-agent/embedded/lib/ruby/gems/2.1.0/ GEM_PATH=/opt/td-agent/embedded/lib/ruby/gems/2.1.0/" to "fluent-gem install".
