something funky is going on w/ the 0.1.0 gem version that is on rubygems:

➜  cardstock git:(main) ✗ bundle install                                         
Fetching gem metadata from https://rubygems.org/.........
Resolving dependencies...
Downloading opentelemetry-exporter-otlp-logs-0.1.0 revealed dependencies not in the API or the lockfile (opentelemetry-logs-api
(~> 0.1), opentelemetry-logs-sdk (~> 0.1)).
Running `bundle update opentelemetry-exporter-otlp-logs` should fix the problem.
➜  cardstock git:(main) ✗ bundle update opentelemetry-exporter-otlp-logs         
Could not find gem 'opentelemetry-exporter-otlp-logs'.

I was able to get otel logs integrated with rails. Am I the first to do this? Should I document somewhere?

@adenta, I'm having the same issue. I inadvertently solved it locally at some point, but after clearing my gems, I'm having the same problem again.

It appears to be RubyGems; I can gem install opentelemetry-exporter-otlp-logs but bundle install only works if I point directly to GitHub in my Gemfile:

# Pull logs API from the logs_api folder
gem 'opentelemetry-logs-api',
    git: 'https://github.com/open-telemetry/opentelemetry-ruby.git',
    branch: 'main',
    glob: 'logs_api/*.gemspec'

# Pull logs SDK from the logs_sdk folder
gem 'opentelemetry-logs-sdk',
    git: 'https://github.com/open-telemetry/opentelemetry-ruby.git',
    branch: 'main',
    glob: 'logs_sdk/*.gemspec'

# Pull the OTLP logs exporter from the exporter/otlp-logs folder
gem 'opentelemetry-exporter-otlp-logs',
    git: 'https://github.com/open-telemetry/opentelemetry-ruby.git',
    branch: 'main',
    glob: 'exporter/otlp-logs/*.gemspec'

Hi @iancoralogix, thanks for your comment. I'm able to reproduce this issue. Taking a look and will be back with more soon.

Hi, I tried out the opentelemetry-logs gems and I was wondering if it is possible to combine it with Rails, currently it is required to use the on_emit method to send logs but there isn't an example or docs on how to combine it with the default logging on Rails.

Thanks!

@kayla should know where my example implementation is, I think I left it in a community post or something On Sun, Feb 2, 2025 at 12:31 PM Diego del Valle @.***> wrote:

I would love to use the Logs Exporter in my Rails app. But I find 0 documentation, no README, no "how to use it" comments in the code. I am lost
