Filter sent to betterstack does not seem to be working

[artyrcheek]

I am trying to filter out logs for our /up endpoint by following these docs

config.logtail.filter_sent_to_better_stack do |log_entry|
  # Filter out logs from the /up endpoint
  log_entry.context_snapshot[:http][:path] == "/up"
end
config.logger = Logtail::Logger.create_default_logger(Rails.application.credentials.logtail.source_token)

It doesn't seem to be working 🤔 The docs say "see Logtail::LogEntry for available attributes of the block parameter." The only method I see on the Logtail::LogEntry class is to_hash, should I be checking the HTTP path with to_hash instead?

log_entry.to_hash[:http][:path] == "/up"

Am I missing anything?

Hi @artyrcheek,

Thank you for raising this! Could you share what Ruby and Rails versions are you using? 🙏 Are you using a latest version of logtail-rails gem? This info should help us reproduce the issue faster.

I'm passing this on to the team to take a look soon. I'll make sure to keep you updated here on GitHub.

Thanks again for reaching out.

Hello @artyrcheek and thanks for reporting the issue.

I've tried to reproduce the problem, but I was unsuccessful - the feature behaved as expected.

I've modified the example project according to your description, my config/application.rb looks like this:

require_relative "boot"

require "rails/all"

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

module ExampleProject
  class Application < Rails::Application
    # Initialize configuration defaults for originally generated Rails version.
    config.load_defaults 7.1

    # Configuration for the application, engines, and railties goes here.
    #
    # These settings can be overridden in specific environments using the files
    # in config/environments, which are processed later.
    #
    # config.time_zone = "Central Time (US & Canada)"
    # config.eager_load_paths << Rails.root.join("extras")
    config.logtail.filter_sent_to_better_stack do |log_entry|
      # Filter out logs from the /up endpoint
      log_entry.context_snapshot[:http][:path] == "/up"
    end

    config.logger = Logtail::Logger.create_default_logger("YhLX...REDACTED...hjeu")
  end
end

Then, I installed dependencies via bundle install, started server via PORT=3420 rails server and visited pages 127.0.0.1:3420/, 127.0.0.1:3420/up, and 127.0.0.1:3420/down.

My Live Tail then looks like this (notice the /up request missing):

I even made sure to use the same dependencies:

Tool	Version
Ruby	3.1.2
Rails	7.1.1
logtail-rails	0.2.6
logtail-rack	0.2.4
logtail	0.1.12

Could you please take a look and see whether you'd modified the config/application.rb similarly as above?

Do you see any errors in your app logs?

Could you please make a screenshot of the logs in Live Tail you're trying to filter out? With expanded JSON similar to the screenshot above? 🙏 My thinking is that you might not have active HTTP context, fields are differently named, or the endpoint contains a directory (such as /check/up).

Could you maybe retry your setup in the example project?

Thanks for further details! 🙌
