Module: Kirei::Logging

Defined in:

lib/kirei/logging/logger.rb,
lib/kirei/logging/level.rb,
lib/kirei/logging/metric.rb

Overview

Example Usage:

Kirei::Logging::Logger.call(
 level: Kirei::Logging::Level::INFO,
 label: "Request started",
 meta: {
   key: "value",
 },
)

You can define a custom log transformer to transform the logline:

Kirei::App.config.log_transformer = Proc.new { _1 }

By default, "meta" is flattened, and sensitive values are masked using sane defaults that you can finetune via Kirei::App.config.sensitive_keys.

You can also build on top of the provided log transformer:

Kirei::App.config.log_transformer = Proc.new do |meta|
 flattened_meta = Kirei::Logging::Logger.flatten_hash_and_mask_sensitive_values(meta)
 # Do something with the flattened meta
 flattened_meta.map { _1.to_json }
end

NOTE:

* The log transformer must return an array of strings to allow emitting multiple lines per log event.
* Whenever possible, key names follow OpenTelemetry Semantic Conventions, https://opentelemetry.io/docs/concepts/semantic-conventions/
