Public Instance Methods
Returns the attributes hash representing the Redis
client context found in the optional context or the current context if none is provided.
@param [optional Context] context The context to lookup the current
attributes hash. Defaults to Context.current
# File lib/opentelemetry/instrumentation/redis.rb, line 26 def attributes(context = nil) context ||= Context.current context.value(CURRENT_ATTRIBUTES_HASH) || {} end
Returns a context containing the merged attributes hash, derived from the optional parent context, or the current context if one was not provided.
@param [optional Context] context The context to use as the parent for
the returned context
# File lib/opentelemetry/instrumentation/redis.rb, line 36 def context_with_attributes(attributes_hash, parent_context: Context.current) attributes_hash = attributes(parent_context).merge(attributes_hash) parent_context.set_value(CURRENT_ATTRIBUTES_HASH, attributes_hash) end
Activates/deactivates the merged attributes hash within the current Context, which makes the “current attributes hash” available implicitly.
On exit, the attributes hash that was active before calling this method will be reactivated.
@param [Span] span the span to activate @yield [Hash, Context] yields attributes hash and a context containing the
attributes hash to the block.
