Inherit Tags

[chancefeick]

Use :inherit_tags option introduced in librato/librato-rack#65 to inherit default tags (service, environment,host) for automatic instrumentation.

Tag inheritance is also applicable to custom instrumentation. Here’s a few examples:

Librato.increment 'user.signup'
# => {:host=>"ip-10-0-0-4.ec2.internal"}

Librato.increment 'user.signup', tags: { plan: 'developer' }
#=> {:plan=>"developer"}

Librato.increment 'user.signup', tags: { plan: 'developer' }, inherit_tags: true
# => {:host=>"ip-10-0-0-4.ec2.internal", :plan=>"developer"}

Merge into #123. Requires librato/librato-rack#65.
