# "WARN -- : Instrumentation: <X> failed to install" is most

# OTEL_RUBY_INSTRUMENTATION_<X>_ENABLED=false

#
|

# For example, PostgreSQL and Redis produce a lot of child spans
|
|
# in the course of this application doing its business. To turn
|
|
# them off, set the env vars below, but recognize that you will
|
|
# be missing details about what particular calls to the
|
|
# datastores are slow.
