Method: VCAP::Logging.setup_from_config

Defined in:
lib/vcap/logging.rb

.setup_from_config(config = {}) ⇒ Object

Configures the logging infrastructure using a hash parsed from a config file. The config file is expected to contain a section with the following format: logging:

 level: <default_log_level>
  file: <filename>
syslog: <program name to use with the syslog sink>

This interface is limiting, but it should satisfy the majority of our use cases. I’m imagining usage will be something like:

config = YAML.load(<file>)
...
VCAP::Logging.setup_from_config(config[:logging])
