Hopefully this is enough to get you started. I've been meaning to write up a
blog post on this, so I might try and get that done soon.
You need to set up some stub objects so Python knows what to do with them,
like:
class PuppetReport(yaml.YAMLObject):
yaml_tag = u'!ruby/object:Puppet::Transaction::Report'
def __init__(self, host, logs, metrics, records, time):
self.host = host
self.logs = logs
self.metrics = metrics
self.records = records
self.time = time
class PuppetLog(yaml.YAMLObject):
yaml_tag = u'!ruby/object:Puppet::Util::Log'
def __init__(self, source, message, tags, time, level):
self.source = source
self.message = message
self.tags = tags
self.time = time
self.level = level
class PuppetMetric(yaml.YAMLObject):
yaml_tag = u'!ruby/object:Puppet::Util::Metric'
def __init__(self, values, name, label):
self.values = values
self.name = name
self.label = label
Then when you read the yaml file, Python will
consider !ruby/object:Puppet::Util::Metric to be a PuppetMetric class.
This may not be complete even for these objects, but I tend to just iterate
until I've got all the data I need.
