ansible callbacks
ansible callbacks编辑callbacks.py脚本文件(/usr/lib/python2.6/site-packages/ansible-1.8-py2.6.egg/ansible/callbacks.py)
找到类AggregateStats
在AggregateStats中有2个方法，

def compute(self, runner_results, setup=False, poll=False, ignore_errors=False):
''' walk through all results and increment stats '''
for (host, value) in runner_results.get('contacted', {}).iteritems():
if not ignore_errors and (('failed' in value and bool(value['failed'])) or
('failed_when_result' in value and ] or ['rc' in value and value['rc'] != 0])):
self._increment('failures', host)
elif 'skipped' in value and bool(value['skipped']):
self._increment('skipped', host)
elif 'changed' in value and bool(value['changed']):
if not setup and not poll:
self._increment('changed', host)
self._increment('ok', host)
else:
if not poll or ('finished' in value and bool(value['finished'])):
self._increment('ok', host)
for (host, value) in runner_results.get('dark', {}).iteritems():
self._increment('dark', host)
global lazy_out
lazy_out = runner_results
print lazy_out.get('contacted').get(host).get('stdout')
def summarize(self, host):
''' return information about a particular host '''
return dict(
ok = self.ok.get(host, 0),
failures = self.failures.get(host, 0),
unreachable = self.dark.get(host,0),
changed = self.changed.get(host, 0),
skipped = self.skipped.get(host, 0),
#haha = lazy_out.values().values()['stdout'],
haha = lazy_out.get('contacted').get(host).get('stdout')
)
其中的runner_results中有我们想要的输出结果。
使用global将lazy_out设置为runner_results
然后在summarize方法中调用lazy_out，使用字典的get方法进行取值。
值得一提的是，如果你的playbook里面有多个task，sumarize只返回最后一个。
