saltstack中的event为我们提供了跟踪salt执行的的机制。 下面是一个简单实用salt event的例子：
import salt.utils.event event = salt.utils.event.MasterEvent('/var/run/salt/master') for eachevent in event.iter_events(full=True): print eachevent print "------"上面一段程序会简单的打印saltstack执行的salt情况，当然，我们可以把执行日志保存到文件或者数据库。使用方式是首先执行上面的脚本：
python monitor_event.py
然后在另外一个终端中执行一个salt命令，例如: salt '*' cmd.run ifconfig 这样前面的event监控脚本就会打印出执行任务的情况。 输出类似：
