1.服务出现FLAPPING状态时无法发出邮件报警信息
[1409537279] SERVICE ALERT: rs-07;Memory;CRITICAL;HARD;2;Connection refused by host
[1409537279] SERVICE FLAPPING ALERT: rs-07;Memory;STARTED; Service appears to have started flapping (28.2% change >= 20.0% threshold)

2.原因：flap_detection_enabled参数起作用，当服务在两种状态之间频繁切换时，为避免不停的发送报警，此参数用于抑制报警

define service{
        name                            generic-service
        active_checks_enabled           1

        event_handler_enabled           1
        flap_detection_enabled          0        <--当服务在多个状态直接频繁切换时，抑制触发监控报警。使之不生效
