nagios監控服務出現FLAPPING狀態時無法發出郵件報警信息

1.服務出現FLAPPING狀態時無法發出郵件報警信息
[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參數起作用，當服務在兩種狀態之間頻繁切換時，為避免不停的發送報警，此參數用于抑制報警
