nagios監(jiān)控服務(wù)出現(xiàn)FLAPPING狀態(tài)時(shí)無法發(fā)出郵件報(bào)警信息

1.服務(wù)出現(xiàn)FLAPPING狀態(tài)時(shí)無法發(fā)出郵件報(bào)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(shù)起作用，當(dāng)服務(wù)在兩種狀態(tài)之間頻繁切換時(shí)，為避免不停的發(fā)送報(bào)警，此參數(shù)用于抑制報(bào)警
