keepalivedのヘルスチェック その３

LVS

定期的に500を返すようにしてwgetを使う。

    real_server 192.168.11.15 80 {
        weight 1
        MISC_CHECK {
          misc_path "wget --spider -t 3 -T 3 -O - http://192.168.11.15/keepalived_HTTP_GET"
          misc_timeout 10
        }
    }
}



192.168.11.13 - - [13/Dec/2009:13:30:50 JST] "HEAD /keepalived_HTTP_GET HTTP/1.0" 200 0

192.168.11.13 - - [13/Dec/2009:13:30:52 JST] "HEAD /keepalived_HTTP_GET HTTP/1.0" 500 0

192.168.11.13 - - [13/Dec/2009:13:30:54 JST] "HEAD /keepalived_HTTP_GET HTTP/1.0" 200 0

…って500が返ると結局、瞬断するのか。
