我对/etc/init.d下的cluster资源脚本增加了打log的功能，观察2次rgmanager检测status的间隔，发现是40s。
然后根据man clurgmgrd的说法，

status_poll_interval - This defines the amount of time, in seconds, rgmanager waits between resource tree scans for status checks. Decreasing this value may improve rgmanager's ability to detect failures in services, but at a cost of decreased performance and increased system utilization. The default is 10 seconds.

对status_pool_interval做了配置，
这个数改为5的时候，实际间隔是35s
这个数改为3对时候，实际间隔是33s

另外的那30s是怎么出来的？如何缩短？man里面提到的‘resource tree scans'是什么东东？请不吝赐教。

补充信息：
设置了status_pool_interval参数，发现实际上的间隔似乎是30+status_pool_interval, 那个30s不知道在哪里出来的。

比如       <rm status_poll_interval="3">时，间隔是33s
