Hello zhangxudong,
yes, this is the way how monit work.
Service B is up an running before monitor is up, you can't get an alert
therefore.

In general, I use monit to start all the applications.
In a short form, I start/handle the processes monitored by monit via monit.
I run monit on server A, all the time server A is going down the
processes are stopped. After server A is back again monit start the
processes handled by monit (after monit is up "monit start all" start
all processes).
This is my way, Martin Pala can give you a more detailed answer.
