A confusing question about Monit

[章旭东]

Hi, I have a question about Monit. Here is this scenario: Monit is running on server A and monitoring a service B. At one time, service B went down and Monit sent alert. Then, server A went down so Monit process stopped. Then, service B went up. In the end, server A went up. When starting Monit, Monit checked the status of service B and found it up so it simply did not do anything. But in fact, service B was from down status to up status, so Monit should send alert. Could you please kindly teach me how to solve this? Thanks.
