However, I think that admin which wants to automate processing as much as possible exists. > The only thing I'm not sure is if the admin really want to do this?

When a resource failed, I think that the score of the resource becomes less than 0. When the resource was not able to start in all nodes in the site, I think that score becomes less than 0 in all nodes. I want to judge the state that a resource was not able to operate from this score. When a ticket does not become grant, the score of the resource becomes less than 0. Therefore, I want to monitor the resource while a ticket becomes grant. > > Well, I think you raised another using scenario which I has not thought > of before;) And I agree with you to setup such a daemon to do this work > if the admin need. I want you to confirm it again when you were completed.
