I'm also looking for advice on this.
If you run your configuration through crm configure verify, it will let you know what are the recommended minimum timeouts. Your timeouts are really too short. As for intervals, that depends on your requirements/resources/expectations. Just note that the shorter the interval, the more computing resources your nodes will devote to monitoring. > It's not clear to me what an interval > would do on a start / stop operation? Nothing. Due to XML schema limitations they have to be present, but they should always be set to 0. Can't comment further on the configuration.
