I'm taking a quick look at JBC-related logging in the AS from 1.4.0.SP1, and had the following comments: 1) 08-10 11:14:59,421 DEBUG [org.jboss.cache.TreeCache] viewAccepted(): [JBOSS-33102AB21:1551|0] [JBOSS-33102AB21:1551] Having this at INFO is pretty important; this is critical info for support cases. 2) 2006-08-10 11:14:56,984 INFO [org.jboss.cache.factories.InterceptorChainFactory] interceptor chain is: .... Should this be INFO? I don't mind if it is, just wanted to check. 3) 2006-08-10 11:14:59,484 DEBUG [org.jboss.cache.buddyreplication.BuddyManager] New buddy group: BuddyGroup: ..... Having this at INFO would be good as well. There's a lot of INFO logging from NextMemberBuddyLocator. I think that's fine for now, while we shake down that code. Perhaps some optimization in later releases (e.g. check the # of view members and skip some steps that will obviously fail; track whether the view size is increasing to detect when cluster is just forming and log at lower levels while that is going on).
