Examples of com.dianping.cat.message.Trace

com.dianping.cat.message.Trace

Trace is used to log anything for trace message info happens at a specific time. Such as an debug or info message.

All CAT message will be constructed as a message tree and send to back-end for further analysis, and for monitoring. Only Transaction can be a tree node, all other message will be the tree leaf.　The transaction without other messages nested is an atomic transaction.
