Examples of com.dianping.cat.message.Event

com.dianping.cat.message.Event

Event is used to log anything interesting happens at a specific time. Such as an exception thrown, a review added by user, a new user registered, an user logged into the system etc.

However, if it could be failure, or last for a long time, such as a remote API call, database call or search engine call etc. It should be logged as a Transaction

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.
