What are the different log files in WSO2 ESB?

Question

In WSO2 ESB I have several log files in the repository/log directory. What are the differences and which one should I use for the daily control if everything is alright?

Answer 1

Well I experienced now the following:

• http_access_xxxx.log: Contains log of any HTTP access (in my case only the carbon admin jsp)
• wso2carbon.log: Contains the real log output of the Application Server (most important one)
• wso2carbon-trace-messages.log: Always empty - don't know what it is for
• wso2-esb-error.log: Lists all WARNING and ERROR message from the wso2carbon.log again here - no INFO or DEBUG messages
• wso2-esb-service.log: Contains all logs that have been made with the "Log" Mediator in Synapse Proxies or Sequences
• wso2-esb-trace.log: Always empty - don't know what it is for

Well just add your monitoring on the wso2carbon.log file and you have everything essential.

WSO2carbon.log contains most of the logs about the server (service logs , error logs etc.) You can use it as the main log for maintaining. http_acces log contain about Apache access logs. Serivce logs have individual ESB services logs.
