Each logging event has the following attributes:
| Event type | Each generated event has a type attribute. |
| Message parameters | Used for formatting the message |
| eventParameters | A map of custom event parameters that can be used by custom event listeners |
| throwable | Exception associated with an event |
| severity | (OFF, FATAL, ERROR, WARN, INFO, FINE) - Severity of the event |
| Category name | Specifies logger (used by logging frameworks such as java.util.logging or Log4J). |
| Message text | User message |
LogEvent severities:
| Level | Explanation |
| OFF | The OFF level is intended to turn off logging. |
| FINE | FINE designates fine-grained informational events that are most useful for debugging an application. |
| INFO | INFO designates informational messages that highlight the progress of the application at the coarse-grained level. |
| WARN | The WARN level designates potentially harmful situations. |
| ERROR | The ERROR severity designates error events that may allow the application to continue running. |
| FATAL | The FATAL level designates very severe error events that will presumably cause the application to abort. |
Each WSO2 SOA Enablement Server log event is extended from com.systinet.wasp.monitoring.events.WaspLogEvent. All custom log events must either extend this class or implement org.systinet.monitoring.Event.
