| == Configuring loggers for Policy Logic |
| |
| The logging for the logic inside a policy (task logic, task selection logic, state finalizer logic) can be configured separate from standard logging. |
| The logger for policy logic is `org.onap.policy.apex.executionlogging`. |
| The following example defines |
| |
| - a new appender for standard out using a very simple pattern (simply the actual message) |
| - a logger for policy logic to standard out using the new appender and the already described file appender. |
| |
| [source%nowrap,xml] |
| ---- |
| <appender name="POLICY_APPENDER_STDOUT" class="ch.qos.logback.core.ConsoleAppender"> |
| <encoder> |
| <pattern>policy: %msg\n</pattern> |
| </encoder> |
| </appender> |
| |
| <logger name="org.onap.policy.apex.executionlogging" level="info" additivity="false"> |
| <appender-ref ref="POLICY_APPENDER_STDOUT" /> |
| <appender-ref ref="FILE" /> |
| </logger> |
| |
| ---- |
| |
| It is also possible to use specific logging for parts of policy logic. |
| The following example defines a logger for task logic. |
| |
| [source%nowrap,xml] |
| ---- |
| <logger name="org.onap.policy.apex.executionlogging.TaskExecutionLogging" level="TRACE" additivity="false"> |
| <appender-ref ref="POLICY_APPENDER_STDOUT" /> |
| </logger> |
| ---- |
