+## Logging and Error Handling 
+
+OpenTelemetry uses [java.util.logging](https://docs.oracle.com/javase/7/docs/api/java/util/logging/package-summary.html)
+to log information about OpenTelemetry, including errors and warnings about misconfigurations or failures exporting 
+data. 
+
+By default, log messages are handled by the root handler in your application. If you have not 
+installed a custom root handler for your application, logs of level `INFO` or higher are sent to the console by default. 
+
+You may 
+want to change the behavior of the logger for OpenTelemetry. For example, you can reduce the logging level 
+to output additional information when debugging, increase the level for a particular class to ignore errors coming 
+from that class, or install a custom handler or filter to run custom code whenever OpenTelemetry logs
+a particular message. 
+
+### Examples
+
+```properties
+## Turn off all OpenTelemetry logging 
+io.opentelemetry.level = OFF
+```
+
+```properties
+## Turn off logging for just the BatchSpanProcessor 
+io.opentelemetry.sdk.trace.export.BatchSpanProcessor.level = OFF
+```
+
+```properties
+## Log "FINE" messages for help in debugging 
+io.opentelemetry.level = FINE
+
+## Sets the default ConsoleHandler's logger's level 
+## Note this impacts the logging outside of OpenTelemetry as well 
+java.util.logging.ConsoleHandler.level = FINE
+
+```
+
+For more fine-grained control and special case handling, custom handlers and filters can be specified
+with code. 
+
+```java
+// Custom filter which does not log errors that come from the export
+public class IgnoreExportErrorsFilter implements Filter {
+
+ public boolean isLoggable(LogRecord record) {
+    return !record.getMessage().contains("Exception thrown by the export");
+ }
+}
+```
+
+```properties
+## Registering the custom filter on the BatchSpanProcessor
+io.opentelemetry.sdk.trace.export.BatchSpanProcessor = io.opentelemetry.extensions.logging.IgnoreExportErrorsFilter
+```
