As of June 2011, the official documentation states As shall become clear, the syntax of logback configuration files is extremely flexible. As such, it is not possible specify the allowed syntax with a DTD file or an XML Schema. There was a brief thread on the topic, but didn’t seem to go anywhere.
This is a rehashed version my answer to the question “Best practices for using Markers in SLF4J/Logback”. Markers can be used to color or mark a single log statement. What you do with these colors, i.e. markers, is entirely up to you. However, two patterns seem to be common for marker usage. Triggering: Some appender … Read more
First, as @darioo said: MDC is used for associating multiple events with few “entities” [Markers] are used for “special” events that you want to have filtered from usual ones So your assertion that You want to use MDC for this. Markers are for highlighting “special” events–filtering, if you will–rather than “slicing”. For example, you might … Read more
Try this: import org.slf4j.LoggerFactory; import ch.qos.logback.classic.Level; import ch.qos.logback.classic.Logger; Logger root = (Logger)LoggerFactory.getLogger(org.slf4j.Logger.ROOT_LOGGER_NAME); root.setLevel(Level.INFO); Note that you can also tell logback to periodically scan your config file like this: <configuration scan=”true” scanPeriod=”30 seconds” > … </configuration>
It’s very possible to do something like this in logback. Here’s an example configuration: <?xml version=”1.0″?> <configuration> <appender name=”FILE” class=”ch.qos.logback.core.FileAppender”> <file>logfile.log</file> <append>true</append> <encoder> <pattern>%-4relative [%thread] %-5level %logger{35} – %msg %n</pattern> </encoder> </appender> <appender name=”ANALYTICS-FILE” class=”ch.qos.logback.core.FileAppender”> <file>analytics.log</file> <append>true</append> <encoder> <pattern>%-4relative [%thread] %-5level %logger{35} – %msg %n</pattern> </encoder> </appender> <!– additivity=false ensures analytics data only goes to … Read more
Logback natively implements the SLF4J API. This means that if you are using logback, you are actually using the SLF4J API. You could theoretically use the internals of the logback API directly for logging, but that is highly discouraged. All logback documentation and examples on loggers are written in terms of the SLF4J API. So … Read more
I believe this would be the simplest solution: <configuration> <contextName>selenium-plugin</contextName> <!– Logging configuration –> <appender name=”STDOUT” class=”ch.qos.logback.core.ConsoleAppender”> <Target>System.out</Target> <filter class=”ch.qos.logback.classic.filter.LevelFilter”> <level>INFO</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> <encoder> <pattern>[%d{yyyy-MM-dd HH:mm:ss.SSS}] [%level] %msg%n</pattern> </encoder> </appender> <appender name=”STDERR” class=”ch.qos.logback.core.ConsoleAppender”> <Target>System.err</Target> <filter class=”ch.qos.logback.classic.filter.LevelFilter”> <level>ERROR</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> <encoder> <pattern>[%d{yyyy-MM-dd HH:mm:ss.SSS}] [%level] [%thread] %logger{10} [%file:%line] %msg%n</pattern> </encoder> </appender> <root level=”INFO”> <appender-ref ref=”STDOUT”/> … Read more
If you set the debug attribute of the configuration element to true, you will get all status information to the console. If this is your problem, just set it to false or remove it. If you have any configuration problems of level WARN or above, you will also get all status information logged to the … Read more
Yes, this is a common problem I’ve run into as well. There are a few workarounds (like manually setting it, as described), but ideally you want a solution that Sets the MDC consistently; Avoids tacit bugs where the MDC is incorrect but you don’t know it; and Minimizes changes to how you use thread pools … Read more
I mostly build large scale, high availability type systems, so my answer is biased towards looking at it from a production support standpoint; that said, we assign roughly as follows: error: the system is in distress, customers are probably being affected (or will soon be) and the fix probably requires human intervention. The “2AM rule” … Read more
