Logs getting mixed in log file
by Sumit Anvekar 24 Jan '14

24 Jan '14

Hi, I have 2 web applications which use log back for logging. I'm referring to the logback jars in both applications using a single shared library. each application has its own log file. Most of the logs work fine (i.e, they go to the required log files) but some others get mixed up, e.g. consider applications as A and B, sometime logs from application A are present in application B log files. I'm not sure what is causing this. Let me know if i'm missing anything. Sumit.

Introducing Whisper - a suppression capable logback appender
by Karthik Abram 13 Jan '14

13 Jan '14

Hello Logback users, I wanted to make you all aware of a new Logback appender that I have released called Whisper. Whisper is a delegating appender that can suppress error messages when they exceed a configured threshold. During the suppression period, Whisper will send you a digest of messages that were suppressed. Once the frequency drops back to normal, message flow will continue as usual. 1. Where do I find it? http://eclecticlogic.github.io/whisper/ 2. What's the main use case for this? In conjunction with SMTP appender for error emails to prevent error email span when things go bad.3. What kind of license? Apache 2.04. Does Whisper suppress all messages? No, it only suppresses those messages that have exceeded the threshold. 5. What if my messages are similar but only vary by a couple of parameters? If you use the SLF4j api and use the parameterized log message format, then Whisper will suppress across parameterized messages. ThanksKA

ReconfigureOnChangeFilter does not reuse context properties?
by Mike Müller 09 Jan '14

09 Jan '14

Hi I'm using a config file wich looks like this: <?xml version="1.0" encoding="UTF-8"?> <configuration scan="true" scanPeriod="60 seconds" > <appender name="cms" class="ch.qos.logback.core.FileAppender"> <file>${pathToLogs}mysign-cms.log</file> <Append>false</Append> <encoder> <pattern>%d %30.30t %-5p %45.45c - %m%n</pattern> </encoder> </appender> <appender name="R" class="ch.qos.logback.core.FileAppender"> <file>${pathToLogs}log.log</file> <Append>false</Append> <encoder> <pattern>%d %30.30t %-5p %45.45c - %m%n</pattern> </encoder> </appender> <logger name="ch.mysign" additivity="false" level="INFO"> <appender-ref ref="cms"/> </logger> <root level="WARN"> <appender-ref ref="R"/> </root> </configuration> The parameter ${pathToLogs} comes from the following code: LoggerContext context = (LoggerContext) LoggerFactory.getILoggerFactory(); try { JoranConfigurator configurator = new JoranConfigurator(); configurator.setContext( context ); context.reset(); context.putProperty( "pathToLog", "my-path-to-the-external-logs" ); configurator.doConfigure("my-logback-config.xml" ); } catch ( JoranException je ) { System.out.println( je.getMessage() ); } If I change the config file, the property "pathToLog" gets lost. Is this the same issue as descibed in [1]? If yes, is it a problem to reuse the context or at least the properties of the old context? [1] http://jira.qos.ch/browse/LOGBACK-592 best regards Mike

SyslogAppender
by Jason Dusek 02 Jan '14

02 Jan '14

Hi All, I am trying to use the SyslogAppender. One problem I am having is that the program name is absent, and the PID seems to be "main". I assume this is because the program name is generically set to "main" and the PID is actually omitted. I wanted to confirm this by browsing the source but I am having some trouble understanding the underlying details. In particular, what does this code do? // http://logback.qos.ch/xref/ch/qos/logback/classic/net/SyslogAppender.html#1… layout.getInstanceConverterMap().put("syslogStart", SyslogStartConverter.class.getName()); I am not as familiar with Java idioms as I could be; and I've lost the trail at around "syslogStart". I would like to try working off of SyslogAppenderBase to get a syslog appender that understands UNIX sockets. Is that something the project would welcome? -- Jason Dusek

allow configuration of max connections in ReceiverBase
by Sebastian Gröbler 20 Dec '13

20 Dec '13

Hi, in the context of remote socket logging the maximum amount of possible socket connections is defined through the max pool size of the context’s executor service. It would be great if the amount of socket connections would be configurable. Further I think the amount of socket connections should be independent from the context's executor service, meaning the ReceiverBase should have it's own executor service. If there is an agreement, I would be happy to provide a pull request for this. Cheers! Sebastian

Main roller: FixedWindowRollingPolicy; trigger: TimeBasedRollingPolicy
by Felipe 11 Dec '13

11 Dec '13

Hey friends! Greetings from Chile. I'd like to achieve the following: 1. I want my main rollingPolicy to be FixedWindowRollingPolicy. This way, my main logging file will always be named the same way and backup files will by rolling. 2. I want the triggeringPolicy to be TimeBasedRollingPolicy, so it rolls every day at 04:00 AM. I couldn't find a way to achieve this and I only saw examples of SizeBasedTriggeringPolicy, which is not my desired triggeringPolicy. I couldn't find a parameter for TimeBasedRollingPolicy and besides of that it seems to require fileNamePattern. Is there any way to achieve this? Thanks in advance! Best regards. -- Felipe

Hi Everyone :-) i've many troubles getting my FileAppender creating Logfiles. The Logfile itself is created, but it's always empty. I don't know what else i can do??!
