SyslogAppender should support RFC 5424 -------------------------------------- Key: LBCLASSIC-116 URL: http://jira.qos.ch/browse/LBCLASSIC-116 Project: logback-classic Issue Type: Improvement Components: appender Affects Versions: 0.9.16 Environment: All Reporter: Ralph Goers Assignee: Logback dev list The SyslogAppender supports RFC 3164. RFC 5424 has been released with obsoletes RFC 3164. See http://www.ietf.org/rfc/rfc5424.txt. At the very least the format of the timestamp has been changed. Either the SyslogAppender should be enhanced to comply with RFC 5424 or a new SyslogAppender should be created which does. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.qos.ch/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

SysLog Appender and Line Breaks = :( -------------------------------------- Key: LBCLASSIC-146 URL: http://jira.qos.ch/browse/LBCLASSIC-146 Project: logback-classic Issue Type: Bug Components: appender Environment: Debian 4 Etch, 64 Bit (most likely all enviroments) Reporter: Ingo Siebert Assignee: Logback dev list I'm using the SysLog appender and it works well. But I've problems with line breaks, especially for exceptions. Every strack trace line is written as new SysLog-Entry. Example: Aug 11 20:25:21 192.168.33.11 app2-cas org.osgi.framework.BundleException: The bundle class path entry "patch.jar"..." Aug 11 20:25:21 192.168.33.11 app2-cas ^Iat org.eclipse.osgi.baseadaptor.loader.ClasspathManager.findClassPathEntry(ClasspathManager.java:168) Aug 11 20:25:21 192.168.33.11 app2-cas ^Iat org.eclipse.osgi.baseadaptor.loader.ClasspathManager.buildClasspath(ClasspathManager.java:145) Aug 11 20:25:21 192.168.33.11 app2-cas ^Iat org.eclipse.osgi.baseadaptor.loader.ClasspathManager.initialize(ClasspathManager.java:79) ... That's quire annoying if you want to filter or highlight entries. I think it's major, because there isn't a good workaround to filter/highlight syslog files. I'm using Logback 0.9.13, but I thinks it still exists in the trunk. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.qos.ch/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JIRA] Created: (LBCLASSIC-82) Allow an Appender to be added to a Logger with a Level for more fine grained control of logging output

Allow an Appender to be added to a Logger with a Level for more fine grained control of logging output ------------------------------------------------------------------------------------------------------ Key: LBCLASSIC-82 URL: http://jira.qos.ch/browse/LBCLASSIC-82 Project: logback-classic Issue Type: New Feature Components: appender, joran Environment: N/A Reporter: Robert Elliot Assignee: Logback dev list Priority: Minor Here's my use case: I have an appender, standard.log, whose job is to log major system events such as startup and shutdown, and all problems. I have configured my logger levels very carefully to ensure I get exactly the output I want - in some cases suppressing WARN messages that I know are not a problem by setting the level to ERROR, in some cases allowing INFO messages that let me see important lifecycle events. A simplified example might look like this: root=WARN,standard.log x.y=INFO a=ERROR I have a problem in a couple of parts of the system which means I want to turn on debug logging for that part of the system. I want the output of this to go to a separate appender - debug.log. So now my config looks like this: root=WARN,standard.log x.y=INFO x.y.z=DEBUG,debug.log a=ERROR a.b=DEBUG,debug.log But now I have an issue; all my debug statements are going to standard.log. It is being polluted with a load of information I don't want in it. I have several options: 1) Set additivity to false on x.y.z and a.b. But then any ERROR messages in a.b or INFO or above messages in x.y.z no longer get to standard.log, so this won't do 2) Add a filter of INFO or greater to the standard.log appender But then any INFO and WARN messages in a.b will get to standard.log - and I only want ERROR messages from a and its descendants in there 3) Add a filter of WARN or greater to the standard.log appender Now I still get the WARN messages from a.b that I don't want - and I've lost the INFO messages from x.y that I do want 4) Create two new appenders, standard.log2 for a and standard.log3 for x.y.z. Add a filter to standard.log2 so that it only accepts ERROR. Add a filter to standard.log3 so it only accepts INFO or above. Set additivity to false on a and x.y.z. That works. But it's a huge amount of added configuration, and that would rapidly multiply in a real world setting. 5) Create a custom filter for standard.log which would effectively mirror the logger config by querying the event for its logger and and level. That blows DRY out of the water, of course, and again is a large amount of work for a simple use case. My suggestion to make this easy is to allow Appenders to be added to a Logger with a Level. This solution would operate in parallel with the existing solution, and would not alter the existing behaviour one iota. This would allow me to add debug,log as an appender on a and x.y.z with a level of debug. All debug statements in a and x.y.z & their descendants would be appended to that appender. All statements would also be passed to the "normal" appender and logger hierarchy, so standard.log would still get the same output as before. I have written unit tests for this behaviour and attach a patch fulfilling them; I hope the unit tests flesh out any queries you may have around how this behaves in edge cases. The only change to the public API is a new method addAppender(Appender<LoggingEvent> newAppender, Level level) on Logger. The only change to the config format is allowing an optional level attribute on appender-ref. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.qos.ch/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

SocketAppender is reporting an WARN if connection could not be established. --------------------------------------------------------------------------- Key: LBCLASSIC-156 URL: http://jira.qos.ch/browse/LBCLASSIC-156 Project: logback-classic Issue Type: Improvement Components: appender Affects Versions: 0.917 Environment: java version "1.6.0_15" Java(TM) SE Runtime Environment (build 1.6.0_15-b03-226) Java HotSpot(TM) 64-Bit Server VM (build 14.1-b02-92, mixed mode) Reporter: Joern Huxhorn Assignee: Logback dev list This is a followup to LBCLASSIC-143 which changed the message from ERROR to WARN. The WARN message still results in a dump of the logging status messages. This means that a whole bunch of text is printed to the console whenever Lilith is started - and it looks quite broken due to the stacktrace. So there are two possible solutions for this problem: a) the status is only printed in case of an ERROR b) SocketAppender considers this as an INFO instead of a WARN. I think b) would be reasonable. Other WARNs are much more important, like duplicate logback.xml. Lilith is only an example, btw. We routinely add SocketAppender[localhost] to our console applications. In case of trouble one can simply start Lilith and check the logs that way instead of reading them on the console. The default use-case is executing the app without Lilith, though, so we get the logback status messages on every start - which is quite noisy and annoying. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.qos.ch/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

Need to scan included files --------------------------- Key: LBGENERAL-37 URL: http://jira.qos.ch/browse/LBGENERAL-37 Project: logback-general Issue Type: New Feature Reporter: lala Assignee: Logback dev list Priority: Minor I'm using the following configuration and I'm looking for a method to scan included files. <configuration scan="true" scanPeriod="10 seconds"> <insertFromJNDI env-entry-name="java:comp/env/logback-file" as="logback-file" /> <contextName>lala</contextName> <include file="${logback-file}" /> </configuration> Once scan directive is used, logback is going to rescan this file every 10 seconds whether its modification date has changed. The issue is that I have to overwrite the previous file in order to rescan the target ${logback-file}. I suggest adding an attribute in the configuration marker in order to force logback to scan included files . It could be something like that: <configuration scan="true" scanPeriod="10 seconds" scanIncluded="true"> ..... </configuration> In order to process this task, at each scan logback should memorize the reference to the included files, and their latest modification date. Consequently, every 10 seconds, logback check the whole list of files and rescan the main file if something has changed. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.qos.ch/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

Multiple resource warning is not appropriate for logback-test.xml ----------------------------------------------------------------- Key: LBCLASSIC-130 URL: http://jira.qos.ch/browse/LBCLASSIC-130 Project: logback-classic Issue Type: Improvement Affects Versions: 0.9.14, 0.9.15, 0.9.16 Reporter: Jon Vincent Assignee: Logback dev list Priority: Minor When LBCLASSIC-85 was fixed, it also applied to logback-test.xml. Unfortunately, some IDEs (such as Eclipse) include the test classpath for all modules in a multi-module project -- which means that it's nearly impossible to avoid having multiple logback-test.xml files on the classpath if one project depends on another when running tests in Eclipse. Every test in the project will therefore emit this warning when run from the IDE. Is it possible to have the ContextInitializer only emit this warning for logback.xml, and not logback-test.xml? This would avoid a spurious/unactionable warning for developers using Eclipse. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.qos.ch/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
