User-filtered logging - can be done?
by Y M 20 Dec '11

20 Dec '11

Hello, I'm trying to obtain a certain logging configuration, but so far I'm unsuccessful. I've read through the Logback manual, but I don't know if I can do what I want. It is a web application, and my objective is to enable a finer logging level for specific users, getting written to a specific log file, allowing better debugging directly in production environment. When needed, someone will set a tuned XML config using JMX to enable logging for the duration of the tests/data gathering (JMX is working fine). This is the relevant part of my logback.xml file: <configuration debug="true"> ... <appender name="FILTERED" class="ch.qos.logback.core.rolling.RollingFileAppender"> <filter class="com.sample.project.UserFilter">  <level>DEBUG</level> <user>123456</user> </filter> ... </appender> <logger name="com.sample.project"> <appender-ref ref="FILTERED" /> </logger> <logger name="com.sample.legacy" additivity="false"> <appender-ref ref="LEGACY" /> </logger> <root level="WARN"> <appender-ref ref="STANDARD" /> </root> </configuration> With this config, I intend to have:- WARN+ level at root;- events from legacy project tree only on 'LEGACY' (working fine);- 'FILTERED' logging only DEBUG+ events from user '123456' under 'com.sample.project', while its level ramains at WARN (not OK). Sample:getLogger("com.sample.abc").warn("..."); //logged to STANDARDgetLogger("com.sample.abc").debug("..."); //not loggedgetLogger("com.sample.legacy").warn("..."); //logged to LEGACYgetLogger("com.sample.project").warn("..."); //logged to STANDARD; also logged to FILTERED if user is 123456getLogger("com.sample.project").debug("..."); //logged to FILTERED if user is 123456 As I tested, a 'logger.debug()' from the desired user does not get logged, the filter is not even called, and I suspect that the effective WARN level denies the event before reaching my filter (I hoped for the other way around). If I set DEBUG on 'com.sample.project', 'FILTERED' will get the correct logging, but 'STANDARD' will be flooded with DEBUG+ logging from 'com.sample.project'. And disabling additivity on it removes all logging belonging to this hierarchy from 'STANDARD'. So, I see Logback is working properly, my desired logging seems to be against the standard architecture. But is there a way to archive the described effect?I was thinking of a TurboFilter, allowing lower level events from selected users (not tested yet), but I'm not sure the effective level would kick in first, also it wouldn't do the desired logging separation between 'STANDARD' and 'FILTERED' anyway. As another approach, maybe this would require a custom Logger class, handling specific appenders in a special way. Unfortunately, I have no idea if I can plug in custom Loggers, and also not sure how to code it (Logger class source is quite complex in a quick look). Sorry if it wasn't clear, I'm not sure how to present the situation. I can provide further details, if needed.Any help is welcome. If someone could show me which way to follow, maybe classes or methods to extend, I'd be grateful. Many thanks!

Problems with DBAppender / JNDI / JBoss 7 / OracleDB
by Henning Diederichs 19 Dec '11

19 Dec '11

Hi there, I’m trying to log into Oracle database tables using DBAppender and JNDIConnectionSource. I created the needed tables for logging as mentioned in documentation. I want to use connection pooling and the JNDI variant for getting the pool. Here’s my configuration: -JBoss 7.0.2 (the complete one, not the web profile) -Oracle DB 11g -logback-classic 0.9.29 -ojdbc 11.2.0.2.0 I configured the following things: In JBoss: -A new module for Oracle JDBC drivers -A new connection pool using Oracle JDBC drivers in the modules segment of JBoss In standalone.xml: <datasource jndi-name="java:/myLog" pool-name="myLogPool" enabled="true" jta="true" use-java-context="true" use-ccm="true"> <connection-url> jdbc:oracle:thin:@127.0.0.1:1521:orcl </connection-url> <driver> oracle </driver> <transaction-isolation> TRANSACTION_READ_COMMITTED </transaction-isolation> <pool> <prefill> true </prefill> <use-strict-min> false </use-strict-min> <flush-strategy> FailingConnectionOnly </flush-strategy> </pool> <security> <user-name> log </user-name> <password> secretPassw0rd </password> </security> </datasource> -logback-classic.jar and it's dependencies are being shipped with my .ear file. In logback.xml: ... <appender name="DBAppender" class="ch.qos.logback.classic.db.DBAppender"> <connectionSource class="ch.qos.logback.core.db.JNDIConnectionSource"> <param name="jndiLocation" value="java:/myLog" /> </connectionSource> </appender> ... <root> <appender-ref ref="DBAppender" /> </root> I have also configured a RollingFileAppender and a ConsoleAppender. They both work fine on my JBoss. In the server.log from JBoss you can see that he successfully published my data source myLog under java:/myLog. I can't see any problems occurring due to logging from JBoss. No problems with logging via logback are mentioned. But when my application starts logging, the entries are logged to console and the file appender, but nothing is written to the database. I have a second connection pool configured in JBoss for my application. That one is working fine. I can't figure out what the problem is. Please help me. Regards, Henning

Transport protocol for SMTPAppender
by kalgon 16 Dec '11

16 Dec '11

Hi, is it possible to define what protocol (mail.transport.protocol) to use with SMTPAppender other than through System properties which are global? Logging important info which must be sent by mail must be part of my tests and for that purpose, I've made a MockTransport that I would like to use. Thanks, Xavier -- View this message in context: http://old.nabble.com/Transport-protocol-for-SMTPAppender-tp32986718p329867… Sent from the Logback User mailing list archive at Nabble.com.

logback rollover within a certain period of time
by MOO MIK KI 15 Dec '11

15 Dec '11

Dear sir/madam, I am a university student trying to create a software related to my coursework and 1 of the requirements is that the output of logback file will rollover to new files every 5 minutes. I am unable to find a solution to this and i tried to use the periodictimebasedfilenamingandtriggeringpolicy. I cannot get any msg out of it. Here is my configuration in the xml when i use periodictimebasedfilenamingandtriggeringpolicy : <?xml version="1.0" encoding="UTF-8"?> <configuration> <appender name="rsms.rolling" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>d:\\log\\RSMS\\RSMS.txt</file> <ImmediateFlush>true</ImmediateFlush> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">  <fileNamePattern>d:\\log\\RSMS\\BK\\RSMS-%d{yyyy-MM-dd_HHmm}.%i.txt</fileNamePattern> </rollingPolicy> <triggeringPolicy class="ch.qos.logback.core.rolling.PeriodicTimeBasedFileNamingAndTriggeringPolicy"> <period>600</period> </triggeringPolicy> <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern>%d{yyyyMMdd HHmmss.SSS} [%-5level]%msg%n</Pattern> </layout> </appender> <logger name="lol" level="debug" additivity="false"> <appender-ref ref="rsms.rolling" /> </logger> </configuration>

Problem with fileNamePattern for daily rollover
by Christophe Roudet 14 Dec '11

14 Dec '11

Hello, I'd like to set up a daily rollover: <appender name="monitoringAppender" class="ch.qos.logback.core.rolling.RollingFileAppender"> <append>true</append> <file>log/monitoring.log</file> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">  <fileNamePattern>log/monitoring-%d{EE}.log</fileNamePattern> <maxHistory>7</maxHistory> </rollingPolicy> <encoder> <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} - %msg%n</pattern> </encoder> </appender> but when I set up the fileNamePattern with %d{EE} archives are not created. Using the default pattern %d{yyyy-MM-dd} works fine. Am I doing something wrong? Thanks, Christophe

Enable Debugging Mode Programmatically?
by juminoz 14 Dec '11

14 Dec '11

I was wondering if there is a way to enable debug mode programmatically. Since I'm not allowed to use configuration file, I'm currently configure everything programmatically. Recently, I ran into an issue where RollingFileAppender stop writing to file though FileAppender works perfectly fine. In fact, RollingFileAppender was also working last week and nothing that I'm aware of has changed since. Please let me know if there is a way to enable debug since doing it using configuration file (logback.xml) doesn't seem to be working.

UnknownHostException when using logback with logback.xml
by Jan Ehrhardt 13 Dec '11

13 Dec '11

Hi, when I use logback without a logback.xml, everything works fine, but when I add a logback.xml file, I get an UnknownHostException. This happens in the ch.qos.logback.core.util.ContextUtil class, when InetAddress.getLocalHost() is called. In our environment, there is no hostname mapping available to the JVM, so the JVM cannot find one. So why does logback require the IP at this point? Regards Jan Ehrhardt

Documentation/FAQ - Typo/error in variable substitution example?
by Cyril DANGERVILLE 07 Dec '11

07 Dec '11

Hello, I just tried the example given for variable substitution in the FAQ with logback 1.0.0: http://logback.qos.ch/faq.html#sharedConfiguration And it seems the "context.reset();" line is not in the right place. If I use the same code as in the example, I got this (I added a few lines of code at the end to print the filename that should be changed after doConfigure()): --BEGIN CODE-- LoggerContext context = (LoggerContext) LoggerFactory.getILoggerFactory(); // context.reset(); // This works! // property of the LoggerContext context.putProperty("application-name", "killerapp"); JoranConfigurator jc = new JoranConfigurator(); jc.setContext(context); context.reset(); // override default configuration. This does not work (no variable substitution)! try { jc.doConfigure(Test.class.getResourceAsStream("/logback.xml")); } catch (JoranException e1) { throw new RuntimeException(e1); } Appender<ILoggingEvent> appender = context.getLogger("mylogger").getAppender("FILE"); String filename = ((RollingFileAppender<ILoggingEvent>) appender).getFile(); System.out.println("filename = " + filename); --END CODE-- --OUTPUT-- filename = d:/users/logs/application-name_IS_UNDEFINED_error.log --END OUTPUT-- Now, if I uncomment line 2: "// context.reset(); // This works!" and comment out " context.reset(); // override default configuration...", I get what I want: --OUTPUT-- filename = d:/users/logs/killerapp_error.log --END OUTPUT-- In short, it makes a more sense and it works if context.reset() is done before setting the property. Otherwise, I guess the property map is cleared with the reset if done after. Am I correct? In which case, the FAQ should be fixed accordingly Thanks.
