logback

How is logback's “prudent mode” implemented?

由 泪湿孤枕 提交于 2020-01-04 12:16:54
问题 The prudent mode in logback serializes IO operations between all JVMs writing to the same file, potentially running on different hosts. In other logging frameworks, logging to a central TCP (or JMS) appender seems to be the only solution if output from many loggers should go to the same file. As I am using a Delphi library which is based on log4j and also can not log to the same file from different instances of the same applications (on a terminal server), it would be interesting to know how

Scala Play framework: logger pattern for displaying file and line

由 北战南征 提交于 2020-01-04 06:32:28
问题 I've a simple scala app (not using Play MVC framework) but that uses play.api.Logger I'm trying to figure out the pattern I need to add to include the File and Line where the log was done. This was the logback.xml I was using from the start: <configuration> <conversionRule conversionWord="coloredLevel" converterClass="play.api.Logger$ColoredLevel"/> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%date %-16coloredLevel %message %n</pattern> </encoder> <

multiple root loggers with logback conditionals

由 一笑奈何 提交于 2020-01-04 04:05:32
问题 referring to: Logback's Configuration my configuration can contain ...at most one <root> element... but then later in the same doc, when discussing conditionals, I see this: <configuration debug="true"> <if condition='property("HOSTNAME").contains("torino")'> <then> <appender name="CON" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%d %-5level %logger{35} - %msg %n</pattern> </encoder> </appender> <root> <------ root logger #1 <appender-ref ref="CON" /> </root> </then> </if>

Grails 3: External Logback.groovy file

由 纵然是瞬间 提交于 2020-01-04 03:54:14
问题 I'm trying to externalize my logback.groovy file by setting the path in my build.gradle file in the bootrun closure: bootRun { if (Environment.currentEnvironment == Environment.PRODUCTION) { jvmArgs = ['-XX:MaxPermSize=2g', '-Xmx2g', '-Dlogging.config=/path/to/config/logback.groovy'] } else { jvmArgs = ['-XX:MaxPermSize=2g', '-Xmx2g'] } } But I am getting: .logback.classic.LoggerContext[default] - Found resource [logback.groovy] at [file:/Users/name/workspace/project/build/resources/main

What's wrong with my logback syslog appender?

由 霸气de小男生 提交于 2020-01-04 01:30:59
问题 I'm trying to get a logback syslog appender working, and I've definitely got something misconfigured. I've created a small sample project which I think should log to syslog, yet it doesn't. I'm sure I'm missing something stupid. Here's the appender from logback.xml: <appender name="SYSLOG" class="ch.qos.logback.classic.net.SyslogAppender"> <syslogHost>localhost</syslogHost> <facility>USER</facility> <suffixPattern>[%thread] %logger %msg</suffixPattern> </appender> I've tried adding the port

Hibernate 4 Wildfly 8 logging not working

由 蓝咒 提交于 2020-01-03 16:12:21
问题 How do I get hibernate 4 to log via logback? I have a war deployed to wildfly 8 final, and I am using slf4j with logback. The logging setup is working 100% in the application with both the console appender and file appender working as intended. Here is what I did to get slf4j + logback working: Excluded the logging subsystem with jboss-deployment-structure.xml in WEB-INF: <?xml version="1.0" encoding="UTF-8"?> <jboss-deployment-structure> <deployment> <exclude-subsystems> <subsystem name=

三、Spring Boot日志 1、日志框架 日志的抽象层：JCL、SLF4J、jboss-logging 日志的实现：Log4j JUL、Log4j2 Logback Spring Boot：底层是Spring、Spring默认是JCL、而Spring Boot选用SLF4j和logback 2、SLF4j 2.1 系统中如何使用 开发的时候，日志记录方法的调用应该调用日志抽象层的方法 首先导入slf4j的jar和logback的jar，可以查看下图 import org . slf4j . Logger ; import org . slf4j . LoggerFactory ; public class HelloWorld { public static void main ( String [ ] args ) { Logger logger = LoggerFactory . getLogger ( HelloWorld . class ) ; logger . info ( "Hello World" ) ; } } 每一个日志都有自己的配置文件，使用slf4j后还是使用日志框架自己本身的配置文件 2.2 多个日志框架统一转成slf4j 如何让系统中所有的日志统一到slf4j 首先将系统的其它日志框架排除 用中间包来替换原来的日志框架 导入slf4j来实现统一框架 2

Adding timestamp to a log file using Logback-test.xml

由 混江龙づ霸主 提交于 2020-01-03 09:11:09
问题 Currently my Spring-boot application logs to a file named: myLog.log , this is working as intended, however I would like the log file to have a timestamp at the end of it and create a new file each time it is ran. I have tried to implement this in my logback-test.xml file shown below, but it is just giving me the filename: myLog.log without a timestamp. How can I fix this? Logback-test.xml: <?xml version="1.0" encoding="UTF-8"?> <configuration> <include resource="org/springframework/boot

Spring @PreDestroy: No logging because Logback stops too soon

由 好久不见. 提交于 2020-01-03 08:25:10
问题 In my project, I am using Logback as logging facility. I have the following class @Component class Test { @PreDestroy public void destroy() { try { ... } catch (Exception e) { LoggerFactory.getLogger(getClass()).error(e.getLocalizedMessage(), e); } } } Now, I undeploy the servlet. When an exception occurs, Logback is not printing the message and stack trace. This is because Logback is cleaning up before the destroy() is called by Spring. When undeploying the servlet, this is the first (and

Logs sent to console using logback configuration in java app, not visible in Kubernetes using kubectl logs

由 拜拜、爱过 提交于 2020-01-02 23:04:50
问题 I read in kubernetes docs somewhere that kubernetes reads application logs from stdout and stderror in pods. I created a new application and configured it to send logs to a remote splunk hec endpoint (using splunk-logback jars) and at the same time to console. So by default, the console logs in logback should go to System.out, which should then be visible using kubectl logs . But it's not happening in my application. my logback file: <?xml version="1.0" encoding="UTF-8"?> <configuration>
