Logging | docs.camunda.org (2023)

This page provides information about logging in Camunda.

Most Camunda modules, including the Camunda engine, use slf4j as logging “facade”. This allows users to direct logging output to the logging “backend” of their choice, such as logback or log4j.

When installing Camunda as a shared process engine in an application server, Camunda logging is pre-configured.

On all application servers except Wildfly, logging is pre-configured using the slf4j-jdk14 bridge.This means that Camunda effectively re-directs all its logging to Java Util Logging.Both SLF4J API and the slf4j-jdk14 bridge are available in a shared classpath which means that they are available in the classpath of all applications deployed on these servers.

On Wildfly, logging is directed to the JBoss logging infrastructure. The SLF4J API is not available in the classpath of custom applications by default.

Adding a Logging Backend for Embedded Use

When using the Camunda Maven modules in a custom application, only the slf4j API is pulled in transitively.If you do not provide any backend, nothing will actually be logged.

In the following, we provide two alternative examples of how to set up logging. See the SLF4J Documentation for more detailed information on how to add a logging backend.

Example Using Java Util Logging

If you do not care for a specific logging backend, the simplest option is to direct logging to Java Util Logging by adding the followingmaven dependency:

<dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-jdk14</artifactId> <version>1.7.26</version></dependency>

Example Using Logback

For a more sophisticated logging setup we recommend using Logback. To do so, the following steps are necessary:

Add the logback dependency

<dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.1.2</version></dependency>

Add a file named logback.xml. Example configuration:

<configuration> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <!-- encoders are assigned the type ch.qos.logback.classic.encoder.PatternLayoutEncoder by default --> <encoder> <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern> </encoder> </appender> <!-- camunda --> <logger name="org.camunda" level="info" /> <!-- common dependencies --> <logger name="org.apache.ibatis" level="info" /> <logger name="javax.activation" level="info" /> <logger name="org.springframework" level="info" /> <root level="debug"> <appender-ref ref="STDOUT" /> </root></configuration>

Also make sure to make mybatis use SLF4J as logger by adding


somewhere in your setup code.

Process Data Context

In order to provide details on the current execution context of log statements,we set process execution-specific data in the Mapped Diagnostic Context (MDC).

The process data is held in the MDC for the time of process execution and removed from it after the execution context is successfully left.In case of arising exceptions upon execution, the data is kept in the MDC until the calling context,i.e. the JobExecutor or the surrounding command, finished its logging.

The keys at which the properties are accessible in the MDC can be defined in theprocess engine configuration.

In order to access the MDC data, you need to adjust the logging pattern of your logging configuration.An example using Logback could look as follows

<configuration> ... <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} context:[%X] - %msg%n</pattern> </encoder> </appender> ...</configuration>

By adding the context:[%X] to your configuration, all values that are present in the MDC at the time the log statement is created will be displayed.Please refer to the manual of your logging framework for further information on how to access the MDC, e.g. the Logback documentation.

Process Engine

The process engine logs on the following categories

Logger Description
org.camunda.bpm.application logs details for the deployed process application on the engine
org.camunda.bpm.container logs container operations in the engine
org.camunda.bpm.engine.bpmn.behavior logs operations performed on bpmn activities
org.camunda.bpm.engine.bpmn.parser logs events that occur during the parsing of the bpmn models
org.camunda.bpm.engine.cfg logs process engine configuration's initialization details
org.camunda.bpm.engine.cmd logs the start and end of all commands that the engine performs
org.camunda.bpm.engine.cmmn.behavior logs exceptions that occur during cmmn execution for incompatible cmmn behavior
org.camunda.bpm.engine.cmmn.operation logs exceptions during execution of cmmn operations
org.camunda.bpm.engine.cmmn.transformer logs cmmn transformer operations performed by the engine
org.camunda.bpm.engine.context command context logs including executing atomic operations and bpmn stack traces during exceptions
You can override the default DEBUG log level for bpmn stack traces, see the Logging level parameters section.
org.camunda.bpm.engine.core logs engine's core operations, e.g. performing atomic operations
org.camunda.bpm.engine.dmn logs exceptions that occur during decision evaluation
org.camunda.bpm.dmn.feel logs events that occur during decision evaluation with the JUEL FEEL Engine
org.camunda.bpm.dmn.feel.scala logs events that occur during decision evaluation with the Scala FEEL Engine
org.camunda.feel.FeelEngine logs events that occur during expression evaluation with the Scala FEEL Engine
org.camunda.bpm.engine.externaltask logger for the external task
org.camunda.bpm.engine.identity logger of the IdentityService, for example logs information whether a user is locked
org.camunda.bpm.engine.incident logs details during incident processing
org.camunda.bpm.engine.jobexecutor logs operations performed by the job executor, such as job acquisition
org.camunda.bpm.engine.metrics logs details regarding the engine metrics
org.camunda.bpm.engine.migration logs exceptions that occur during process migration
org.camunda.bpm.engine.persistence logs the identity of all entities that the engine inserts/deletes/updates in the database
org.camunda.bpm.engine.plugin.admin logs authorization details for administrators if AdministratorAuthorizationPlugin is enabled
org.camunda.bpm.engine.pvm logs the Process Virtual Machine (PVM) operations, e.g. entering/leaving an activity, creating/destroying a scope
org.camunda.bpm.engine.rest.exception logs the exceptions thrown in the REST API
org.camunda.bpm.engine.script logs script processing details, e.g. evaluating, compiling
org.camunda.bpm.engine.security logs exceptions that occur during password hashing
org.camunda.bpm.engine.telemetry logs details about the sent information and error details in case the data couldn't be collected or sent
org.camunda.bpm.engine.test logger used in the engine tests
org.camunda.bpm.engine.tx logs transaction details, e.g. commits and rollbacks
org.camunda.bpm.engine.util logs engine utility operations like xml parsing, reading streams, class loading issues, parsing intervals/duration, etc.
org.camunda.bpm.webapp logs events from the Camunda web apps (Cockpit, Tasklist, and Admin), like user-initiated log in and log out events and cache validation time information.

By default, the engine output contains logs with level ERROR, WARNING, and INFO. To enable more log output, e.g. for the purpose of debugging, configure the level of a logger to DEBUG or TRACE.

Heads Up!

The output of loggers can change with newer Camunda versions.

Heads Up!

In Tomcat, logging is handled by java.util.logging via Tomcat’s JULI implementation. Note that the log levels DEBUG and TRACE are called FINE and FINEST in this environment.

When to use engine loggers?

Increasing the level of some engine loggers can provide more insights to analyze the engine behavior.Please be aware, some of the loggers can create large amounts of output when changing their level to DEBUG or TRACE.In this section, common scenarios are listed where increasing the engine log levels can be helpful.

Database statements

To check the database statements performed by the engine in most of the cases, it will be sufficient to increase the level of org.camunda.bpm.engine.persistence and org.camunda.bpm.engine.impl.persistence.entity loggers.On level DEBUG, they log all SQL statements with their parameters. When set to TRACE, the results of the statements are logged in addition. Note if a query has many results, the log output will be large.

However, some of the statements are not covered by only these two loggers. The full list to see all of the engine database statements is:

  • org.camunda.bpm.engine.persistence
  • org.camunda.bpm.engine.impl.persistence.entity
  • org.camunda.bpm.engine.impl.history.event
  • org.camunda.bpm.engine.impl.batch
  • org.camunda.bpm.engine.impl.cmmn.entity
  • org.camunda.bpm.engine.impl.dmn.entity.repository
  • org.camunda.bpm.engine.history

Here is an example of how the server log will look like:

25-Nov-2019 15:15:57.870 FINE [thread-1] o.c.c.l.BaseLogger.logDebug ENGINE-03006 Cache state after flush: [ PERSISTENT GroupEntity[development]]25-Nov-2019 15:15:57.871 FINE [thread-1] o.c.c.l.BaseLogger.logDebug ENGINE-03009 SQL operation: 'INSERT'; Entity: 'AuthorizationEntity[id=19ac0d96-0f8e-11ea-8b01-e4a7a094a9d6]'25-Nov-2019 15:15:57.871 FINE [thread-1] o.a.i.l.j.BaseJdbcLogger.debug ==> Preparing: insert into ACT_RU_AUTHORIZATION ( ID_, TYPE_, GROUP_ID_, USER_ID_, RESOURCE_TYPE_, RESOURCE_ID_, PERMS_, REV_ ) values ( ?, ?, ?, ?, ?, ?, ?, 1 )25-Nov-2019 15:15:57.872 FINE [thread-1] o.a.i.l.j.BaseJdbcLogger.debug ==> Parameters: 19ac0d96-0f8e-11ea-8b01-e4a7a094a9d6(String), 1(Integer), development(String), null, 2(Integer), development(String), 2(Integer)25-Nov-2019 15:17:17.075 FINE [thread-2] o.a.i.l.j.BaseJdbcLogger.debug ==> Preparing: update ACT_ID_GROUP set REV_ = ?, NAME_ = ?, TYPE_ = ? where ID_ = ? and REV_ = ?25-Nov-2019 15:17:17.076 FINE [thread-2] o.a.i.l.j.BaseJdbcLogger.debug ==> Parameters: 2(Integer), Dev-Department(String), DEV(String), development(String), 1(Integer)

To enable the logging for a specific database entity, please provide the namespace of the MyBatis mapper (all mappers). Usually it is the full class name of that entity, e.g.:

  • org.camunda.bpm.engine.impl.batch.BatchEntity
  • org.camunda.bpm.engine.impl.persistence.entity.JobEntity
  • org.camunda.bpm.engine.impl.persistence.entity.VariableInstanceEntity

For further information please visit the MyBatis documentation about logging..

Diagnosing Job Execution

To investigate the Job Execution behavior, as a start switch the level of the following loggers to DEBUG:

  • org.camunda.bpm.engine.impl.persistence.entity.JobEntity - logs the job execution statements
  • org.camunda.bpm.engine.jobexecutor - further job execution logs such as job acquisition and execution operations
  • org.camunda.bpm.engine.cmd - the start/end of commands will help to determinate in which command the job is being executed

The server log will contain logs similar to:

Diagnosing Deadlocks

The engine logging will provide further insights in case of deadlock issues by increasing the level of the command and the persistence loggers.First, determine the resource involved in the deadlock, then try to narrow down, which are the two transactions blocking each other:

  • org.camunda.bpm.engine.persistence - the persistence logger will log all the identity of engine entities to find the involved resources causing the deadlock
  • org.camunda.bpm.engine.cmd - the command output will help to determinate the scope of the involved transactions which are causing the deadlock

When the issue occurs for a specific entity (e.g. VariableInstance), consider enabling the logger of that entity as well (org.camunda.bpm.engine.impl.persistence.entity.VariableInstanceEntity).Then the output will include the statements of these entities to observe the changes which are performed.Here is a sample of what traces the server log file will contain when increasing the level of these loggers.
