Full list of EntityTopicOperatorSpec schema properties

Configures the Topic Operator.

The Topic Operator has its own preconfigured loggers:

LoggerDescriptionDefault Level

rootLogger

Default logger for all classes

INFO

jetty

Logs HTTP server activity

INFO

The Topic Operator uses the Apache log4j2 logger implementation. Use the logging property to configure loggers and logger levels.

You can set log levels using either the inline or external logging configuration types.

Specify loggers and levels directly in the custom resource for inline configuration:

Example inline logging configuration

apiVersion: kafka.strimzi.io/v1beta2
kind: Kafka
metadata:
  name: my-cluster
  annotations:
    strimzi.io/node-pools: enabled
    strimzi.io/kraft: enabled
spec:
  kafka:
    # ...
  entityOperator:
    # ...
    topicOperator:
      watchedNamespace: my-topic-namespace
      reconciliationIntervalMs: 60000
      logging:
        type: inline
        loggers:
          rootLogger.level: INFO
          logger.jetty.level: WARN
  # ...

You can define additional loggers by specifying the full class or package name using logger.<name>.name. For example, to configure more detailed logging for the Topic Operator inline:

Example custom inline loggers

# ...
logger.top.name: io.strimzi.operator.topic
1 

logger.top.level: DEBUG
2 

logger.toc.name: io.strimzi.operator.topic.TopicOperator
3 

logger.toc.level: TRACE
4

1
Creates a logger for the topic package.
2
Sets the logging level for the topic package.
3
Creates a logger for the TopicOperator class.
4
Sets the logging level for the TopicOperator class.

Alternatively, you can reference an external ConfigMap containing a complete log4j2.properties file that defines your own log4j2 configuration, including loggers, appenders, and layout configuration:

Example external logging configuration

apiVersion: kafka.strimzi.io/v1beta2
kind: Kafka
metadata:
  name: my-cluster
  annotations:
    strimzi.io/node-pools: enabled
    strimzi.io/kraft: enabled
spec:
  kafka:
    # ...
  entityOperator:
    # ...
    topicOperator:
      watchedNamespace: my-topic-namespace
      reconciliationIntervalMs: 60000
      logging:
        type: external
        valueFrom:
          configMapKeyRef:
            # name and key are mandatory
            name: customConfigMap
            key: log4j2.properties
  # ...

Garbage collector (GC)

Garbage collector logging can also be enabled (or disabled) using the jvmOptions property.
