Chapter 50. EntityUserOperatorSpec schema reference Used in: EntityOperatorSpec Full list of EntityUserOperatorSpec schema properties Configures the User Operator. 50.1. logging The User Operator has a configurable logger: rootLogger.level The User Operator uses the Apache log4j2 logger implementation. Use the logging property in the entityOperator.userOperator field of the Kafka resource to configure loggers and logger levels. You can set the log levels by specifying the logger and level directly (inline) or use a custom (external) ConfigMap. If a ConfigMap is used, you set logging.valueFrom.configMapKeyRef.name property to the name of the ConfigMap containing the external logging configuration. Inside the ConfigMap, the logging configuration is described using log4j2.properties . Both logging.valueFrom.configMapKeyRef.name and logging.valueFrom.configMapKeyRef.key properties are mandatory. A ConfigMap using the exact logging configuration specified is created with the custom resource when the Cluster Operator is running, then recreated after each reconciliation. If you do not specify a custom ConfigMap, default logging settings are used. If a specific logger value is not set, upper-level logger settings are inherited for that logger. For more information about log levels, see Apache logging services . Here we see examples of inline and external logging. The inline logging specifies the rootLogger.level . You can also set log levels for specific classes or loggers by adding them to the loggers property. Inline logging apiVersion: kafka.strimzi.io/v1beta2 kind: Kafka metadata: name: my-cluster spec: kafka: # ... zookeeper: # ... entityOperator: # ... userOperator: watchedNamespace: my-topic-namespace reconciliationIntervalSeconds: 60 logging: type: inline loggers: rootLogger.level: INFO logger.uop.name: io.strimzi.operator.user 1 logger.uop.level: DEBUG 2 logger.abstractcache.name: io.strimzi.operator.user.operator.cache.AbstractCache 3 logger.abstractcache.level: TRACE 4 logger.jetty.level: DEBUG 5 # ... 1 Creates a logger for the user package. 2 Sets the logging level for the user package. 3 Creates a logger for the AbstractCache class. 4 Sets the logging level for the AbstractCache class. 5 Changes the logging level for the default jetty logger. The jetty logger is part of the logging configuration provided with Streams for Apache Kafka. By default, it is set to INFO . Note When investigating an issue with the operator, it's usually sufficient to change the rootLogger to DEBUG to get more detailed logs. However, keep in mind that setting the log level to DEBUG may result in a large amount of log output and may have performance implications. External logging apiVersion: kafka.strimzi.io/v1beta2 kind: Kafka metadata: name: my-cluster spec: kafka: # ... zookeeper: # ... entityOperator: # ... userOperator: watchedNamespace: my-topic-namespace reconciliationIntervalSeconds: 60 logging: type: external valueFrom: configMapKeyRef: name: customConfigMap key: user-operator-log4j2.properties # ... Garbage collector (GC) Garbage collector logging can also be enabled (or disabled) using the jvmOptions property . 50.2. EntityUserOperatorSpec schema properties Property Property type Description watchedNamespace string The namespace the User Operator should watch. image string The image to use for the User Operator. reconciliationIntervalSeconds integer Interval between periodic reconciliations. zookeeperSessionTimeoutSeconds integer The zookeeperSessionTimeoutSeconds property has been deprecated. This property has been deprecated because ZooKeeper is not used anymore by the User Operator. Timeout for the ZooKeeper session. secretPrefix string The prefix that will be added to the KafkaUser name to be used as the Secret name. livenessProbe Probe Pod liveness checking. readinessProbe Probe Pod readiness checking. resources ResourceRequirements CPU and memory resources to reserve. logging InlineLogging , ExternalLogging Logging configuration. jvmOptions JvmOptions JVM Options for pods.
