- .. _monitor_kafka_extension:
- Monitoring Kafka storage
- ============================
- The Monitor Kafka storage extension allows to track the requests made against a GeoServer instance
- in an `Apache Kafka <https://kafka.apache.org/>`_ topic, as opposed to keeping the data in memory for a short time, or
- logging it on a audit file.

- :Limitations:
- * Message keys are not supported. This means that the messages will be distributed in a round robbin
- fashion between the partitions.
- * The extension tries to connect and describe the topic at startup, if the topic does not exist or the connection
- cannot be established the extension will fail to start and disable itself. Subsequent requests to
- this instance will not be logged. The timeout for the describe command is set to 10 seconds.
- * The only used serialization format is avro. Avro might be used in other extensions like GeoMesa where a conflict with
- the version of kafka-avro library might be possible.
- :Permissions:
- The Kafka extension needs the following permissions on the Kafka topic in order to work:
- - DESCRIBE
- - WRITE
