Kafka Cluster
Connect kPow to Apache Kafka®
The ENVIRONMENT_NAME variable provides a UI friendly name for your Kafka cluster.
Requirements
kPow requires at least one configured Kafka cluster to operate.
When configuring Multi-Cluster installations the first cluster configured is your Primary Cluster and contains all the snapshot, metrics, and audit metadata for the installation.
A Kafka cluster can have multiple associated Schema registries and/or Kafka connect clusters.
Compatibility
kPow is compatible with Apache Kafka 1.0+.
kPow has been tested and is compatible with Apache Kafka, Amazon MSK, Red Had AMQ Streams, Aiven Managed Kafka, Instaclustr Managed Kafka, Confluent Platform and Confluent Cloud, Azure Event Hubs*, Redpanda.
*Some disk related metrics and telemetry are not available when using kPow Azure Event Hubs.
FIPS
kPow is capable of integrating with FIPS compliant Kafka clusters.

Access Control
User permissions to Kafka cluster resources are defined by Cluster actions.​
AWS IAM Integration
kPow supports IAM Access Control for AWS MSK.
Simply set your kPow connection fields appropriately, e.g.
1
SSL_TRUSTSTORE_LOCATION=<PATH_TO_TRUST_STORE_FILE>
2
SECURITY_PROTOCOL=SASL_SSL
3
SASL_MECHANISM=AWS_MSK_IAM
4
SASL_JAAS_CONFIG=software.amazon.msk.auth.iam.IAMLoginModule required;
5
SASL_CLIENT_CALLBACK_HANDLER_CLASS=software.amazon.msk.auth.iam.IAMClientCallbackHandler
Copied!
See the AWS documentation for more information, including JAAS config for named profiles.
Configuration
kPow connects to a Kafka with the same configuration as a Kafka consumer or producer.
This configuration may be familiar to you, and is provided to kPow by environment variables.
The list of connection variables follows, many are optional. See the Kafka client docs for more.
