srm-service

Learn how to use the srm-service command line tool which is used to launch the SRM REST service and Kafka streams application.

The srm-service tool launches a REST service and a Kafka streams application, which enable users to monitor replications.

Each instance of the service is associated with a specific target cluster. The tool uses a properties file to acquire connection information for the target cluster. When not specified otherwise, it uses the default configuration file. If required, you can use the --config option to specify a different properties file.

Additionally, a second configuration file, srm-service.yaml, is required for settings specific to the service, for example which HTTP ports to use. Use the --yaml option to specify which srm-service.yaml file to use. As with --config, the --yaml option is only required if you are storing the file in a non-default location. For .rpm or .deb based installations, the yaml file is read from /opt/streams-replication-manager/config/srm-service.yaml. For ZIP or TAR based installations, the service will default to $SRM_CONF_DIR/srm-service.yaml.

Run the SRM services with following command:

srm-service --target [TARGET_CLUSTER]

The yaml file supports Dropwizard properties as well as changing the rpc port used by srm-service nodes for communication. The default port is 6669. To change the default port, add the following to the yaml configuration file:

rpcPort: 8081
server:
  applicationConnectors:
    - type: http
      port: 8081
