Configuring your MiNiFi Java Agent

After you install the MiNiFi Java Agent, you need to update the configuration files.

If you want to configure your agent, use the conf/bootstrap.conf configuration file.

The MiNiFi Java Agent creates an auto-generated minifi.properties file at every startup. You should not use it for general agent configuration. If you want to override any property set in minifi.properties, you can do it by adding it to the end of the bootstrap.conf file.

For example, to change the content repository location, add the following to bootsrap.conf:
nifi.content.repository.directory.default=[***/path/to/repos/content***]

Follow these steps to configure the MiNiFi Java Agent:

  1. From the MiNiFi home directory, open the bootstrap.conf configuration file.
  2. Configure the agent class so that you can logically group MiNiFi Java instances according to their functionality. 
    c2.agent.class=[***AGENT_CLASS***]
  3. Configure the ID of the agent. If you do not specify an agent ID, MiNiFi generates a unique ID per agent instance. 
    c2.agent.identifier=[***AGENT_ID***]
  4. Set the c2.enable property to true to inform MiNiFi that run time flow instructions will be received from the Edge Flow Manager. 
    c2.enable=true
  5. Configure your Edge Flow Manager server endpoint. 
    c2.rest.path.base=[***REST API_BASE URL***]
c2.rest.path.heartbeat=[***HEARTBEAT_RELATIVE URL***]
c2.rest.path.acknowledge=[***ACKNOWLEDGE ENDPOINT_RELATIVE URL***]
    For example: 
    c2.rest.path.base=http://localhost:10090/efm/api
c2.rest.path.heartbeat=/c2-protocol/heartbeat
c2.rest.path.acknowledge=/c2-protocol/acknowledge
  6. Configure your heartbeat interval. 
    c2.agent.heartbeat.period=[***HEARTBEAT_INTERVAL***]
  7. Configure the config directory to be used by MiNiFi: 
    c2.config.directory=./conf
  8. Configure the C2 runtime properties. 
    c2.runtime.manifest.identifier=minifi
c2.runtime.type=minifi-java
  9. Configure the C2 request header type. 
    c2.rest.http.headers=Accept:application/json
  10. Configure the asset directories.

    The MiNiFi Java Agent uses separate properties to specify where legacy pushed assets and resources synchronized from Edge Flow Manager are stored on the agent file system:

    c2.asset.directory

    It specifies the root directory for assets received through the asset push command. This property applies to the legacy asset push feature only.

    c2.asset.repository.directory

    It specifies the root directory for resources managed through the Edge Flow Manager Resource Manager. The agent stores synchronized resources under this directory and resolves asset references in flow parameters to local paths relative to this location. This property was introduced in CEM-AGENTS-JAVA 4.12.0.0.

  11. Restart the agent.
