Configuring your MiNiFi C++ Agent

After you have installed the MiNiFi C++ Agent, you need to update the configuration files for proper operation.

MiNiFi C++ relies on two configuration files: minifi.properties for general settings and config.yml for flow configuration.

Follow these steps to configure the MiNiFi C++ Agent:

From the MiNiFi home directory, locate and open the minifi.properties configuration file.
Configure the agent class to logically group MiNiFi C++ instances based on their functionality using the following setting:
```
nifi.c2.agent.class=[***AGENT_CLASS***]
```
Replace [***AGENT_CLASS***] with your agent class name. For example: nifi.c2.agent.class=my_agent_class

note
Leading and trailing whitespaces are accepted for Agent Class names so consider this when configuring agents.
Configure the ID of the agent. If you do not specify an agent ID, MiNiFi generates a unique ID per agent instance.
```
nifi.c2.agent.identifier=[***AGENT_ID***]
```
Replace [***AGENT_ID***] with your chosen ID. For example: nifi.c2.agent.identifier=minifi_cpp_13
Enable MiNiFi to receive runtime flow instructions from the by setting the nifi.c2.enable property to true.
```
nifi.c2.enable=true
```

Configure your server endpoint.

nifi.c2.rest.url=http://[***EFM SERVER_IP ADDRESS***]:10090/efm/api/c2-protocol/heartbeat
nifi.c2.rest.url.ack=http://[***EFM SERVER_IP ADDRESS***]:10090/efm/api/c2-protocol/acknowledge

Replace [***EFM SERVER_IP ADDRESS***] with the IP address of the server endpoint. For example with efm-host.corp.local

Configure the heartbeat interval.
```
nifi.c2.agent.heartbeat.period=[***HEARTBEAT_INTERVAL***]
```
Replace [***HEARTBEAT_INTERVAL***] with the time period you want to set as the frequency for the the agent to send a heartbeat to the . The format can be an integer in milliseconds, or an integer followed by a time period unit.

For example: nifi.c2.agent.heartbeat.period=5000

5 sec is also a valid value.

Optional: Configure the metrics for your MiNiFi C++ Agent.

For more information, see Metrics in the Apache NiFi - MiNiFi - C++ C2 Readme.

nifi.c2.root.class.definitions=metrics
nifi.c2.root.class.definitions.metrics.name=metrics
nifi.c2.root.class.definitions.metrics.metrics=runtimemetrics,loadmetrics,processorMetrics
nifi.c2.root.class.definitions.metrics.metrics.runtimemetrics.name=RuntimeMetrics
nifi.c2.root.class.definitions.metrics.metrics.runtimemetrics.classes=DeviceInfoNode,FlowInformation
nifi.c2.root.class.definitions.metrics.metrics.loadmetrics.name=LoadMetrics
nifi.c2.root.class.definitions.metrics.metrics.loadmetrics.classes=QueueMetrics,RepositoryMetrics
nifi.c2.root.class.definitions.metrics.metrics.processorMetrics.name=ProcessorMetric
nifi.c2.root.class.definitions.metrics.metrics.processorMetrics.classes=GetFileMetrics

Restart the agent to apply the changes.
