Configuring your MiNiFi C++ agent

After you install the MiNiFi C++ agent, you need to update the configuration files.

MiNiFi C++ is configured through two files: minifi.properties is used for general configuration and config.yml is used for configuring your flow.

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

From the MiNiFi home directory, open the minifi.properties configuration file.
Configure the agent class so that you can logically group MiNiFi C++ instances according to their functionality.
```
nifi.c2.agent.class=[***AGENT_CLASS***]
```
Replace [***AGENT_CLASS***] with the name of your agent class, 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 the ID of your choice, for example: nifi.c2.agent.identifier=minifi_cpp_13
Set the nifi.c2.enable property to true to inform MiNiFi that run time flow instructions will be received from EFM.
```
nifi.c2.enable=true
```

Configure your EFM 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 EFM server endpoint, for example with efm-host.corp.local

Configure your 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 EFM.

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.
