Enable partition level metric collection

You must enable SMM to configure partition level metrics about Kafka topics.

You have obtained the Cloudera Manager Kafka service name. See Obtain the Kafka service name for information.

In Cloudera Manager, select Hosts, and then Hosts Configuration.
To allow SMM to collect partition level metrics about Kafka topics, add the following to Cloudera Manager Agent Monitoring Advanced Configuration Snippet (Safety Valve):
```
<serviceName>_broker_topic_partition_metrics_for_smm_enabled=true
```
When you are configuring partition level metrics collection, your Kafka service name should always be in lower case letters.

For example if KAFKA is the Kafka serviceName, enter the following:
```
kafka_broker_topic_partition_metrics_for_smm_enabled=true
```
Restart Cloudera Manager if prompted to do so.
