Produce test messages to a Hermes topic by configuring a producer client.

## Vorbereitungen

* Secure your Kafka topics by generating a ServiceNow® instance-signed certificate and keystore. You must provide truststore and keystore details when you configure the Hermes producer. See [Set up a secure connection to the Hermes Messaging Service](https://servicenow-prod.fluidtopics.net/E9eFecp0xYW~Av3YxMUT9w "Secure your Kafka topics by generating a ServiceNow instance-signed certificate.").
* Download and install Apache Kafka. See [Prepare your Apache Kafka client environment](https://servicenow-prod.fluidtopics.net/ZYiWlqUuWuaSEoXKY4w3kg "Install the Apache Kafka binaries on your Unix or Windows client machine.").
* Create a test topic to store the test messages that you produce. For details, see [Create a test topic in Hermes using the Kafka client](https://servicenow-prod.fluidtopics.net/yRi94EGo~4Y5VlscX_qriQ "Create a topic for sending and receiving test messages in the Hermes Kafka cluster.").

## Warum und wann dieser Vorgang ausgeführt wird

The following steps describe how to configure a producer client and send test messages to the Hermes Kafka cluster. Refer to these steps when you're ready to produce messages to Hermes for business or production purposes.

## Prozedur

1. Navigate to the config directory where you extracted Kafka.
   * For example, on Unix:

         cd /home/user/Software/kafka/config

   * For example, on Windows:

         cd C:\Software\kafka\config

   {#produce-messages-hermes__choices_fgv_zqt_w1c}
2. Configure a producer.
   1. Open the producer.properties file.
   2. Configure the following SSL properties:  

          security.protocol=SSL

          ssl.truststore.password=<truststore password>

          ssl.truststore.location=<path to truststore.p12>

          ssl.truststore.type=PKCS12

          ssl.keystore.password=<keystore password>

          ssl.keystore.location=<path to keystore.p12>

          ssl.keystore.type=PKCS12

          ssl.key.password=<keystore password>

      Replace the following placeholder variables:
      * `<truststore password>` with your truststore password
      * `<path to truststore.p12>` with the path to your truststore file
      * `<keystore password>` with your keystore password
      * `<path to keystore.p12>` with the path to your keystore file
      {#produce-messages-hermes__ul_tvh_twp_twb}
   3. Save your changes in plain text.
   {#produce-messages-hermes__substeps_jt5_lwp_twb}
3. Produce a test topic.
   1. Navigate to the Kafka directory.
   2. Run the following command:  
      Unix:

          ./bin/kafka-console-producer.sh --topic snc.<instance_name>.<namespace>.sn_<app_id>.<topic_name> --producer.config ./config/producer.properties --bootstrap-server <instance_name>.service-now.com:4000,<instance_name>.service-now.com:4001,<instance_name>.service-now.com:4002,<instance_name>.service-now.com:4003

      Windows:

          bin\windows\kafka-console-producer.bat --topic snc.<instance_name>.<namespace>.sn_<app_id>.<topic_name> --producer.config config\producer.properties --bootstrap-server <instance_name>.service-now.com:4000,<instance_name>.service-now.com:4001,<instance_name>.service-now.com:4002,<instance_name>.service-now.com:4003

      Replace the following placeholder variables:
      * `<instance_name>` with your instance name
      * `<namespace>` with the namespace of the domain your Kafka topic belongs to (optional)
      * `<app_id>` with the application ID
      * `<topic_name>` with a unique test topic name
      {#produce-messages-hermes__ul_tjk_zxp_twb}  
      Hinweis:  
      Each part of the topic name is case-sensitive.
   3. Send test messages to the test topic.  
      For example:

          test1
          test2
          test3

   {#produce-messages-hermes__substeps_mlm_vxp_twb}

## Ergebnisse

Test messages are produced to the test topic in the Hermes Kafka cluster.
