Configuring the Probe for Message Bus to integrate with Nokia Network Services Platform

The Message Bus Probe can be used to integrate with Nokia Network Services Platform (NSP) using the Kafka transport and the HTTPS REST transport. In the Kafka transport, there is an additional multi channel HTTPS REST transport component that can be enabled for Nokia NSP. The probe can be configured to integrate with Nokia NSP with the following configurations:

HTTPS REST and SSL Kafka
HTTPS REST and Plaintext Kafka

The following configuration files are supplied with the probe and are required by the integration with Nokia NSP:

message_bus_nokia_nfmp.props
message_bus_nokia_nfmp.rules
message_bus_nokia_nfmp_parser.json
nokiaNspKafkaTransport.properties
nokiaNspKafkaConnectionProperties.json
nokiaNspKafkaClient.properties
nokiaNspRestMulitChannelHttpTransport.json

To integrate with Nokia NSP, use the following steps:

Configure message_bus_nokia_nfmp.props for the Nokia NSP integration.

The Probe integration for Nokia NSP uses the Probe for Message Bus configured by the message_bus_nokia_nfmp.props file supplied with the probe. The following default probe properties are provided for the integration with Nokia NSP. Kafka transport is selected as the main transport type for this integration.

   #======================================================================
   # SETTING PROBE LOGS, PROPS, RULES

   #======================================================================
   # SETTING TRANSPORT TYPE

   TransportType    : 'KAFKA'
   TransportFile    : '$OMNIHOME/java/conf/nokiaNspKafkaTransport.properties'

   #======================================================================
   Username                       : 'nfmp_username'
   Password                       : 'nfmp_password'

   #======================================================================
   # SETTING SSL & KEYSTORE
   #======================================================================
   EnableSSL                     : 'true'
   KeyStore                      : '<Path to KeyStore>/keystore.jks'
   KeyStorePassword              : 'keystore_password'

   #======================================================================
   # SETTING RESYNC
   #======================================================================
   InitialResync                 : 'true'
   ResyncBatchSize               : 1000

Configure nokiaNspKafkaTransport.properties for the Nokia NSP integration:

   #==============================================================================
   # KAFKA CLIENT MODE AS CONSUMER
   #==============================================================================
   KafkaClientMode=CONSUMER

   #==============================================================================
   # LOCATION OF JSON FILE CONTAINING KAFKA & ZOOKEEPER CONNECTION PROPERTIES
   #==============================================================================
   ConnectionPropertiesFile=$OMNIHOME/java/conf/nokiaNspKafkaConnectionProperties.json

   #==============================================================================
   # LOCATION OF FILE CONTAINING REST CONNECTION PROPERTIES
   #==============================================================================
   httpConnectionPropertiesFile=$OMNIHOME/java/conf/nokiaNspRestMultiChannelHttpTransport.json

Note: If httpConnectionPropertiesFile is set to an empty string, it will not enable the support for HTTP REST communication which is required in Nokia NSP integration. You must ensure that this property is properly configured.

Configure nokiaNspKafkaConnectionProperties.json to enable either the Plaintext or SSL Kafka connection with the Nokia NSP.

To enable the Plaintext Kafka connection with the Nokia NSP, apply the following settings:

  {
   "zookeeper_client" : 
       {
           "target" : "",
           "properties" : "",
           "java_sys_props" : "",
           "topic_watch": false,
           "broker_watch": false
       },
   "brokers" : "PLAINTEXT://<Nokia SDN Host IP>:<Kafka Port>",
   "topics": "",
   "kafka_client" : 
     {
      "properties" : "<Absolute Path To $OMNIHOME/java/conf/nokiaNspKafkaClient.properties",
      "java_sys_props" : ""   
     }
}

Otherwise, to enable SSL Kafka connection with the Nokia NSP, apply the following settings:

{
   "zookeeper_client" :
   {
      "target" : "",
      "properties" : "",
      "java_sys_props" : "",
      "topic_watch": false,
      "broker_watch": false
   },
   "brokers" : "SSL://<Nokia SDN Host IP>:<Kafka port>",
   "topics": "",
   "kafka_client" :
   {
      "properties" : "<Absolute Path To $OMNIHOME/java/conf/nokiaNspKafkaClient.properties",
      "java_sys_props" : ""
   }
}

Configure the Kafka client settings in nokiaNspKafkaClient.properties by providing a location and password for the Keystore and Truststore. The following settings are required to enable the Plaintext Kafka connection:


security.protocol=PLAINTEXT
ack=all
group.id=NokiaNsp

enable.auto.commit=true
auto.commit.interval.ms=1000
session.timeout.ms=30000
key.deserializer=org.apache.kafka.common.serialization.StringDeserializer
value.deserializer=org.apache.kafka.common.serialization.StringDeserializer

Otherwise, to enable the SSL Kafka connection with the Nokia NSP, apply the following settings:


security.protocol=SSL
ssl.enabled.protocols=TLSv1.2,TLSv1.1,TLSv1
ssl.keystore.location=<Path To Keystore File>/samserver.keystore
ssl.keystore.password=<keystore password>
ssl.keystore.type=JKS
ssl.truststore.location=<Path To Keystore File>/samserver.keystore
ssl.truststore.password=<truststore password>
ssl.truststore.type=JKS

ack=all
group.id=NokiaNsp
enable.auto.commit=true
auto.commit.interval.ms=1000
session.timeout.ms=30000
key.deserializer=org.apache.kafka.common.serialization.StringDeserializer
value.deserializer=org.apache.kafka.common.serialization.StringDeserializer

Configure nokiaNspRestMulitChannelHttpTransport.json for settings on REST requests. Default settings has been provided.

Ensure following property has been added:
"keepTokens":"access_token, refresh_token, subscriptionId",
Check that the correct HOST and PORT of the target system is set for each request.
