Manually configuring GCP topic, sink, and subscription - Adaptive Applications - BlueCat Gateway - 21.3.1

Cloud Discovery & Visibility creates a hash which is appended to the names of GCP topic, sink, and subscription strings. The hash is produced from a string that is a combination of the GCP Project ID, Address Manager URL, the Address Manager username, and the configuration name. In the following example, the string consists of the following information:

• Project ID—eng-dev-cloud-integration-01
• Address Manager URL—192.168.113.59
• Address Manager username —anh
• Configuration name—test10

You can manually generate the hash of the string using the following command:

echo -n <string> | md5sum

If this fails due to the account having insufficient write permissions to those services, contact a GCP administrator to grant you temporary write access or have them configure the GCP topic, sink, and subscription as follows:

• Create a topic with the name BC-CDV-PUBSUB-TOPIC-<hash string>. For example, the topic created is BC-CDV-PUBSUB-TOPIC-b30f604746001d56a0890d4488e48159.
  
  
  
  
• Create a sink with a name in the following format: BC-CDV-LOGGING-SINK-<hash string>. For example, the sink created is BC-CDV-LOGGING-SINK-b30f604746001d56a0890d4488e48159.
  
  
  
  
• Select the Cloud Pub/Sub topic sink service and choose the pub/sub topic created earlier. For example, BC-CDV-PUBSUB-TOPIC-b30f604746001d56a0890d4488e48159.
  
  
  
  
• Select the logs to include in the sink by creating an inclusion filter to determine which logs are included in the logs routing sink. For example:

  (
  protoPayload.methodName =~ ("(?i)networks" OR "(?i)subnetworks" OR "(?i)instances" OR
  "(?i)backendServices" OR "(?i)targetPools" OR "(?i)urlMaps" OR
  "(?i)forwardingRules" OR "(?i)targetHttpProxies" OR
  "(?i)targetHttpsProxies" OR "(?i)targetSslProxies" OR "(?i)targetTcpProxies" OR
  "(?i)managedZones")
  AND severity="NOTICE" AND cloudaudit.googleapis.com%2Factivity AND protoPayload.response.status = "running"
  )
  OR
  (
  protoPayload.methodName="compute.instances.guestTerminate" AND severity="INFO"
  )
  OR
  (
  protoPayload.methodName =~ ("dns.managedZones.(?i)" OR "dns.changes.(?i)")
  AND severity="NOTICE" AND cloudaudit.googleapis.com%2Factivity
  )

  
  
  
  
  
• Optionally, select the logs to filter out of the sink.
• Create a Pub/Sub Subscription with a name in the following format: BC-CDV-PUBSUB-SUBSCRIPTION-<hash string>. For example, the subscription created is BC-CDV-PUBSUB-SUBSCRIPTIONb30f604746001d56a0890d4488e48159.
• Select the Cloud Pub/Sub topic and choose the pub/sub topic created earlier. For example, BC-CDV-PUBSUB-TOPIC-b30f604746001d56a0890d4488e48159.
