Transaction Coordinator metrics

[themkarimi]

Hi,

I have been trying to enable kafka transactions coordinator metrics using these config but the metrics are not exposed by the brokers:
` - pattern: "kafka.server<type=transaction-coordinator-metrics, name=(.+)><>(.+):"
name: kafka_server_transaction_coordinator_$1
type: GAUGE

- pattern: kafka.server<type=transaction-coordinator-metrics, name=(.+)><>Value
  name: kafka_server_transaction_coordinator_$1
  type: GAUGE

- pattern: "kafka.coordinator.transaction<type=TransactionCoordinator, name=(.+)><>Count"
  name: kafka_transactioncoordinator_$1_total
  type: COUNTER

# AddPartitionsToTxnManager metrics (transactional verification)
- pattern: kafka.server<type=AddPartitionsToTxnManager, name=(VerificationFailureRate)><>Value
  name: kafka_server_addpartitionstotxnmanager_verification_failure_rate
  type: GAUGE

- pattern: kafka.server<type=AddPartitionsToTxnManager, name=(VerificationTimeMs)><>(\d+)thPercentile
  name: kafka_server_addpartitionstotxnmanager_verification_time_ms
  type: GAUGE
  labels:
    quantile: "0.$2"

- pattern: kafka.server<type=AddPartitionsToTxnManager, name=(VerificationTimeMs)><>(Count|Mean|Min|Max)
  name: kafka_server_addpartitionstotxnmanager_verification_time_ms_$2
  type: GAUGE
`

can anyone helm me with this?
