How can I track how many ACLs have been created on a Confluent Cloud cluster

Description

Each Confluent Cluster type has a limit on the number of ACLs that can be created.  These limits can be found in the Confluent Cloud documentation's cluster limit comparison table.

There is currently no way to use the Confluent Cloud console or Service Quotas API to determine the number of ACLs that have been created on a Confluent Cloud cluster.  The following suggestions can be used as a workaround until ACL usage can be tracked via the Service Quotas API and/or the Confluent Cloud Console.

Applies To

All Confluent Cloud clusters.

Resolution

The Confluent Cloud Rest API

• jq can be used to count the number of ACLs returned in the data array:

  • jq -r '.data | length'

The Confluent Cloud CLI

• confluent kafka acl list --all | wc -l

The Apache Kafka CLI for ACL management

• kafka-acls --bootstrap-server <ccloud_bootstrap_endpoint>:9092 --command-config
      <path/to/config.properties> --list | grep "principal=" | wc -l
