Docs Self-Managed Reference Monitoring Metrics Public Metrics Reference This version is no longer supported. It reached its end of life on December 22, 2024. Please upgrade to a supported version. Public Metrics Reference This section provides reference descriptions about the public metrics exported from Redpanda’s /public_metrics endpoint. Use /public_metrics for your primary dashboards for system health. Use /metrics for detailed analysis and debugging. In a live system, Redpanda metrics are exported only for features that are in use. For example, a metric for consumer groups is not exported when no groups are registered. To see the available public metrics in your system, query the /public_metrics endpoint: curl http://<node-addr>:9644/public_metrics | grep "[HELP|TYPE]" Cluster metrics redpanda_cluster_brokers Number of configured, fully commissioned brokers in a cluster. Type: gauge How to monitor: create an alert for when this gauge dips below a steady-state threshold, as a node(s) has become unresponsive. redpanda_cluster_controller_log_limit_requests_available_rps Limit on the available requests per second (RPS) for a cluster controller log. Type: gauge Labels: redpanda_cmd_group=("move_operations" | "topic_operations" | "configuration_operations" | "node_management_operations" | "acls_and_users_operations") redpanda_cluster_controller_log_limit_requests_dropped Number of requests dropped by a cluster controller log due to exceeding redpanda_cluster_controller_log_limit_requests_available_rps. Type: counter Labels: redpanda_cmd_group=("move_operations" | "topic_operations" | "configuration_operations" | "node_management_operations" | "acls_and_users_operations") Usage: when this counter increases, it indicates that the controller is dropping requests. redpanda_cluster_partition_moving_from_node Number of partition replicas in the cluster that are currently being removed from a node. Type: gauge Usage: when this gauge is non-zero, determine whether there is an expected or unexpected reassignment of partitions that is causing movement of partition replicas. redpanda_cluster_partition_moving_to_node Number of partition replicas in the cluster that are currently being added or moved to a node. Type: gauge Usage: when this gauge is non-zero, determine whether there is an expected or unexpected reassignment of partitions that is causing movement of partition replicas. redpanda_cluster_partition_node_cancelling_movements During a partition movement cancellation operation, the number of partition replicas that were being moved that now need to be cancelled. Type: gauge How to monitor: when this gauge is non-zero, determine whether there is an expected or unexpected reassignment of partitions that is causing movement of partition replicas. redpanda_cluster_partitions Number of partitions managed by a cluster. Includes partitions of the controller topic, but not replicas. Type: gauge redpanda_cluster_topics Number of topics in a cluster. Type: gauge redpanda_cluster_unavailable_partitions Number of unavailable partitions (the partitions that lack quorum among their replica group) in the cluster. Type: gauge Usage: when this gauge is non-zero, it indicates that a partition(s) doesn’t have quorum and thus doesn’t have an active leader. To mitigate, consider increasing the number of brokers and the partition replication factor. Infrastructure metrics redpanda_cpu_busy_seconds_total Total CPU busy time in seconds.

This lists all resources that have at least one CA configured. Type: gauge Labels: area detail Usage: This metric is recorded for all resources that may have a TLS certificate installed. The area and detail labels provide a hierarchical way of identifying a single resource you need information on. redpanda_tls_certificate_expires_at_timestamp_seconds The expiration time, represented as a Unix-style timestamp, for the shortest-lived installed certificate. While more than one certificate may be installed for a resource, this provides only the timestamp of the next certificate to expire. This lists all resources that have at least one certificate installed. Type: gauge Labels: area detail Usage: This metric is recorded for all resources that may have a TLS certificate installed. The area and detail labels provide a hierarchical way of identifying a single resource you need information on. redpanda_tls_certificate_serial The serial number of the shortest-lived installed certificate. These serial numbers are technically unbounded. As such, this will return the least significant 4B digits of the integer representation certificate’s serial number. While more than one certificate may be installed for a resource, this provides only the serial number of the next certificate to expire. This lists all resources that have at least one certificate installed. Type: gauge Labels: area detail Usage: This metric is recorded for all resources that may have a TLS certificate installed.

This lists all resources that have at least one certificate installed. Type: gauge Labels: area detail Usage: This metric is recorded for all resources that may have a TLS certificate installed. The area and detail labels provide a hierarchical way of identifying a single resource you need information on. redpanda_tls_certificate_valid Indicates whether a given resource has at least one valid installed TLS certificate. Querying this will provide a check on all resources with at least one certificate installed. The value of this gauge is either 1 to indicate presence of a valid certificate or 0 to indicate the absence of a valid certificate. Type: gauge Labels: area detail Usage: This metric is recorded for all resources that may have a TLS certificate installed.
