Broker Topic Metrics

Menu

The Broker Topic Metrics metric group contains per-broker metrics regarding topics. The metrics available are:

  • Broker Topic Bytes In
  • Broker Topic Bytes Out
  • Broker Topic Messages In

Broker Topic Bytes In

The Broker Topic Bytes In metric shows the mean rate and one minute rate of incoming bytes to the cluster. This metric may be useful for diagnosing network bottleneck issues, which can help you decide to enable end-to-end message compression. See here for more information on cluster compression settings. If you are hitting the limit of how much your cluster can process, you can also consider increasing the capacity of your cluster. This can be achieved by either adding new nodes to the cluster or upgrading the individual nodes in the cluster. See here for more information on expanding your cluster.

Broker Topic Bytes Out

The Broker Topic Bytes Out metric shows the mean rate and one minute rate of outgoing bytes to the cluster. This metric may be useful for diagnosing network bottleneck issues, which can help you decide to enable end-to-end message compression. See here for more information on cluster compression settings. If you are hitting a limit of how much your cluster can process, you can also consider increasing the capacity of your cluster. This can be achieved by either adding new nodes to the cluster or upgrading the individual nodes in the cluster. See here for more information on expanding your cluster.

Broker Topic Messages In

The Broker Topic Messages In metric shows the mean rate and one minute rate of incoming topic messages per second to the cluster. This metric may be useful to see how much load the cluster is under, and when you might need to expand the cluster. If you are hitting a limit of how much your cluster can process, you can also consider increasing the capacity of your cluster. This can be done by either adding new nodes to the cluster or upgrading the individual nodes in the cluster. See here for more information on expanding your cluster.
