Load testing tools

Use the Pulsar performance tools to generate publish and consume workloads with controlled message rates and sizes. For repeatable scenarios, comparisons between revisions, metrics, and profiling, see the performance testing framework.

The old pulsar-perf simulation-client and simulation-controller commands and their LoadSimulationClient / LoadSimulationController implementations were removed. Update scripts that invoke these commands to use the current performance tools; their controller commands are no longer available.

Broker Monitor

To observe load-manager data, use the broker monitor, which is implemented in org.apache.pulsar.testclient.BrokerMonitor. The broker monitor will print tabular load data to the console as it is updated using watchers.

Usage

To start a broker monitor, use the monitor-brokers command in the pulsar-perf script:

pulsar-perf monitor-brokers --connect-string <zookeeper host:port>

The console will then continuously print load data until it is interrupted.
