moleculer/perf-tester repository overview
Performance Tester
It's a tool to test your Moleculer based project tech stack including transporter, serializer, discoverer.
Under the hood
The test creates 2 ServiceBroker instances (producer and consumer) with a simple echo service which responses the received params. The producer calls the echo service and waits for the response one-by-one continuously (measuring the latency).
You can start the consumer and producer brokers separately (
MODEenv var) in order to test transporter cluster, or generate more request with multiple consumers and/or producers.
Usage
Run the tester with NATS transporter
docker run -e TRANSPORTER=nats://demo.nats.io:4222 moleculer/perf-tester
Test transporter cluster
If you would like to test transporter cluster nodes separately, you can start the test brokers individually with the MODE env var.
Start the consumer
docker run -e TRANSPORTER=nats://nats-1:4222 -e MODE=consumer moleculer/perf-tester
Start the producer
docker run -e TRANSPORTER=nats://nats-2:4222 -e MODE=producer moleculer/perf-tester
Throughput measurement
The test (by default) measures the latency of action calls. It means, the producer makes an action call and wait the response. If the response is received, it will send the next request.
If you would like to measure the throughput of the system, set the FLOOD env var (greater than zero) to control the number of parallel pending action calls (max-in-flight).
Available environment variables
| Variable | Example value | Description |
|---|---|---|
TRANSPORTER | NATS or redis://redis:6379 | Transporter connection string or name. Supports all built-in transporters. |
SERIALIZER | JSON | Serializer name. Supports all built-in serializers. |
DISCOVERER | Local | Discoverer name. Supports all built-in discovers. |
DURATION | 5 | Test duration in seconds. If null, the test is running infinity. |
MODE | consumer, producer, null | Test mode. |
NODE_ID | consumer-123 | Custom nodeID. Use only in consumer or producer mode if you want custom nodeID for brokers. Otherwise ServiceBroker generates from hostname and PID. |
FLOOD | 0, 1000 | Number of simultaneously requests. 0 - measures the latency, if greater than 0, measures the throughput |
