我正在尝试为分布式 locust 运行创建配置,我有一个包含已定义任务的 .py 脚本,并且我有简单的 taurus 配置只是为了使其工作:
execution:
executor: locust
master: true
slaves: 1
scenario: tns
concurrency: 10
ramp-up: 10s
iterations: 100
hold-for: 10s
scenarios:
tns:
script: /usr/src/app/scenarios/locust_scenarios/sample.py
reporting:
- module: final-stats
dump-csv: test_result.csv
- module: console
- module: passfail
criteria:
- avg-rt>250ms for 30s, continue as failed
- failures>5% for 5s, continue as failed
- failures>50% for 10s, stop as failed
然后我启动蝗虫从节点:
python -m locust.main -f scenarios/locust_scenarios/sample.py --slave --master-host=localhost
并执行测试,这是日志

蝗虫日志显示蝗虫奴隶已连接并准备集群。
我应该怎么做才能让它运行?谢谢
