Locust性能测试6-命令行参数详解
前言
当我们在linux上使用locust工具压测的时候，会使用no-web模式，然后需要收集运行的日志，方便查找问题。
命令行参数
输入locust --help 查看所有的命令行参数
> locust --help
Usage: locust [options] [LocustClass [LocustClass2 ... ]]
Options:
-h, --help show this help message and exit
-H HOST, --host=HOST Host to load test in the following format:
http://10.21.32.33
--web-host=WEB_HOST Host to bind the web interface to. Defaults to '' (all
interfaces)
-P PORT, --port=PORT, --web-port=PORT
Port on which to run web host
-f LOCUSTFILE, --locustfile=LOCUSTFILE
Python module file to import, e.g. '../other.py'.
Default: locustfile
--csv=CSVFILEBASE, --csv-base-name=CSVFILEBASE
Store current request stats to files in CSV format.
--master Set locust to run in distributed mode with this
process as master
--slave Set locust to run in distributed mode with this
process as slave
--master-host=MASTER_HOST
Host or IP address of locust master for distributed
load testing. Only used when running with --slave.
Defaults to 127.0.0.1.
--master-port=MASTER_PORT
The port to connect to that is used by the locust
master for distributed load testing. Only used when
running with --slave. Defaults to 5557. Note that
slaves will also connect to the master node on this
port + 1.
--master-bind-host=MASTER_BIND_HOST
Interfaces (hostname, ip) that locust master should
bind to. Only used when running with --master.
Defaults to * (all available interfaces).
--master-bind-port=MASTER_BIND_PORT
Port that locust master should bind to. Only used when
running with --master. Defaults to 5557. Note that
Locust will also use this port + 1, so by default the
master node will bind to 5557 and 5558.
--heartbeat-liveness=HEARTBEAT_LIVENESS
set number of seconds before failed heartbeat from
slave
--heartbeat-interval=HEARTBEAT_INTERVAL
set number of seconds delay between slave heartbeats
to master
--expect-slaves=EXPECT_SLAVES
How many slaves master should expect to connect before
starting the test (only when --no-web used).
--no-web Disable the web interface, and instead start running
the test immediately. Requires -c and -r to be
specified.
-c NUM_CLIENTS, --clients=NUM_CLIENTS
Number of concurrent Locust users. Only used together
with --no-web
-r HATCH_RATE, --hatch-rate=HATCH_RATE
The rate per second in which clients are spawned. Only
used together with --no-web
-t RUN_TIME, --run-time=RUN_TIME
Stop after the specified amount of time, e.g. (300s,
20m, 3h, 1h30m, etc.). Only used together with --no-
web
-L LOGLEVEL, --loglevel=LOGLEVEL
Choose between DEBUG/INFO/WARNING/ERROR/CRITICAL.
Default is INFO.
--logfile=LOGFILE Path to log file. If not set, log will go to
stdout/stderr
--print-stats Print stats in the console
--only-summary Only print the summary stats
--no-reset-stats [DEPRECATED] Do not reset statistics once hatching has
been completed. This is now the default behavior. See
--reset-stats to disable
--reset-stats Reset statistics once hatching has been completed.
Should be set on both master and slaves when running
in distributed mode
-l, --list Show list of possible locust classes and exit
--show-task-ratio print table of the locust classes' task execution
ratio
--show-task-ratio-json
print json data of the locust classes' task execution
ratio
-V, --version show program's version number and exit

| -f LOCUSTFILE, –locustfile=LOCUSTFILE | LOCUSTFILE | 指定运行 Locust 性能测试文件，默认为: locustfile.py |
| –csv=CSVFILEBASE, –csv-base-name=CSVFILEBASE | CSVFILEBASE | 以CSV格式存储当前请求测试数据。 |
| –master | 不带参数 | Locust 分布式模式使用，当前节点为 master 节点。 |
| –slave | 不带参数 | Locust 分布式模式使用，当前节点为 slave 节点。 |
| –master-host=MASTER_HOST | MASTER_HOST | 分布式模式运行，设置 master 节点的主机或 IP 地址，只在与 –slave 节点一起运行时使用，默认为：127.0.0.1. |
