参考：Docs » Configuration
初次配置 Rally，需要运行命令
esrally configure --advanced-config
压测结果的存储类型分 2 类：
- in-memory 临时存储，打印到标准输出后就没了
- elasticsearch 存储在一个指定的 ES 集群中，方便对比
跑上面的命令时，在选择存储类型时开始不一样：
in-memory
Enter the benchmark root directory (default: /home/apps/.rally/benchmarks):
Using default value '/home/apps/.rally/benchmarks'
Enter your Elasticsearch project directory: (default: /home/apps/.rally/benchmarks/src/elasticsearch):
Using default value '/home/apps/.rally/benchmarks/src/elasticsearch'
Where should metrics be kept?
(1) In memory (simpler but less options for analysis)
(2) Elasticsearch (requires a separate ES instance, keeps all raw samples for analysis)
(default: 1): 1
Do you want Rally to keep the Elasticsearch benchmark candidate installation including the index (will use several GB per trial run)? (default: False):
Configuration successfully written to /home/apps/.rally/rally.ini. Happy benchmarking!
elasticsearch
Enter the benchmark root directory (default: /home/apps/.rally/benchmarks):
Using default value '/home/apps/.rally/benchmarks'
Enter your Elasticsearch project directory: (default: /home/apps/.rally/benchmarks/src/elasticsearch):
Using default value '/home/apps/.rally/benchmarks/src/elasticsearch'
Where should metrics be kept?
(1) In memory (simpler but less options for analysis)
(2) Elasticsearch (requires a separate ES instance, keeps all raw samples for analysis)
(default: 1): 2
Enter the host name of the ES metrics store (default: localhost):
Using default value 'localhost'
Enter the port of the ES metrics store: 9200
Use secure connection (True, False) (default: False):
Username for basic authentication (empty if not needed) (default: ):
Password for basic authentication (empty if not needed) (default: ):
Enter a descriptive name for this benchmark environment (ASCII, no spaces) (default: local): rally_demo
Do you want Rally to keep the Elasticsearch benchmark candidate installation including the index (will use several GB per trial run)? (default: False):
Configuration successfully written to /home/apps/.rally/rally.ini. Happy benchmarking!
配置项说明
-
Benchmark root directory：Rally 存放测试数据的根目录，默认为
~/.rally/benchmarks。可能需要几十 GB，因为某些场景的测试数据解压后很大。 -
Elasticsearch project directory：存放 ES 源代码的目录。Rally 默认建立一个本地的 ES 实例，对其进行性能测试。用 Gradle Wrapper 来编译源代码：
./gradlew clean
./gradlew :distribution:tar:assemble
- Metrics store type：压测结果数据的存储类型
in-memory：默认，压测报告的数据比较少
elasticsearch：用户指定单独的 ES 集群来存储报告，压测结果非常详细
- Metrics store settings：ES 实例连接信息配置，压测结果存储类型为 elasticsearch 时生效。单实例已经足够用了。另外，ssl 配置其实也用不上的，如果使用了的话，需要配置一下：
datastore.ssl.verification_mode 开关 ssl 认证，默认为 none
datastore.ssl.certificate_authorities 指定 ca 证书存放路径
- Name for this benchmark environment：压测结果存储类型为 elasticsearc 时当做索引名称使用，便于区分不同压测的报告数据。
端口说明
esrally 建立 ES 集群时，使用这些端口：
39200-39300 (HTTP)
39300-39400 (transport)
所以使用本地 ES 实例来存储压测结果时，ES 实例要避开这些端口
脚本说明
~/.rally/rally.ini 这个无法自定义目录，每次执行 esrally configure --advanced-config 命令，都会覆盖它。这个设定太不友好，所以第一次跑 config 命令后，后续的修改推荐使用 vim 方式。

| [node] | root.dir 为压测数据存放根目录 |
| [source] | ES 源代码的下载配置，从 github 下载 |
| [benchmarks] | 样本数据存放目录配置 |
| [reporting] | 压测结果存储配置，in-memory or elasticsearch |
| [tracks] | tracks 配置文件下载地址，从 github 下载，一个业务类型称为一个 track |
| [teams] | es 配置文件下载地址，从 github 下载，这里提供多种 es 配置，一种配置统称称为一个 car |
对比发现，只有 reporting 这一项不同。
reporting 为 elasticsearch 时，如果没有安全认证，那么 datastore.secure 必须为 False，不能留空，不然报错：
[ERROR] Cannot race. Error in race control (Cannot convert [] to bool.)
