elasticsearch esrally 性能测试实操
============================
最新在用 esrally 测试 es 的性能，今天把相关操作记录下。本人非专业测试，各位大佬请轻喷。
关于 esrally 的文档，请移步：esrally测试
esrally 是个 elastic 官方的测试工具，可以对 es 进行压力测试。其运行对环境有一定要求，如 python版本，JDK要求等，这里为了不去配环境，采用 docker 跑 esrally，所以首先你需要拉取 esrally 的官方镜像：
docker pull elastic/esrally
准备数据
接下来就是准备测试数据。
这里为了方便，也是采用常用的测试数据，请下载这里的数据：documents-2.json
下载后是个 bz2 的压缩文件，请先解压。
因为这块的测试数据时 geonames，实际字段不多，就是简单的地理位置信息和人口信息等。
主要最后解压解包出来应该是：documents-2.json。
接下来定义 index.json，这里主要是对测试数据的字段定义：
index.json
{
"settings": {
"index.number_of_replicas": 0
},
"mappings": {
"docs": {
"dynamic": "strict",
"properties": {
"geonameid": {
"type": "long"
},
"name": {
"type": "text"
},
"latitude": {
"type": "double"
},
"longitude": {
"type": "double"
},
"country_code": {
"type": "text"
},
"population": {
"type": "long"
}
}
}
}
}
按照 esrally 的测试要求，定义 track 信息：
track.json
{
"version": 2,
"description": "Tutorial benchmark for Rally",
"indices": [
{
"name": "geonames",
"body": "index.json",
"types": [ "docs" ]
}
],
"corpora": [
{
"name": "rally-tutorial",
"documents": [
{
"source-file": "documents-2.json", # 测试文件名
"document-count": 11396503, # 测试数据大小，wc -l documents-2.json
"uncompressed-bytes": 3547613828 # 测试数据的字节数
}
]
}
],
"schedule": [ # 以下定义了不同的测试，如对索引的创建与删除，bulk插入，query-match，GC情况等
{
"operation": {
"operation-type": "delete-index"
}
},
{
"operation": {
"operation-type": "create-index"
}
},
{
"operation": {
"operation-type": "cluster-health",
"request-params": {
"wait_for_status": "green"
},
"retry-until-success": true
}
},
{
"operation": {
"operation-type": "bulk",
"bulk-size": 5000
},
"warmup-time-period": 120,
"clients": 8
},
{
"operation": {
"operation-type": "force-merge"
}
},
{
"operation": {
"name": "query-match-all",
"operation-type": "search",
"body": {
"query": {
"match_all": {}
}
}
},
"clients": 8,
"warmup-iterations": 1000,
"iterations": 1000,
"target-throughput": 100
}
]
}
以上都是数据准备，接下来就可以通过 docker run 直接跑 esrally 测试了。

正式测试
准备好后，测试下：
docker run --rm -v /home/test/rally/:/rally/.rally/ elastic/rally list tracks --track-path=/rally/.rally/benchmarks/data/single
然后是正式跑测试数据：
我的环境是 es集群在一个环境，测试放另一个环境。
docker run 命令有点长，放在 shell 脚本中：
#!/bin/bash
docker run --privileged=true --rm -v /root/myrally:/rally/.rally elastic/rally race --pipeline=benchmark-only --target-hosts=172.22.xxx.xxx:9200 --track-path=/rally/.rally/benchmarks/tracks/tracktest --client-options="basic_auth_user:'xxx',basic_auth_password:'xxx'" --offline --report-format=csv --report-file=/rally/.rally/benchmarks/result.csv
主要主要这几个配置：
--pipeline=benchmark-only 仅性能测试
--target-hosts=172.22.xxx.xxx:9200 测试的es集群
--track-path=/rally/.rally/benchmarks/tracks/tracktest 定义的测试项
--client-options="basic_auth_user:'xxx',basic_auth_password:'xxx'" 如果你定义了es的xpack认证的话
--offline 离线
--report-format=csv 输出格式
--report-file=/rally/.rally/benchmarks/result.csv 输出到具体文件
然后直接 运行脚本 就可以看到：
# sh docker_run.sh

后面可以对 csv 文件处理下：
import pandas as pd
def csv2excel_cluster():
csv = pd.read_csv("result.csv", encoding='utf-8')
csv.to_excel("result.xlsx", sheet_name="cluster")
