hey工具魔改

hey是 Google一女工程师（现在在aws）使用 Go 语言开发的类似 apache ab 的性能测试工具。相比 ab，boom跨平台性更好，而且更容易安装。

hey manual

./bin/hey_linux_amd64 -h
flag needs an argument: -h
Usage: hey [options...] <url>
Options:
-n Number of requests to run. Default is 200.
-c Number of workers to run concurrently. Total number of requests cannot
be smaller than the concurrency level. Default is 50.
-q Rate limit, in queries per second (QPS) per worker. Default is no rate limit.
-z Duration of application to send requests. When duration is reached,
application stops and exits. If duration is specified, n is ignored.
Examples: -z 10s -z 3m.
-o Output type. If none provided, a summary is printed.
"csv" is the only supported alternative. Dumps the response
metrics in comma-separated values format.
-m HTTP method, one of GET, POST, PUT, DELETE, HEAD, OPTIONS.
-H Custom HTTP header. You can specify as many as needed by repeating the flag.
For example, -H "Accept: text/html" -H "Content-Type: application/xml" .
-t Timeout for each request in seconds. Default is 20, use 0 for infinite.
-A HTTP Accept header.
-d HTTP request body.
-D HTTP request body from file. For example, /home/user/file.txt or ./file.txt.
-T Content-type, defaults to "text/html".
-U User-Agent, defaults to version "hey/0.0.1".
-a Basic authentication, username:password.
-x HTTP Proxy address as host:port.
-h2 Enable HTTP/2.
-host HTTP Host header.
-disable-compression Disable compression.
-disable-keepalive Disable keep-alive, prevents re-use of TCP
connections between different HTTP requests.
-disable-redirects Disable following of HTTP redirects
-cpus Number of used cpu cores.
(default for current machine is 8 cores)

举几个例子

./bin/hey_linux_amd64 -z 10m http://127.0.0.1:50000

持续发10min无限发压

./bin/hey_linux_amd64 -c 10 -n 10000 http://127.0.0.1:50000

10并发发10000个请求

代码写的是短小精悍，但唯一是不足是没法看指标的一个变化曲线，比如我要看服务的性能瓶颈，到达什么量级系统压不上去、请求量多少时候机器性能有问题等。因此接入Prometheus + Grafana十分有必要的。

Prometheus 是一个开源的服务监控系统和时间序列数据库， 提供监控数据存储，展示，告警等功能。

Grafana 是一个用于监控指标分析和图表展示的工具， 后端支持 Graphite, InfluxDB & Prometheus & Open-falcon等， 它是一个流行的监控组件， 目前在各大中小型公司中广泛应用

如何使用

环境准备可参考

medium.com/geekculture/monitoring-...

注意：忽略blackbox setup步骤

• 安装Prometheus

  
  

• 配置prometheus.yml

  
  

# my global config
global:
scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
# scrape_timeout is set to the global default (10s).
# Alertmanager configuration
alerting:
alertmanagers:
- static_configs:
- targets:
# - alertmanager:9093
# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
# - "first_rules.yml"
# - "second_rules.yml"
# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
# The job name is added as a label `job=` to any timeseries scraped from this config.
- job_name: "prometheus"
# metrics_path defaults to '/metrics'
# scheme defaults to 'http'.
static_configs:
- targets: ["localhost:9090"]
- job_name: "hey"
scrape_interval: 1s
static_configs:
- targets: ['localhost:1010']

注意端口1010是写死的，后续计划修改成可以通过命令行进行随机赋值

• 安装Grafana

最终效果如下~

选取几个进行展示

注意：只有hey压测起来后，才可以采集到相关数据
