hey工具魔改

# 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 ```bash ./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](https://prometheus.io/) + [Grafana](https://grafana.com/)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 修改patch https://github.com/rickzhen/hey/commit/15e4febda47749aa3683820d705be237ed7d420e ## 如何使用 环境准备可参考 https://medium.com/geekculture/monitoring-websites-using-grafana-and-prometheus-69ccf936310c 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=<job_name>` 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 - 引用数据，具体数据项如下 ``` # HELP hey_average_latency hey average lantency of all requests # TYPE hey_average_latency gauge hey_average_latency 0.333023128238458 # HELP hey_avg_conn hey average lantency of connection setup(DNS lookup + Dial up) # TYPE hey_avg_conn gauge hey_avg_conn 0.0008299568803227264 # HELP hey_avg_delay hey average lantency between response and request # TYPE hey_avg_delay gauge hey_avg_delay 0.3276944901389514 # HELP hey_avg_dns hey average lantency of dns lookup # TYPE hey_avg_dns gauge hey_avg_dns 0 # HELP hey_avg_req hey average lantency of request "write" # TYPE hey_avg_req gauge hey_avg_req 9.923097265800088e-05 # HELP hey_avg_res hey average lantency of response "read" # TYPE hey_avg_res gauge hey_avg_res 0.004199986732406999 # HELP hey_fastest hey minimum lantency of all requests # TYPE hey_fastest gauge hey_fastest 0.0153465 # HELP hey_fastest_conn hey minimum lantency of connection setup(DNS lookup + Dial up) # TYPE hey_fastest_conn gauge hey_fastest_conn 0.0002317 # HELP hey_fastest_delay hey minimum lantency between response and request # TYPE hey_fastest_delay gauge hey_fastest_delay 0.007162 # HELP hey_fastest_dns hey minimum lantency of dns lookup # TYPE hey_fastest_dns gauge hey_fastest_dns 0 # HELP hey_fastest_req hey minimum lantency of request "write" # TYPE hey_fastest_req gauge hey_fastest_req 1.84e-05 # HELP hey_fastest_res hey minimum lantency of response "read" # TYPE hey_fastest_res gauge hey_fastest_res 7.03e-05 # HELP hey_num_res hey num of all requests # TYPE hey_num_res gauge hey_num_res 2231 # HELP hey_rps hey request of per second # TYPE hey_rps gauge hey_rps 148.46734517640908 # HELP hey_slowest_conn hey maximum lantency of connection setup(DNS lookup + Dial up) # TYPE hey_slowest_conn gauge hey_slowest_conn 0.0764439 # HELP hey_slowest_delay hey maximum lantency between response and request # TYPE hey_slowest_delay gauge hey_slowest_delay 0.6143227 # HELP hey_slowest_dns hey maximum lantency of dns lookup # TYPE hey_slowest_dns gauge hey_slowest_dns 0 # HELP hey_slowest_req hey maximum lantency of request "write" # TYPE hey_slowest_req gauge hey_slowest_req 0.0123371 # HELP hey_slowest_res hey maximum lantency of response "read" # TYPE hey_slowest_res gauge hey_slowest_res 0.1017448 # HELP hey_slowtest hey maximum lantency of all requests # TYPE hey_slowtest gauge hey_slowtest 0.6210238 ``` ## the end 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 最后感谢rakyll~ 项目地址：https://github.com/rickzhen/hey 下载地址：https://github.com/rickzhen/hey/releases 如果对你有帮助的话，辛苦给个star鸭~ 如有问题可以提issue，也可以在评论区互相交流。
