要测试使用 Beyla 采集服务的 REDRate-Errors-Duration 指标那首先得有个服务这里我用的是 answer https://answer.flashcat.cloud 论坛你也可以自己搞一个简单的 http 服务比如
package mainimport (net/httpstrconvtime
)func handleRequest(rw http.ResponseWriter, req *http.Request) {status : 200for k, v : range req.URL.Query() {if len(v) 0 {continue}switch k {case status:if s, err : strconv.Atoi(v[0]); err nil {status s}case delay:if d, err : time.ParseDuration(v[0]); err nil {time.Sleep(d)}}}rw.WriteHeader(status)
}func main() {http.ListenAndServe(:8080,http.HandlerFunc(handleRequest))
}上面这个代码保存成 server.go然后用 go run server.go 即可运行当然前提是你机器上有 go 开发环境。这个小服务可以接收两个参数一个是 status用来指定返回的 http 状态码另一个是 delay用来指定延迟多久返回比如
curl -v http://localhost:8080/foo?status404上面的命令会返回 404 状态码如果想延迟 1 秒返回可以这样
curl -v http://localhost:8080/foo?delay1s接下来我们就可以使用 Beyla 采集这个服务的 RED 指标了。
下载 Beyla
我的机器上有 go 开发环境所以我直接使用 go install 安装了你也可以去 Beyla 的 release 页面下载二进制包然后解压缩使用。
go install github.com/grafana/beyla/cmd/beylalatest运行 Beyla
使用下面的命令运行 Beyla
$ BEYLA_PROMETHEUS_PORT8999 PRINT_TRACEStrue OPEN_PORT8080 sudo -E beyla或者直接使用 root 账号运行比如我是这么跑的
$ BEYLA_PROMETHEUS_PORT8999 PRINT_TRACEStrue OPEN_PORT8080 beyla解释一下这几个参数
BEYLA_PROMETHEUS_PORT: Beyla 要监听的端口通过这个端口暴露 metrics 指标数据PRINT_TRACES: 是否打印 trace 日志OPEN_PORT: Beyla 采集的目标服务监听的端口这里是 8080上面给出的那段 go server 的代码就是监听在 8080我的机器上 answer 论坛程序也是监听在 8080你要监控的程序如果不是监听在 8080可以在换成你自己的端口
查看指标
运行之后可以通过 curl 查看指标
curl http://localhost:8999/metrics返回的内容如下

结语
Beyla 目前还不太稳定还有很多功能没有完成。不过可以尝鲜研究了。可观测性整套技术栈搞起来还挺费劲的如果您想建设这套技术栈欢迎来和我们聊聊我们提供这方面的咨询和商业产品详情了解
