}
- 启动go服务
go run test.go
go run test2.go
-
访问ip+8085地址
-
多请求一点数据让skywalking数据展示出来
for i in {1..100};do sleep 2; hey -n 100 -m get http://192.168.10.100:8085 ;done
- php-fpm容器接入skywalking
docker pull skyapm/skywalking-php:v4.2.0-7.2-fpm-alpine

重启docker php-fpm容器并访问8080/2.php
页面显示test 8085 因为访问的8085的接口 -
查看skywalking是否监控到了php
