```
## 运行
1. 执行如下脚本触发指标的采集
```
http://localhost:8080/items
```
```
# TYPE web_reqeust_total counter
web_reqeust_total{endpoint="/items",method="GET"} 1
# HELP web_request_duration_seconds web request duration distribution
# TYPE web_request_duration_seconds histogram
web_request_duration_seconds_bucket{endpoint="/items",method="GET",le="0.1"} 1
web_request_duration_seconds_bucket{endpoint="/items",method="GET",le="0.3"} 1
web_request_duration_seconds_bucket{endpoint="/items",method="GET",le="0.5"} 1
web_request_duration_seconds_bucket{endpoint="/items",method="GET",le="0.7"} 1
web_request_duration_seconds_bucket{endpoint="/items",method="GET",le="0.9"} 1
web_request_duration_seconds_bucket{endpoint="/items",method="GET",le="1"} 1
web_request_duration_seconds_bucket{endpoint="/items",method="GET",le="+Inf"} 1
web_request_duration_seconds_sum{endpoint="/items",method="GET"} 0.0010157
web_request_duration_seconds_count{endpoint="/items",method="GET"} 1
```
