修改针对API错误的Prometheus指标

Question

我正在使用以下方法调用每个api。

有一个如下所示的控件，我正在调用“ / my”以获取api的响应

   @GetMapping(value = {"/my"}, produces = APPLICATION_JSON_VALUE)
      public ResponseEntity<String> my(HttpServletResponse httpServletResponse,HttpServletRequest httpServletRequest)
  ResponseEntity<String> iapiResponse = apiServices.getJsonResponse(iapi,
                  I_API, HttpMethod.GET,
                  new HttpEntity<String>(Utilities.getHeaders(httpServletRequest)),
                  httpServletRequest);

            return iapiResponse

内部呼叫

 private ResponseEntity<String> getJsonResponse(String url,
                                                      String apiName,
                                                      HttpMethod httpMethod,
                                                      HttpEntity<String> httpEntity,
                                                      HttpServletRequest httpServletRequest)
    {
        httpServletRequest.setAttribute("api", apiName);
        ResponseEntity<String> itemResponseEntity = null;
        try {
            itemResponseEntity = restTemplate.exchange(url, httpMethod, httpEntity, String.class);
        } catch (Exception e) {

            throw new LocalHttpClientErrorException(e.getLocalizedMessage());
        }
        return itemResponseEntity;
    }

在普罗米修斯，度量标准为

http_server_requests_seconds_sum {exception =“ LocalHttpClientErrorException”，method =“ GET”，outcome =“ SERVER_ERROR”，status =“ 502”，uri =“ / my”，} 0.740494179

我想修改它并添加apiName，这样我就可以知道哪个api导致了此错误

http_server_requests_seconds_count {exception =“ LocalHttpClientErrorException”，method =“ GET”，outcome =“ SERVER_ERROR”，status =“ 502”，uri =“ / my”，api =“ iapi”} 18.0

我该如何实现？
