How disable RestTemplate monitoring

[chendy560]

There are many such codes in my system:

    public void doSomething(String id) {
        URI uri = UriComponentsBuilder.fromHttpUrl("http://...").queryParam("id", id).build().encode().toUri();
        RequestEntity<Void> request = RequestEntity.get(uri).build();
        restTemplate.exchange(request, SomeThing.class);
        //...
    }

Each different id will bring a different URI, as well as a new tag. It will take up a lot of memory, so how disable it?

Why don't you use the rest template it URI templates?

Sorry, I did not know it before😂
It works, thanks

@spencergibb Code I am working on cannot be easily refactored. Is there a way to turn off metric gathering for a particular RestTemplate bean?

I am using the code below to customize the RestTemplate

new MetricsRestTemplateCustomizer( meterRegistry, ( urlTemplate, request, response ) ->
  Arrays.asList(
      RestTemplateExchangeTags.method(request),
      RestTemplateExchangeTags.status(response),
      RestTemplateExchangeTags.clientName(request)
  ), 
  "myTestMetric"
)
.customize( restTemplate );

This creates a metric called myTestMetric and it does not record the URI, just like I wanted. However the automatically generated http_client_requests_seconds_* are still being recorded.

Each request would generate a new metric as the url is very complex.

I fixed my problem creating the following @Bean:

    @Bean
    RestTemplateExchangeTagsProvider restTemplateExchangeTagsProvider() {

        new RestTemplateExchangeTagsProvider() {
            @Override
            Iterable<Tag> getTags( String urlTemplate, HttpRequest request, ClientHttpResponse response ) {

                Tag uriTag

                if ( StringUtils.hasText( urlTemplate ) ) {
                    uriTag = RestTemplateExchangeTags.uri( urlTemplate )
                } else if ( request.URI.path.startsWith( '/faulty-endpoint' ) ) {
                    uriTag = RestTemplateExchangeTags.uri( request.URI.path )
                } else {
                    uriTag = RestTemplateExchangeTags.uri( request )
                }

                [ RestTemplateExchangeTags.method( request ),
                  uriTag,
                  RestTemplateExchangeTags.status( response ),
                  RestTemplateExchangeTags.clientName( request ) ]
            }
        }
    }

If the URI.path starts with /faulty-endpoint, it will tag the URI.path instead of the full URI with all parameters.

The above is simply a slightly modified version of the DefaultRestTemplateExchangeTagsProvider

                } else if ( request.URI.path.startsWith( '/faulty-endpoint' ) ) {
                    uriTag = RestTemplateExchangeTags.uri( request.URI.path )
                } else {
                    uriTag = RestTemplateExchangeTags.uri( request )
                }

                [ RestTemplateExchangeTags.method( request ),
                  uriTag,
                  RestTemplateExchangeTags.status( response ),
                  RestTemplateExchangeTags.clientName( request ) ]
            }
        }
    }

I am calling a third party API for logging the metrics
the URI is like "/api/xxx/123" the last 3 digits are changes
my requirement is to count the trigger for "/api/xxx" for this metrics
I have other api call that i don't want to change I am using spring boot (RestTemplate) and the configuration is global
any suggestion how can i do this.

@chandreshlko I'm not understanding exactly what you're trying to accomplish. It will probably be easier to figure this out through chat. Feel free to join us on Slack at https://slack.micrometer.io.

[faramarzaf]

@chandreshlko and @shakuzen I have the same problem, I am invoking rest API that has a path variable like this -> /api/{id}
but I don't want to log /{id} part by each request send to 3rd party because of the high request rate which leads to using more space. Is there any solution to exclude the specific path? I mean something like bucket metric for Rest controllers?

[bclozel]

@faramarzaf can you ask this question on StackOverflow? Please add to your question the relevant information like: which spring boot version you are using, how are you creating and using the rest template instance, show which metrics are collected.
