categraf使用input.prometheus，配置consul服务发现，无法采集数据

prometheus.toml内容如下：

# # collect interval
# interval = 15

[[instances]]
#urls = [
#     "http://localhost:19000/metrics"
#]

#url_label_key = "instance"
#url_label_value = "{{.Host}}"

#url_label_pair = {instance="{{.Host}}", alarmObject="{{.Host}}"}

## metrics duplication allowed, default false
#  duplication_allowed=true

## Scrape Services available in Consul Catalog
 [instances.consul]
   enabled = true
   agent = "http://127.0.0.1:8500"
   query_interval = "1m"

   [[instances.consul.query]]
     name = "custom_exporter"
     tag = "custom_exporter"
     url = 'http://{{.ServiceAddress}}:{{.ServicePort}}/metrics'
     [instances.consul.query.tags]
       host = "{{.Node}}"
