metrics metadata can inherit from job

[zhangjianweibj]

prometheus verison:last

issue: metrics get from prometheus should inherit metadata from scrape job.or users can config the feature.in this situation，prometheus pull meric from client can reduce additional label and reduce network burden.what is more,users can use prometheus more flexibly and effectively.

for example,i want every metric samples get from prometheus hava lables service_id and service_port,how to achieve this goal?

You can use the relabel_config to replace the __meta_ label as a normal label.

example

relabel_configs:
- source_labels: [__meta_consul_node]
  separator: ;
  regex: (.*)
  target_label: node
  replacement: $1
  action: replace
- source_labels: [__meta_consul_service]
  separator: ;
  regex: (.*)
  target_label: consul_service
  replacement: $1
  action: replace
- source_labels: [__meta_consul_tag]
  separator: ;
  regex: (.*)
  target_label: consul_tag
  replacement: $1
  action: replace
- source_labels: [__meta_consul_dc]
  separator: ;
  regex: (.*)
  target_label: consul_dc
  replacement: $1
  action: replace
- source_labels: [__meta_consul_service_port]
  separator: ;
  regex: (.*)
  target_label: consul_service_port
  replacement: $1
  action: replace
