error orccured during parsing service discovery file.

- prometheus.yml

global:

  scrape_interval:     3s

  evaluation_interval: 3s

rule_files:

  # - "first.rules"

  # - "second.rules"

scrape_configs:

  - job_name: prometheus

    static_configs:

      - targets: ['localhost:9090']

  - job_name: node_exporter

    file_sd_configs:

      - files:

        - '/Users/skynet/prometheus/server/sd.yml'

- sd.yml

targets:

  - "localhost:9100/metrics"

  

labels:

  - ensemble: ["127.0.0.1:2181"]

  - service_code: "test"

  - node: ["127.0.0.1:11211", "127.0.0.1:11212"]

when I run prometheus, this error is occured.

msg="Error reading file" path=/Users/skynet/prometheus/server/sd.yml err="yaml: unmarshal errors:\n  line 1: cannot unmarshal !!map into []*targetgroup.Group"

How can i fix?

Firstly, the top level of the targets file must be a list, which means "bullet points" required at the top:

- targets: ...
  labels: ...

- targets: ...
  labels: ...

Secondly, the labels themselves can only be strings, not lists.

- targets:

    - "localhost:9100/metrics"

  labels:

    - ensemble: "127.0.0.1:2181"

    - service_code: "test"

    - node: "127.0.0.1:11211"

You can't have two values for the label "node".
