error loading config from prometheus yml couldn t load configuration --config file prometheus yml parsing YAML file prometheus yml yaml unmarshal errors

Question

Hi Guys,

I am trying to start Prometheus server in my system, but I am getting some error as shown below.

$ ./prometheus
level=error ts=2020-05-27T06:42:06.463Z caller=main.go:758 err="error loading config from \"prometheus.yml\": couldn't load configuration (--config.file=\"prometheus.yml\"): parsing YAML file prometheus.yml: yaml: unmarshal errors:\n  line 30: field static_configs already set in type config.plain"

I used this below configuration file.

scrape_configs:
- job_name: 'prometheus'
  static_configs:
  - targets: ['localhost:9090']
  static_configs:
  - targets: ['10.0.2.15:9100']

 Can anyone help me with this?

Hi@akhtar,

Whenever you add any node to scrape its metrics, you have to give job name for individuals. In your code you missed job name. Correct your configuration file as given below.

scrape_configs:
- job_name: 'prometheus'
  static_configs:
  - targets: ['localhost:9090']
- job_name: 'Node1'
  static_configs:
  - targets: ['10.0.2.15:9100']

Now it will not give any error.
