Prometheus metrics_path gets encoded

Question

URL:localhost:15672/api/queues?columns=name,messages

Result: localhost:15672/api/queues%3Fcolumns=name,messages

Prometheus the '?' gets encoded to '%3F' and therefore the request fails

Can you write the result?

    static_configs:
  - targets: ['localhost:15672']
metrics_path: '/api/queues?columns=name,messages'

Answer 1

You have to use the params configuration of the scrape config.

# Optional HTTP URL parameters.
params:
  [ <string>: [<string>, ...] ]

In your case:

static_configs:
- targets: ['localhost:15672']
  metrics_path: '/api/queues'
  params:
     columns:'name,messages'
