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'
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'
This should work better for you:
- job_name: samplejob
metrics_path: /api/queues
params:
columns: [name,messages]
static_configs:
- targets:
- localhost:15672
