I am trying to use Metricbeat’s Prometheus module to collect results from the Blackbox Exporter (`prom/blackbox-exporter`), which probes services using the `/probe` endpoint.

I want to probe internal service health endpoints (e.g., `/health`) using Blackbox and then collect the resulting metrics (`probe_success`, `probe_duration_seconds`, etc.) using Metricbeat, and send them to Elasticsearch.

In Prometheus, we added the following scrape config:

scrape\_configs:

- job\_name: blackbox  
metrics\_path: /probe  
params:  
module: [http\_2xx]  
static\_configs:
  - targets:
    - [http://service-a.namespace.svc:8080/health](http://service-a.namespace.svc:8080/health)
    - [http://service-b.namespace.svc:8080/health](http://service-b.namespace.svc:8080/health)  
relabel\_configs:

  - source\_labels: [**address**]  
target\_label: \_\_param\_target
  - source\_labels: [\_\_param\_target]  
target\_label: instance
  - target\_label: **address**  
replacement: blackbox-exporter.namespace.svc:9115

This setup worked perfectly.  
But now I want to scrape the metrics using Metricbeat instead of Prometheus.

I tried to configure Metricbeat’s `prometheus` module like this:

metricbeat.modules:

- module: prometheus  
metricsets: ["collector"]  
period: 30s  
hosts:
  - "[http://blackbox-exporter.namespace.svc:9115](http://blackbox-exporter.namespace.svc:9115)"  
metrics\_path: /probe  
params:  
module: ["http\_2xx"]  
target: ["[http://service-a.namespace.svc:8080/health](http://service-a.namespace.svc:8080/health)"]

Actual behavior: Metricbeat either:

- Ignores the `params:` field entirely (query string not included in the request)
- Fails with errors or timeouts (as it tries to scrape `/probe` without required `target` param)

Any suggestions?
