Selective scraping

It is possible to pass an optional list of job names to filter out metrics as query parameters. This might be useful for scraping targets with different intervals or any other advanced use cases, when calling all jobs at once is undesired.

The jobs[] query parameter may be used multiple times. The resulted HTTP request would look like this:

GET /metrics?jobs[]=db_targets1&jobs[]=db_targets2

In Prometheus configuration we can use this syntax under the scrape config:

params:
  jobs[]:
    - db_targets1
    - db_targets2
