Prometheus Configuration Acquisition Target

1. Scraping periodically at http/s (scrape/pull) according to the configuration task (job)
2. The metric on the target. Target
3. It can be specified statically or automatically. Prometheus saves scrape metric s on local or remote storage.

Define the acquisition target using scrape_configs
Configure a series of targets and how to grab their parameters. In general, each scrape_config corresponds to a single Job.
Targets can be statically configured in scrape_config or dynamically discovered using a service discovery mechanism.
