An organization runs Prometheus with Alertmanager. They have two teams: 'platform' and 'application'. The platform team wants alerts for infrastructure issues (e.g., node down) sent to their Slack channel. The application team wants alerts for application errors sent to their email list. All alerts are currently routed to a single default receiver. What is the minimal configuration change to route alerts to the correct receivers based on the alert's team label?

Modify the Prometheus alerting rules to include a 'receiver' label that Alertmanager uses directly.

Create two separate Alertmanager instances, one for each team, and configure Prometheus to send alerts to both.

Add a route in Alertmanager's config with match labels for 'team=platform' and 'team=application', each pointing to a different receiver.

Use a single receiver and add a webhook that forwards alerts to both Slack and email based on the team label.

A DevOps engineer is configuring Prometheus to scrape metrics from a set of application instances that expose metrics on port 9100 with a path of /metrics. The instances are identified by the label 'app' with values 'api' or 'worker'. The engineer wants to scrape both groups in a single job but apply a longer scrape interval (60s) to the 'worker' instances than to the 'api' instances (15s). Which configuration approach achieves this?

Define one scrape job with scrape_interval: 15s and set 'scrape_timeout: 60s' for the 'worker' targets via relabeling.

Define one scrape job with scrape_interval: 15s and use relabeling to drop the 'worker' targets, then add a second job for 'worker' with 60s.

Define two separate scrape jobs in prometheus.yml, each with its own scrape_interval, and use static_configs to list the respective targets.

Define one scrape job with scrape_interval: 15s and use metric_relabel_configs to adjust the interval for 'worker' metrics.
