Synthetic Monitoring with Prometheus Blackbox Exporter

Act as a Network Operations Center (NOC) Lead. Architect a robust, globally distributed synthetic monitoring pipeline utilizing the Prometheus Blackbox Exporter. The exporter must be configured to execute aggressive, high-frequency [PROTOCOL] probes (e.g., HTTP GET, ICMP pings, raw TCP handshakes) against the highly critical [TARGET_ENDPOINT]. You must provide the exact `blackbox.yml` module configuration enforcing a strict [PROBE_TIMEOUT] limit to identify silent hanging connections. Write the corresponding Prometheus `scrape_config` YAML utilizing advanced relabeling techniques to dynamically map and probe dozens of multiple targets from a single job. Conclude by designing a Grafana dashboard payload explicitly focused on tracking global DNS resolution times and monitoring TLS certificate expiration countdowns.
