Blackbox Exporter

Blackbox Exporter is an open-source network probing and monitoring tool designed to test the availability and performance of endpoints such as HTTP, HTTPS, TCP, DNS, and ICMP. It exposes metrics in a Prometheus-compatible format, allowing developers and DevOps teams to monitor uptime, response time, SSL certificate expiry, and service health programmatically. Blackbox Exporter is ideal for backend monitoring, DevOps pipelines, and integration with visualization tools like Grafana for dashboards and alerting.

• Exposes metrics compatible with Prometheus for monitoring and alerting.
• Provides detailed metrics such as probe duration, HTTP status codes, DNS lookup time, and SSL certificate expiry.
