Blackbox Exporter Machine Charm

Performs ICMP connectivity checks of its peers by default and supports blackbox probing with a variety of protocols.

Blackbox Exporter is a Juju subordinate charm that deploys and manages the Prometheus Blackbox Exporter snap on machines such as LXD, enabling blackbox probing of endpoints over HTTP(S), DNS, TCP, and ICMP. It is a complementary charm to the Canonical Observability Stack (COS), allowing operators to monitor the reachability and responsiveness of external services: https://documentation.ubuntu.com/observability

Probe configurations are provided via Juju config or through the probes relation, and are automatically registered as Prometheus scrape jobs.

Key features:

• Blackbox probing over multiple protocols: HTTP(S), DNS, TCP, and ICMP.
• Automatic probe registration as Prometheus scrape jobs via Juju relations.
• Built-in Grafana dashboards and Prometheus alert rules for self-monitoring.
• Seamless integration with Prometheus, Grafana, and Loki through Juju relations.
