The Prometheus *blackbox_exporter* is a tool that can perform arbitrary, generic ICMP, TCP, or HTTP "probes" against external services. This is useful for applications that do not export their own metrics, and for evaluating the health of protocol-level operations (e.g. TLS certificate expiration). The *blackbox-exporter* Ansible role installs and configures the Blackbox Exporter on the target system. It fetches the specified binary release from Github and copies it to the remote machine. It also creates a systemd unit and configures the Blackbox exporter's "modules" from the `blackbox_modules` Ansible variable.
