Collecting simple Prometheus metrics from a host remotely.

Useful for ensuring a host is up with the proper ports open when you cannot run a regular exporter on the host

Metrics

• Host up (ping)
• Ports open (nmap)

Metrics are available from http://hostname:9100/metrics

Building/running

Build and run scripts are in the ./scripts directory

Configuring

edit ./src/config.yml

Example:

debug: false
refresh_rate: 120  # seconds before scanning hosts again
hosts:  # list of hosts to gather metrics on
- localhost

Helm

The service is not going to be externally available. It should be deployed in the same namespace as Prometheus.
