O que o DumbMonit vigia
Any exporter that serves the Prometheus text format: node_exporter, windows_exporter, cAdvisor, blackbox_exporter, smartctl_exporter, a database exporter, or one you wrote. DumbMonit reads its /metrics page on every check and stores each series, so it shows up in the explorer and the graphs and can be used in threshold rules.
Uso típico. Any exporter (node_exporter, windows_exporter, cAdvisor, blackbox…): every series stored, graphed and usable in rules

Etapas de configuração: Point DumbMonit at the exporter
Check that the exporter answers from the DumbMonit host.
curl http://server.lan:9100/metricsIn DumbMonit, enter the host and pick the exporter, or leave custom and give the port.
Optional: restrict what is stored with Keep only or Ignore, to keep a large exporter within the series limit.
Optional: if the exporter is on another site, choose a relay agent to read it from there.
Atenção. Metrics pages are usually unauthenticated: filter the port so that only the DumbMonit host reaches it.
