f2bne

Go program that exports f2b status logs into node exporter. Metrics are dumped on standard output.

The following metrics are dumped:

• f2bne_last_run_timestamp_seconds <epoch> (gauge)
• f2bne_run_duration_seconds <duration> (gauge)
• f2bne_failed_count_total{jail="<jail>"} <num> (counter)
• f2bne_banned_count_total{jail="<jail>"} <num> (counter)

Nodeexporter Exporters

Generally we want node-exporter exporter to follow the following rules:

• accept a -t flag to tells it how often we expect it to run. This flag's value in only used in the metrics.
• accept a -w flag that tells it to write to /var/lib/prometheus/node-exporter/<basename>.prom
• at least have the following metrics:
  • <name>_last_run_timestamp_seconds <epoch> - when did we run
  • <name>_run_duration_seconds <duration> - the value of -t

All NEs are packaged in cncz-ne package.
