This check monitors fan sensors in Check Point firewalls. It is an enhanced replacement for the original Checkmk check checkpoint_fan.

This plugin removes unused fans. After upgrading from the original "checkpoint_fan" check, service discovery should be performed on the affected hosts to remove obsolete services. See github for details.

Improvements over the original check

• Configurable state handling:
  • Out-of-range conditions can be mapped to the desired Checkmk state (default: CRIT)
  • Sensor reading errors can be mapped to the desired Checkmk state (default: UNKNOWN)
• Optional performance data
• Removed unused fans
