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

This plugin normalizes voltage sensor names during service discovery. As a result, existing services may be renamed (for example, Voltage Voltage 1V2 becomes Voltage 1V2). After upgrading from the original checkpoint_voltage check, a service discovery should be performed on affected hosts to remove obsolete services and create the new ones. See on github for detail.

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:
  • Voltage values can be exported as performance data
  • Enables metric collection and graphing in Checkmk
• Improved service naming:
  • Removes redundant occurrences of "Voltage" from sensor names
  • Prevents duplicate service names such as Voltage Voltage 0V99
