Prometheus NUT Exporter v1.2.0

Added

• Added metrics (@uncleBorsch):
  • nut_temperature_celsius (ups.temperature)
  • nut_delay_shutdown_seconds (ups.delay.shutdown)
  • nut_delay_start_seconds (ups.delay.start)
  • nut_battery_voltage_high_volts (battery.voltage.high)
  • nut_battery_voltage_low_volts (battery.voltage.low)
• Added more UPS metadata (@uncleBorsch).
• Added support for binding to a specific IP address through the HTTP_ADDRESS environment variable (@nsapa).
• Added metric nut_ups_status as a state set with support for many UPS statuses (OL, OB, LB, CHRG etc.).
• Added labels driver_version, driver_version_internal, driver_version_data and manufacturing_date to the nut_ups_info metric.
• Added proper signal handling to shutdown gracefully and not hang.
• Added multi-architecture support (Docker images for different architectures will get published to Docker Hub).

Changed

• Changed default log level to info.
• Made the target port default to 3493 instead of requiring one to be provided.
• Made the Prometheus/OpenMetrics output (more) OpenMetrics 1.0.0-compliant.

Deprecated

• Deprecated nut_info and added nut_server_info as an identical but better named replacement.
• Deprecated nut_status as it has very limited support for UPS statuses and doesn't always work as intended. See nut_ups_status for the replacement.
• Deprecated the type and nut_version labels from the nut_ups_info metric. Use device_type and driver_version instead.
• Deprecated nut_battery_volts, nut_input_volts and nut_output_volts. Replacements were added in v1.1.0.

Removed

• Removed the tini init system from the Docker image, since signals are handled properly now.

Fixed

• Fixed typo in the device.mfr variable (@nsapa).
