Process Stats

Module: process_stats (default)
API Endpoint: /machine/proc_stats

Collects Moonraker process statistics and system-level CPU, memory, and uptime metrics from the Klipper host.

Metrics

Metric	Type	Description
klipper_moonraker_cpu_usage	Gauge	Moonraker process CPU usage
klipper_moonraker_memory_kb	Gauge	Moonraker process memory usage in KB
klipper_moonraker_websocket_connections	Gauge	Number of active Moonraker websocket connections
klipper_system_cpu	Gauge	System-wide CPU usage percentage
klipper_system_cpu_temp	Gauge	System CPU temperature in Celsius
klipper_system_memory_available	Gauge	Available system memory
klipper_system_memory_total	Gauge	Total system memory
klipper_system_memory_used	Gauge	Used system memory
klipper_system_uptime	Counter	System uptime in seconds
klipper_system_throttled_bits	Gauge	Throttled state bitmask from the Raspberry Pi firmware
klipper_system_throttled_flag_info	Gauge=1	Active throttled state flags with flag label

Example PromQL

# Moonraker memory usage over time
klipper_moonraker_memory_kb

# System CPU temperature
klipper_system_cpu_temp

# System uptime in days
klipper_system_uptime / 86400

# Throttled state (non-zero means throttling occurred)
klipper_system_throttled_bits

# Active throttling flags (e.g., under-voltage, frequency capped)
