# dev.cpu.0.freq
Plugin: freebsd.plugin
Module: dev.cpu.0.freq
## Overview
Read current CPU Scaling frequency.
Current CPU Scaling Frequency
This collector is supported on all platforms.
This collector supports collecting metrics from multiple instances of this integration, including remote instances.
### Default Behavior
#### Auto-Detection
This integration doesn't support auto-detection.
#### Limits
The default configuration for this integration does not impose any limits on data collection.
#### Performance Impact
The default configuration for this integration is not expected to impose a significant performance impact on the system.
## Metrics
Metrics grouped by *scope*.
The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
### Per dev.cpu.0.freq instance
The metric shows status of CPU frequency, it is direct affected by system load.
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|:------|:----------|:----|
| cpu.scaling_cur_freq | frequency | MHz |
## Alerts
There are no alerts configured by default for this integration.
## Setup
### Prerequisites
