# Linux CPU Input Plugin
This plugin gathers CPU metrics exposed on [Linux][kernel] systems.
⭐ Telegraf v1.24.0
🏷️ system
💻 linux
[kernel]: https://kernel.org/
## Global configuration options <!-- @/docs/includes/plugin_config.md -->
In addition to the plugin-specific configuration settings, plugins support
additional global and plugin configuration settings. These settings are used to
modify metrics, tags, and field or create aliases and configure ordering, etc.
See the [CONFIGURATION.md][CONFIGURATION.md] for more details.
[CONFIGURATION.md]: ../../../docs/CONFIGURATION.md#plugins
## Configuration
```toml @sample.conf
# Provides Linux CPU metrics
# This plugin ONLY supports Linux
[[inputs.linux_cpu]]
## Path for sysfs filesystem.
## See https://www.kernel.org/doc/Documentation/filesystems/sysfs.txt
## Defaults:
# host_sys = "/sys"
## CPU metrics collected by the plugin.
## Supported options:
## "cpufreq", "thermal"
## Defaults:
# metrics = ["cpufreq"]
```
## Metrics
The following tags are emitted by the plugin under the name `linux_cpu`:
| Tag | Description |
|-------|-----------------------|
| `cpu` | Identifier of the CPU |
The following fields are emitted by the plugin when selecting `cpufreq`:
| Metric name (field) | Description | Units |
|---------------------|------------------------------------------------------------|-------|
| `scaling_cur_freq` | Current frequency of the CPU as determined by CPUFreq | KHz |
| `scaling_min_freq` | Minimum frequency the governor can scale to | KHz |
| `scaling_max_freq` | Maximum frequency the governor can scale to | KHz |
| `cpuinfo_cur_freq` | Current frequency of the CPU as determined by the hardware | KHz |
| `cpuinfo_min_freq` | Minimum operating frequency of the CPU | KHz |
| `cpuinfo_max_freq` | Maximum operating frequency of the CPU | KHz |
The following fields are emitted by the plugin when selecting `thermal`:
| Metric name (field) | Description | Units |
|-----------------------|-------------------------------------------------------------|-------|
| `throttle_count` | Number of thermal throttle events reported by the CPU | |
| `throttle_max_time` | Maximum amount of time CPU was in throttled state | ms |
| `throtlle_total_time` | Cumulative time during which the CPU was in throttled state | ms |
