# HDD temperature

Plugin: go.d.plugin
Module: hddtemp

## Overview

This collector monitors disk temperatures.


It retrieves temperature data for attached disks by querying the hddtemp daemon at regular intervals.


This collector is only supported on the following platforms:

- Linux

This collector supports collecting metrics from multiple instances of this integration, including remote instances.


### Default Behavior

#### Auto-Detection

By default, this collector will attempt to connect to the `hddtemp` daemon on `127.0.0.1:7634`

#### 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 disk

These metrics refer to the Disk.

Labels:

| Label      | Description     |
|:-----------|:----------------|
| disk_id | Disk identifier. It is derived from the device path (e.g. sda or ata-HUP722020APA330_BFJ0WS3F) |
| model | Disk model |

Metrics:

| Metric | Dimensions | Unit |
|:------|:----------|:----|
| hddtemp.disk_temperature | temperature | Celsius |
| hddtemp.disk_temperature_sensor_status | ok, err, na, unk, nos, slp | status |



## Alerts

There are no alerts configured by default for this integration.


## Setup

### Prerequisites

#### Install hddtemp

Install `hddtemp` using your distribution's package manager.



### Configuration

#### File

The configuration file name for this integration is `go.d/hddtemp.conf`.


You can edit the configuration file using the `edit-config` script from the
Netdata [config directory](/docs/netdata-agent/configuration/README.md#the-netdata-config-directory).

```bash
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config go.d/hddtemp.conf
```
#### Options

The following options can be defined globally: update_every, autodetection_retry.


<details><summary>Config options</summary>

| Name | Description | Default | Required |
|:----|:-----------|:-------|:--------:|
| update_every | Data collection frequency. | 1 | no |
| autodetection_retry | Recheck interval in seconds. Zero means no recheck will be scheduled. | 0 | no |
| address | The IP address and port where the hddtemp daemon listens for connections. | 127.0.0.1:7634 | yes |
| timeout | Connection, read, and write timeout duration in seconds. The timeout includes name resolution. | 1 | no |

## Troubleshooting

### Debug Mode

To troubleshoot issues with the `hddtemp` collector, run the `go.d.plugin` with the debug option enabled. The output
should give you clues as to why the collector isn't working.

- Navigate to the `plugins.d` directory, usually at `/usr/libexec/netdata/plugins.d/`. If that's not the case on
  your system, open `netdata.conf` and look for the `plugins` setting under `[directories]`.

  ```bash
  cd /usr/libexec/netdata/plugins.d/
  ```

- Switch to the `netdata` user.

  ```bash
  sudo -u netdata -s
  ```

- Run the `go.d.plugin` to debug the collector:

  ```bash
  ./go.d.plugin -d -m hddtemp
  ```
