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:

LabelDescription
disk_idDisk identifier. It is derived from the device path (e.g. sda or ata-HUP722020APA330_BFJ0WS3F)
modelDisk model

Metrics:

MetricDimensionsUnit
hddtemp.disk_temperaturetemperatureCelsius
hddtemp.disk_temperature_sensor_statusok, err, na, unk, nos, slpstatus

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.

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.

Config options
NameDescriptionDefaultRequired
update_everyData collection frequency.1no
autodetection_retryRecheck interval in seconds. Zero means no recheck will be scheduled.0no
addressThe IP address and port where the hddtemp daemon listens for connections.127.0.0.1:7634yes
timeoutConnection, read, and write timeout duration in seconds. The timeout includes name resolution.1no

Troubleshooting

Debug Mode

Important: Debug mode is not supported for data collection jobs created via the UI using the Dyncfg feature.

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].

    cd /usr/libexec/netdata/plugins.d/
  • Switch to the netdata user.

    sudo -u netdata -s
  • Run the go.d.plugin to debug the collector:

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

Getting Logs

If you're encountering problems with the hddtemp collector, follow these steps to retrieve logs and identify potential issues:

  • Run the command specific to your system (systemd, non-systemd, or Docker container).
  • Examine the output for any warnings or error messages that might indicate issues. These messages should provide clues about the root cause of the problem.

System with systemd

Use the following command to view logs generated since the last Netdata service restart:

journalctl _SYSTEMD_INVOCATION_ID="$(systemctl show --value --property=InvocationID netdata)" --namespace=netdata --grep hddtemp

System without systemd

Locate the collector log file, typically at /var/log/netdata/collector.log, and use grep to filter for collector's name:

grep hddtemp /var/log/netdata/collector.log

Note: This method shows logs from all restarts. Focus on the latest entries for troubleshooting current issues.

Docker Container

If your Netdata runs in a Docker container named "netdata" (replace if different), use this command:

docker logs netdata 2>&1 | grep hddtemp
