HDD temperature

Plugin: python.d.plugin Module: hddtemp

Overview

This collector monitors disk temperatures.

It uses the hddtemp daemon to gather the metrics.

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 HDD temperature instance

These metrics refer to the entire monitored application.

This scope has no labels.

Metrics:

Metric	Dimensions	Unit
hddtemp.temperatures	a dimension per disk	Celsius

Alerts

There are no alerts configured by default for this integration.

Setup

Prerequisites

Run hddtemp in daemon mode

You can execute hddtemp in TCP/IP daemon mode by using the -d argument.

So running hddtemp -d would run the daemon, by default on port 7634.

Configuration

File

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

Options

There are 2 sections:

• Global variables
• One or more JOBS that can define multiple different instances to monitor.

The following options can be defined globally: priority, penalty, autodetection_retry, update_every, but can also be defined per JOB to override the global values.

Additionally, the following collapsed table contains all the options that can be configured inside a JOB definition.

Every configuration JOB starts with a job_name value which will appear in the dashboard, unless a name parameter is specified.

By default this collector will try to autodetect disks (autodetection works only for disk which names start with "sd"). However this can be overridden by setting the option disks to an array of desired disks.

Config options

Name	Description	Default	Required
update_every	Sets the default data collection frequency.	1	no
priority	Controls the order of charts at the netdata dashboard.	60000	no
autodetection_retry	Sets the job re-check interval in seconds.	0	no
penalty	Indicates whether to apply penalty to update_every in case of failures.	yes	no
name	Job name. This value will overwrite the job_name value. JOBS with the same name are mutually exclusive. Only one of them will be allowed running at any time. This allows autodetection to try several alternatives and pick the one that works.	local	no
devices	Array of desired disks to detect, in case their name doesn't start with sd.		no
host	The IP or HOSTNAME to connect to.	localhost	yes
port	The port to connect to.	7634	no

Examples

Basic

A basic example configuration.

localhost:
  name: 'local'
  host: '127.0.0.1'
  port: 7634

Custom disk names

An example defining the disk names to detect.

Config

localhost:
  name: 'local'
  host: '127.0.0.1'
  port: 7634
  devices:
    - customdisk1
    - customdisk2

Multi-instance

Note: When you define multiple jobs, their names must be unique.

Collecting metrics from local and remote instances.

Config

localhost:
  name: 'local'
  host: '127.0.0.1'
  port: 7634

remote_job:
  name : 'remote'
  host  : 'http://192.0.2.1:2812'

Troubleshooting

Debug Mode

To troubleshoot issues with the hddtemp collector, run the python.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 python.d.plugin to debug the collector:

  ./python.d.plugin hddtemp debug trace
