Disk space

Plugin: diskspace.plugin Module: diskspace.plugin

Overview

Monitor Disk space metrics for proficient storage management. Keep track of usage, free space, and error rates to prevent disk space issues.

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

The plugin reads data from /proc/self/mountinfo and /proc/diskstats file.

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 mount point

Labels:

LabelDescription
mount_pointPath used to mount a filesystem
filesystemThe filesystem used to format a partition.
mount_rootRoot directory where mount points are present.

Metrics:

MetricDimensionsUnit
disk.spaceavail, used, reserved_for_rootGiB
disk.inodesavail, used, reserved_for_rootinodes

Alerts

The following alerts are available:

Alert nameOn metricDescription
disk_space_usage disk.spacedisk ${label:mount_point} space utilization
disk_inode_usage disk.inodesdisk ${label:mount_point} inode utilization

Setup

Prerequisites

No action required.

Configuration

File

The configuration file name for this integration is netdata.conf. Configuration for this specific integration is located in the [plugin:proc:diskspace] section within that file.

The file format is a modified INI syntax. The general structure is:

[section1]
option1 = some value
option2 = some other value

[section2]
option3 = some third value

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 netdata.conf

Options

You can also specify per mount point [plugin:proc:diskspace:mountpoint]
