-# Monitor disk (diskspace.plugin)
-
-This plugin monitors the disk space usage of mounted disks, under Linux. The plugin requires Netdata to have execute/search permissions on the mount point itself, as well as each component of the absolute path to the mount point.
-
-Two charts are available for every mount:
-
-- Disk Space Usage
-- Disk Files (inodes) Usage
-
-## configuration
-
-Simple patterns can be used to exclude mounts from showed statistics based on path or filesystem. By default read-only mounts are not displayed. To display them `yes` should be set for a chart instead of `auto`.
-
-By default, Netdata will enable monitoring metrics only when they are not zero. If they are constantly zero they are ignored. Metrics that will start having values, after Netdata is started, will be detected and charts will be automatically added to the dashboard (a refresh of the dashboard is needed for them to appear though).
-
-Netdata will try to detect mounts that are duplicates (i.e. from the same device), or binds, and will not display charts for them, as the device is usually already monitored.
-
-To configure this plugin, you need to edit the configuration file `netdata.conf`. You can do so by using the `edit config` script.
-
-> ### Info
->
-> To edit configuration files in a safe way, we provide the [`edit config` script](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md#use-edit-config-to-edit-configuration-files) located in your [Netdata config directory](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md#the-netdata-config-directory) (typically is `/etc/netdata`) that creates the proper file and opens it in an editor automatically.
-> It is recommended to use this way for configuring Netdata.
->
-> Please also note that after most configuration changes you will need to [restart the Agent](https://github.com/netdata/netdata/blob/master/docs/configure/start-stop-restart.md) for the changes to take effect.
-
-```bash
-cd /etc/netdata # Replace this path with your Netdata config directory, if different
-sudo ./edit-config netdata.conf
-```
-
-You can enable the effect of each line by uncommenting it.
-
-You can set `yes` for a chart instead of `auto` to enable it permanently. You can also set the `enable zero metrics` option to `yes` in the `[global]` section which enables charts with zero metrics for all internal Netdata plugins.
-
-```conf
-[plugin:proc:diskspace]
- # remove charts of unmounted disks = yes
- # update every = 1
- # check for new mount points every = 15
- # exclude space metrics on paths = /proc/* /sys/* /var/run/user/* /run/user/* /snap/* /var/lib/docker/*
- # exclude space metrics on filesystems = *gvfs *gluster* *s3fs *ipfs *davfs2 *httpfs *sshfs *gdfs *moosefs fusectl autofs
- # space usage for all disks = auto
- # inodes usage for all disks = auto
-```
-
-Charts can be enabled/disabled for every mount separately, just look for the name of the mount after `[plugin:proc:diskspace:`.
-
-```conf
-[plugin:proc:diskspace:/]
- # space usage = auto
- # inodes usage = auto
-```

+
+## 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:
+
+| Label | Description |
+|:-----------|:----------------|
+| mount_point | Path used to mount a filesystem |
+| filesystem | The filesystem used to format a partition. |
+| mount_root | Root directory where mount points are present. |
+
+Metrics:
+
+| Metric | Dimensions | Unit |
+|:------|:----------|:----|
+| disk.space | avail, used, reserved_for_root | GiB |
+| disk.inodes | avail, used, reserved_for_root | inodes |
+
+
+
+## Alerts
+
+
+The following alerts are available:
+
+| Alert name | On metric | Description |
+|:------------|:----------|:------------|
+| [ disk_space_usage ](https://github.com/netdata/netdata/blob/master/health/health.d/disks.conf) | disk.space | disk ${label:mount_point} space utilization |
+| [ disk_inode_usage ](https://github.com/netdata/netdata/blob/master/health/health.d/disks.conf) | disk.inodes | disk ${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:
+
+```ini
+[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](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md#the-netdata-config-directory).
+
+```bash
+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]`
+
+<details><summary>Config options</summary>
+
+| Name | Description | Default | Required |
+|:----|:-----------|:-------|:--------:|
+| update every | Data collection frequency. | 1 | False |
+| remove charts of unmounted disks | Remove chart when a device is unmounted on host. | yes | False |
+| check for new mount points every | Parse proc files frequency. | 15 | False |
+| exclude space metrics on paths | Do not show metrics (charts) for listed paths. This option accepts netdata simple pattern. | /proc/* /sys/* /var/run/user/* /run/user/* /snap/* /var/lib/docker/* | False |
+| exclude space metrics on filesystems | Do not show metrics (charts) for listed filesystems. This option accepts netdata simple pattern. | *gvfs *gluster* *s3fs *ipfs *davfs2 *httpfs *sshfs *gdfs *moosefs fusectl autofs | False |
+| exclude inode metrics on filesystems | Do not show metrics (charts) for listed filesystems. This option accepts netdata simple pattern. | msdosfs msdos vfat overlayfs aufs* *unionfs | False |
+| space usage for all disks | Define if plugin will show metrics for space usage. When value is set to `auto` plugin will try to access information to display if filesystem or path was not discarded with previous option. | auto | False |
+| inodes usage for all disks | Define if plugin will show metrics for inode usage. When value is set to `auto` plugin will try to access information to display if filesystem or path was not discarded with previous option. | auto | False |
