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. The plugin reads data from `/proc/self/mountinfo` and `/proc/diskstats file`. The default configuration for this integration does not impose any limits on data collection. The default configuration for this integration is not expected to impose a significant performance impact on the system. Metrics grouped by scope. The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels. 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, reservedforroot | GiB | | disk.inodes | avail, used, reservedforroot | inodes | The following alerts are available: | Alert name | On metric | Description | |:|:-|:| | | disk.space | disk ${label:mount_point} space utilization | | | disk.inodes | disk ${label:mount_point} inode utilization | No action required. 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 . ```bash cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata sudo ./edit-config netdata.conf ``` 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 | no | | remove charts of unmounted disks | Remove chart when a device is unmounted on host. | yes | no | | check for new mount points every | Parse proc files frequency. | 15 | no | | 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/ | no | | 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 | no | | 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 | no | | 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 | no | | 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 | no | </details> There are no configuration examples.
