The plugin calls `sysctl` function to collect necessary data. This collector is supported on all platforms. This collector supports collecting metrics from multiple instances of this integration, including remote instances. This integration doesn't support auto-detection. 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. These metrics give a general vision about I/O events on disks. This scope has no labels. Metrics: | Metric | Dimensions | Unit | |:|:-|:-| | system.io | io, out | KiB/s | This scope has no labels. Metrics: | Metric | Dimensions | Unit | |:|:-|:-| | disk.io | reads, writes, frees | KiB/s | | disk.ops | reads, writes, other, frees | operations/s | | disk.qops | operations | operations | | disk.util | utilization | % of time working | | disk.iotime | reads, writes, other, frees | milliseconds/s | | disk.await | reads, writes, other, frees | milliseconds/operation | | disk.avgsz | reads, writes, frees | KiB/operation | | disk.svctm | svctm | milliseconds/operation | The following alerts are available: | Alert name | On metric | Description | |:|:-|:| | | disk.util | average percentage of time ${label:device} disk was busy over the last 10 minutes | No action required. The configuration file name for this integration is `netdata.conf`. Configuration for this specific integration is located in the `[plugin:freebsd:kern.devstat]` section within that

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 ``` <details><summary>Config options</summary> | Name | Description | Default | Required | |:-|:--|:-|:--:| | enable new disks detected at runtime | Enable or disable possibility to detect new disks. | auto | no | | performance metrics for pass devices | Enable or disable metrics for disks with type `PASS`. | auto | no | | total bandwidth for all disks | Enable or disable total bandwidth metric for all disks. | yes | no | | bandwidth for all disks | Enable or disable bandwidth for all disks metric. | auto | no | | operations for all disks | Enable or disable operations for all disks metric. | auto | no | | queued operations for all disks | Enable or disable queued operations for all disks metric. | auto | no | | utilization percentage for all disks | Enable or disable utilization percentage for all disks metric. | auto | no | | i/o time for all disks | Enable or disable I/O time for all disks metric. | auto | no | | average completed i/o time for all disks | Enable or disable average completed I/O time for all disks metric. | auto | no | | average completed i/o bandwidth for all disks | Enable or disable average completed I/O bandwidth for all disks metric. | auto | no | | average service time for all disks | Enable or disable average service time for all disks metric. | auto | no | | disable by default disks matching | Do not create charts for disks listed. | | no | </details> There are no configuration examples.
