# Disk Input Plugin
|
||
|
|
|
||
|
|
The disk input plugin gathers metrics about disk usage.
|
||
|
|
|
||
|
|
Note that `used_percent` is calculated by doing `used / (used + free)`, _not_
|
||
|
|
`used / total`, which is how the unix `df` command does it. See
|
||
|
|
https://en.wikipedia.org/wiki/Df_(Unix) for more details.
|
||
|
|
|
||
|
|
### Configuration:
|
||
|
|
|
||
|
|
```
|
||
|
|
# Read metrics about disk usage by mount point
|
||
|
|
[[inputs.disk]]
|
||
|
|
# By default, telegraf gather stats for all mountpoints.
|
||
|
|
# Setting mountpoints will restrict the stats to the specified mountpoints.
|
||
|
|
# mount_points = ["/"]
|
||
|
|
```
