# DiskIO Input Plugin
The diskio input plugin gathers metrics about disk traffic and timing.
### Configuration:
```
# Read metrics about disk IO by device
[[inputs.diskio]]
## By default, telegraf will gather stats for all devices including
## disk partitions.
## Setting devices will restrict the stats to the specified devices.
# devices = ["sda", "sdb"]
## Uncomment the following line if you need disk serial numbers.
# skip_serial_number = false
```
Data collection is based on github.com/shirou/gopsutil. This package handles platform dependencies and converts all timing information to milliseconds.
### Measurements & Fields:
- diskio
- reads (integer, counter)
- writes (integer, counter)
- read_bytes (integer, bytes)
- write_bytes (integer, bytes)
- read_time (integer, milliseconds)
- write_time (integer, milliseconds)
- io_time (integer, milliseconds)
- iops_in_progress (integer, counter) (since #2037, not yet in STABLE)
### Tags:
- All measurements have the following tags:
- name (device name)
- If configured to use serial numbers (default: disabled):
- serial (device serial number)
### Example Output:
```
% telegraf -config ~/.telegraf/telegraf.conf -input-filter diskio -test
