# Telegraf S.M.A.R.T. plugin # S.M.A.R.T. Input Plugin
Get metrics using the command line utility `smartctl` for S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) storage devices. SMART is a monitoring system included in computer hard disk drives (HDDs) and solid-state drives (SSDs)[1] that detects and reports on various indicators of drive reliability, with the intent of enabling the anticipation of hardware failures.

## Measurements ### Configuration:
- smart_device:
* Tags:
- `capacity`
- `device`
- `device_model`
- `enabled`
- `health`
- `serial_no`
- `wwn`
* Fields:
- `exit_status`
- `health_ok`
- `read_error_rate`
- `seek_error`

- `serial_no`
- `wwn`
* Fields:
- `exit_status`
- `raw_value`
- `threshold`
- `value`
- `worst`
### Flags
The interpretation of the tag `flags` is:
- *K* auto-keep
- *C* event count
- *R* error rate
- *S* speed/performance
- *O* updated online
- *P* prefailure warning
### Exit Status
The `exit_status` field captures the exit status of the smartctl command which
is defined by a bitmask. For the interpretation of the bitmask see the man page for
smartctl.
### Device Names
Device names, e.g., `/dev/sda`, are *not persistent*, and may be
subject to change across reboots or system changes. Instead, you can the
*World Wide Name* (WWN) or serial number to identify devices. On Linux block
devices can be referenced by the WWN in the following location:
`/dev/disk/by-id/`.
