# smartd_log

Module monitor `smartd` log files to collect HDD/SSD S.M.A.R.T attributes.

**Requirements:**

-   `smartmontools`

It produces following charts for SCSI devices:

1.  **Read Error Corrected**

2.  **Read Error Uncorrected**

3.  **Write Error Corrected**

4.  **Write Error Uncorrected**

5.  **Verify Error Corrected**

6.  **Verify Error Uncorrected**

7.  **Temperature**

For ATA devices:

1.  **Read Error Rate**

2.  **Seek Error Rate**

3.  **Soft Read Error Rate**

4.  **Write Error Rate**

5.  **SATA Interface Downshift**

6.  **UDMA CRC Error Count**

7.  **Throughput Performance**

8.  **Seek Time Performance**

9.  **Start/Stop Count**

10. **Power-On Hours Count**

11. **Power Cycle Count**

12. **Unexpected Power Loss**

13. **Spin-Up Time**

14. **Spin-up Retries**

15. **Calibration Retries**

16. **Temperature**

17. **Reallocated Sectors Count**

18. **Reserved Block Count**

19. **Program Fail Count**

20. **Erase Fail Count**

21. **Wear Leveller Worst Case Erase Count**

22. **Unused Reserved NAND Blocks**

23. **Reallocation Event Count**

24. **Current Pending Sector Count**

25. **Offline Uncorrectable Sector Count**

26. **Percent Lifetime Used**

## prerequisite

`smartd` must be running with `-A` option to write smartd attribute information to files.

For this you need to set `smartd_opts` (or `SMARTD_ARGS`, check _smartd.service_ content) in `/etc/default/smartmontools`:

```
# dump smartd attrs info every 600 seconds
smartd_opts="-A /var/log/smartd/ -i 600"
```

You may need to create the smartd directory before smartd will write to it: 

```sh
mkdir -p /var/log/smartd
```

Otherwise, all the smartd `.csv` files may get written to `/var/lib/smartmontools` (default location). See also <https://linux.die.net/man/8/smartd> for more info on the `-A --attributelog=PREFIX` command.

`smartd` appends logs at every run. It's strongly recommended to use `logrotate` for smartd files.

## configuration

```yaml
local:
  log_path : '/var/log/smartd/'
```

If no configuration is given, module will attempt to read log files in `/var/log/smartd/` directory.
