# Storage devices monitoring with Netdata Monitors `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 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 Edit the `python.d/smartd_log.conf` configuration file using `edit-config` from the Netdata [config directory](/docs/configure/nodes.md), which is typically at `/etc/netdata`. ```bash cd /etc/netdata # Replace this path with your Netdata config directory, if different sudo ./edit-config python.d/smartd_log.conf ``` ```yaml local: log_path : '/var/log/smartd/' ``` If no configuration is given, module will attempt to read log files in `/var/log/smartd/` directory. --- [](<>)
