smart.go
Smart.go is a pure Golang library to access disk low-level S.M.A.R.T. information. Smart.go tries to match functionality provided by smartctl but with golang API.
Currently this library support SATA, SCSI and NVMe drives. Different drive types provide different set of monitoring information and API reflects it.
Example
Here is an example of code that demonstrates the library usage.
<< ns.Lbaf[ns.Flbas&0xf].Ds fmt.Println("Namespace 1 utilization: ", ns.Nuse*lbaSize) sm, _ := dev.ReadSMART() fmt.Println("Temperature: ", sm.Temperature, "K") // PowerOnHours is reported as 128-bit value and represented by this library as an array of uint64 fmt.Println("Power-on hours: ", sm.PowerOnHours.Val[0]) fmt.Println("Power cycles: ", sm.PowerCycles.Val[0])">
// skip the error handling for more compact API example dev, _ := smart.OpenNVMe("/dev/nvme0n1") c, nss, _ := dev.Identify() fmt.Println("Model number: ", string(bytes.TrimSpace(c.ModelNumber[:]))) fmt.Println("Serial number: ", string(bytes.TrimSpace(c.SerialNumber[:]))) fmt.Println("Size: ", c.Tnvmcap.Val[0]) // namespace #1 ns := nss[0] lbaSize := uint64(1) << ns.Lbaf[ns.Flbas&0xf].Ds fmt.Println("Namespace 1 utilization: ", ns.Nuse*lbaSize) sm, _ := dev.ReadSMART() fmt.Println("Temperature: ", sm.Temperature, "K") // PowerOnHours is reported as 128-bit value and represented by this library as an array of uint64 fmt.Println("Power-on hours: ", sm.PowerOnHours.Val[0]) fmt.Println("Power cycles: ", sm.PowerCycles.Val[0])
The output looks like
Model number: SAMSUNG MZVLB512HBJQ-000L7
Serial number: S4ENNF0M741521
Size: 512110190592
Namespace 1 utilization: 387524902912
Temperature: 327 K
Power-on hours: 499
Power cycles: 1433
