Usage Guidelines
The generated log files are in the current directory. The directory structure is as follows:
.
├── es3000v3_log
│ └── 20160709
│ ├── nvme0_coredump_050254.log
│ ├── nvme0_fw_050254.log
│ ├── nvme0_fw_050254.tmp
│ ├── nvme0_key_050254.log

The .tmp files contain original log data. The .log files are exported logs.
