+.SH "DESCRIPTION"
+.sp
+Retrieves the NVMe Predictable latency per NVM set log page from an NVMe device and provides the returned structure\&.
+.sp
+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
+.sp
+On success, the returned Predictable latency per NVM set log structure may be returned in one of several ways depending on the option flags; the structure may parsed by the program and printed in a readable format or the raw buffer may be printed to stdout for another program to parse\&.
+.SH "OPTIONS"
+.PP
+\-i <nvmset_id>, \-\-nvmset\-id=<nvmset_id>
+.RS 4
+Retrieve the Predictable latency per NVM set log for the given nvmset id\&. This argument is mandatory and its success may depend on the device\(cqs statistics to provide this log For More details see NVM Express 1\&.4 Spec\&. Section 5\&.14\&.1\&.10\&. The default nvmset id to use is 1 for the device\&.
