NVME-SOLIDIGM-LATE(1) NVMe Manual NVME-SOLIDIGM-LATE(1) NAME nvme-solidigm-latency-tracking-log - Enable/Retrieve Latency tracking Log SYNOPSIS nvme solidigm latency-tracking-log <device> [--enable | -e] [--disable | -d] [--read | -r] [--write | -w] [--type <value> | -t <value>] [--output-format=<fmt> | -o <fmt>] DESCRIPTION Enables, disables, or retrieves the Solidigm latency tracking log for the given NVMe device. This log provides detailed information about I/O latencies. The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1). OPTIONS -e, --enable Enable latency tracking before retrieving the log. -d, --disable Disable latency tracking after retrieving the log. -r, --read Retrieve read latency statistics (default if neither --read nor --write is specified). -w, --write Retrieve write latency statistics. -t <value>, --type <value> Specify the log type to retrieve. Valid values depend on the device's capabilities. -o <fmt>, --output-format=<fmt> Set the reporting format to normal, json, or binary. Only one output format can be used at a time. EXAMPLES • Enable latency tracking and retrieve the read latency log: # nvme solidigm latency-tracking-log /dev/nvme0 --enable --read • Retrieve the write latency log in JSON format: # nvme solidigm latency-tracking-log /dev/nvme0 --write -o json • Disable latency tracking after retrieving the log: # nvme solidigm latency-tracking-log /dev/nvme0 --disable • Specify a log type when retrieving latency statistics: # nvme solidigm latency-tracking-log /dev/nvme0 --type 1 --read NVME Part of the nvme-user suite NVMe 10/31/2024 NVME-SOLIDIGM-LATE(1)
