NAME

       nvme-pred-lat-event-agg-log - Send Predictable Latency Event Aggregate Log Page request,
       returns result and log

SYNOPSIS

       nvme pred-lat-event-agg-log <device> [--log-entries=<log_entries> | -e <log_entries>]
                               [--rae | -r] [--raw-binary | -b]
                               [--output-format=<fmt> | -o <fmt>]

DESCRIPTION

       Retrieves the NVMe Predictable Latency Event Aggregate Log Page from an NVMe device and
       provides the returned structure.

       The <device> parameter is mandatory and may be either the NVMe character device (ex:
       /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).

       On success, the returned Predictable Latency Event Aggregate Log Page 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.

OPTIONS

       -e <log_entries>, --log-entries=<log_entries>
           Retrieve the Predictable Latency Event Aggregate Log pending entries. This argument is
           mandatory and its success may depend on the device’s statistics to provide this log
           For More details see NVM Express 1.4 Spec. Section 5.14.1.11. The maximum number of
           log entries supported is 2044 for the device.

       -r, --rae
           Retain an Asynchronous Event.

       -b, --raw-binary
           Print the raw Predictable Latency Event Aggregate log buffer to stdout.

       -o <format>, --output-format=<format>
           Set the reporting format to normal, json, or binary. Only one output format can be
           used at a time.

EXAMPLES

       •   Print the Predictable Latency Event Aggregate Log page in a human readable format:

               # nvme pred-lat-event-agg-log /dev/nvme0

       •   Print the raw Predictable Latency Event Aggregate log to a file:

               # nvme pred-lat-event-agg-log /dev/nvme0 --raw-binary > pred_lat_agg_log.raw

           It is probably a bad idea to not redirect stdout when using this mode.
