# nvme-log-endurance-event-agg(1)

Send NVMe Endurance log page request, returns result and log

## NAME

nvme-log-endurance-event-agg - Send NVMe Endurance log page request, returns result and log

## SYNOPSIS

```
nvme [<global-options>] log endurance-event-agg <device>
                        [--log-entries=<log_entries> | -e <log_entries>]
                        [--rae | -r]
                        [--raw-binary | -b]
```

## DESCRIPTION

Retrieves the NVMe Endurance 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 endurance event agg 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, the raw buffer may be printed to stdout for another program to parse, or reported in json format.

## OPTIONS

- \-e \<log\_entries\>, --log-entries=\<log\_entries\>

  Retrieve the Endurance Group 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 5.14.1.15. The maximum number of log entries supported is 2044 for the device.

- \-r, --rae

  Retain an Asynchronous Event.

## GLOBAL OPTIONS

The following options are defined at the top-level nvme command and are available to this subcommand:

- \--dry-run

  Print the command that would be executed, but do not actually execute it.

- \--no-ioctl-probing

  Disable probing for 64-bit IOCTL support.

- \--no-retries

  Disable retry logic on transient errors.

- \-o \<fmt\>, --output-format=\<fmt\>

  Set the reporting format to *normal*, *tabular, 'json*, or *binary*. Only one output format may be used at a time.

- \--output-format-version=\<version\>

  Select the output format version. Version *1* uses the original field naming, while version *2* (default) provides more consistent and script-friendly field names. Other versions are rejected.

- \--quiet

  Suppress informational messages. Errors are still reported, and --quiet cancels any --verbose for the library log level.

- \--set-options=\<key=value\>\[,\<key=value\>...\]

  Set libnvme library options for this invocation. Supported keys are *force-4k*, *mi-probe-enabled*, *test-base-dir* and *test-sysfs-dir*.

- \--timeout=\<ms\>

  Set the timeout for the command in milliseconds. *infinite* or *-1* waits without a time limit (0xffffffff).

- \-v, --verbose

  Increase the level of detail in the output. May be specified multiple times to further increase verbosity.

These options can also be set as machine-wide defaults in [nvme-cli.conf(5)](/nvme-cli.conf/5.md). A command-line flag always overrides the file.

## EXAMPLES

• Print the Endurance log page in a human readable format:

```
# nvme log endurance-event-agg /dev/nvme0
```

• Print the raw Endurance log to a file:

```
# nvme log endurance-event-agg /dev/nvme0 --output=binary > endurance_event_agg_log.raw
```

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