Options

--events <string>

Specifies which event types for the specified information are reported. The following values are valid:

blocked

Access to the LIN was blocked waiting for a resource to be released by another operation. Class is other.

contended

A LIN is experiencing cross-node contention; it is being accessed simultaneously through multiple nodes. Class is other.

deadlocked

The attempt to lock the LIN resulted in deadlock. Class is other.

getattr

A file or directory attribute has been read. Class is namespace_read.

link

The LIN has been linked into the file system; the LIN associated with this event is the parent directory and not the linked LIN. Class is namespace_write.

lock

The LIN is locked. Class is other.

lookup

A name is looked up in a directory; the LIN for the directory searched is the one associated with the event. Class is namespace_read.

read

A read was performed. Class is read.

rename

A file or directory was renamed. The LIN associated with this event is the directory where the rename took place for either the source directory or the destination directory, if they differ. Class is namespace_write.

setattr

A file or directory attribute has been added, modified, or deleted. Class is namespace_write.

unlink

A file or directory has been unlinked from the file system, the LIN associated with this event is the parent directory of the removed item. Class is namespace_write.

write

A write was performed. Class is write.

-pathdepth <integer>

Reduces paths to the specified depth.

--maxpath <integer>

Specifies the maximum path length to look up in the file system.

--classes <string>

Specifies which classes for the specified information will be reported. The default setting is all classes. The following values are valid:

write

File and stream writing

read

File and stream reading

namespace_write

Renames; attribute setting; permission, time, and ACL writes

namespace_read

Attribute, stat, and ACL reads; lookup, directory reading

other

File-system information

--numeric

If text identifiers of local hosts, remote clients, or users are in the list of columns to display (the default setting is for them to be displayed), display the unresolved numeric equivalent of these columns.

{ --nodes | -n} <value>

Specifies which nodes to report statistics on. Multiple values can be specified in a comma-separated list—for example, --nodes 1,2. The default value is all. The following values are valid:

• all
• <int>

{--degraded | -d}

Sets the report to continue running if some nodes do not respond.

--nohumanize

Displays all data in base quantities, without dynamic conversion. If set, this option also disables the display of units within the data table.

{--interval | -I} <integer>

Reports data at the interval specified in seconds.

{--repeat | -r} <integer>

Specifies how many times to run the report before quitting.

NOTE:To set the report to run indefinitely, specify -1.

--limit <integer>

Displays only the specified number of entries after totaling and ordering.

--long

Displays all possible columns.

--totalby <column>

Aggregates results according to specified fields. The following values are valid:

• Node
• {Event | event_name}
• {Class | class_name}
• LIN
• Path

--output <column>

Specifies the columns to display. The following values are valid:

{Ops | operation_rate}

Displays the rate at which an operation has been performed. Displayed in operations per second.

Node

Displays the node on which the operation was performed.

{Event | event_name}

Displays the name of the event.

{ Class | class_name}

Displays the class of the operation.

LIN

Displays the LIN for the file or directory associated with the event.

Path

Displays the path associated with the event LIN.

--sort <column>

Specifies how rows are ordered. The following values are valid:

• {Ops | operation_rate}
• Node
• {Event | event_name}
• {Class | class_name}
• LIN
• Path

--format {table | json | csv | list | top}

Displays output in table, JavaScript Object Notation (JSON), comma-separated value (CSV), list format, or top-style display where data is continuously overwritten in a single table.

NOTE:If you specify--top without --repeat, the report runs indefinitely.

{--noheader | -a}

Displays data without column headings.

{ --no-footer | -z}

Displays data without footers.

{--verbose | -v}

Displays more detailed information.
