Options

--classes <class>

Specifies which operation classes to report statistics on. The following values are valid:

other

File-system information. Multiple values can be specified in a comma-separated list.

write

File and stream writing

read

File and stream reading

create

File link node stream and directory creation

delete

File link node stream and directory deletion

namespace_read

Attribute stat and ACL reading; lookup directory reading

namespace_write

Renames; attribute setting; permission time and ACL writes

file_state

Open, close; locking: acquire, release, break, check; notification

session_state

Negotiation inquiry or manipulation of protocol connection or session state

--protocols <value>

Specifies which protocols to report statistics on. Multiple values can be specified in a comma-separated list, for example --protocols http,papi. The following values are valid:

• all
• external
• ftp
• hdfs
• http
• internal
• irp
• jobd
• lsass_in
• lsass_out
• nfs3
• nfs4
• nlm
• papi
• s3
• siq
• smb1
• smb2

--operations <operation>

Specifies the operations on which statistics are reported. To view a list of valid values, run the isi statistics list operations command. Multiple values can be specified in a comma-separated list.

--zero

Shows table entries with no values.

{--nodes | -n} <node>

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}

Causes 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 in the data table.

{--interval | -i} <float>

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 | -l}<integer>

Limits the number of statistics to display.

--long

Displays all possible columns.

--totalby <column>

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

• Node
• {Proto | protocol}
• Class
• {Op | operation}

--output <column>

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

{timestamp | time}

Displays the time at which the isi statistics tool last gathered data. Displayed in POSIX time (number of seconds elapsed since January 1, 1970).

Specify <time-and-date> in the following format:

<YYYY>-<MM>-<DD>[T<hh>:<mm>[:<ss>]]

Specify <time> as one of the following values.

Y

Specifies years

M

Specifies months

W

Specifies weeks

D

Specifies days

h

Specifies hours

s

Specifies seconds

{NumOps | operation_count}

{InMax | in_max}

Displays the maximum input (received) bytes for an operation.

{InMin | in_min}

Displays the minimum input (received) bytes for an operation.

In

Displays the rate of input for an operation since the last time isi statistics collected the data. Displayed in bytes per second.

{InAvg | in_avg}

Displays the average input (received) bytes for an operation.

{InStdDev | in_standard_dev}

Displays the standard deviation of the input (received) bytes for an operation. Displayed in bytes.

{OutMax | out_max}

Displays the maximum output (sent) bytes for an operation.

{OutMin | out_min}

Displays the minimum ouput (sent) bytes for an operation.

Out

{OutAvg | out_avg}

Displays the average ouput (sent) bytes for an operation.

{OutStdDev | out_standard_dev}

Displays the standard deviation of the output (sent) bytes for an operation. Displayed in bytes.

{TimeMax | time_max}

{TimeAvg | time_avg}

Displays the average elapsed time taken to complete an operation. Displayed in microseconds.

{TimeStdDev | time_standard_dev}

Displays the elapsed time taken to complete an operation as a standard deviation from the mean elapsed time.

Node

Displays the node on which the operation was performed.

{Proto | protocol}
