Use the lscounters command to list available performance counters.

Syntax

Parameters and arguments

-user user_name: Specifies an IBM Spectrum Control user ID.
-pwd password: Specifies the password for the IBM Spectrum Control user ID.
-url url: Specifies the Device server. The format of the URL is system:port_number, where system represents either the host name or IP address, and port_number represents the IBM Spectrum Control Device server port.
-fabric WWN: Specifies the fabric. The WWN variable is the worldwide name (WWN).
-subsys subsystem: Specifies the storage subsystem. The subsystem variable is the GUID of the storage subsystem. You can use the lsdev command to return information, including the GUID, for all storage subsystems that are discovered by IBM Spectrum Control.
-ctype comp_type: Specifies that the output is to include only components of the specified type. For more information about the comp_type variable, see the lstype command.
-level sample | hourly | daily: Specifies the level for which the performance counters are to be summarized. You can specify a sample summary, an hourly summary, or a daily summary.
-fs character: Specifies the 7-bit character that separates the information in the output. If you omit this parameter, the information is separated by blank spaces.
-header: Suppresses the column headings in the output. If you omit this parameter, the column headings are included.
-help | -h | -?: Lists help information for the command.
-qs character: Specifies the 7-bit character that surrounds character strings and date stamps in the output. If you omit this parameter, character strings and date stamps are enclosed by double quotation marks (").
-silent: Suppresses all output for the command. If you omit this parameter, output is included.

Example: Listing performance counters

The following command generates a list of performance counters for volumes on the specified storage subsystem:

tpctool> lscounters -user me -pwd mypass -url myhost:myport 
-subsys 2105.22232+0 -ctype vol -level sample

The following output is returned.
