Export Tool

The following table describes the terms used by Export Tool 2.

Before installing the Export Tool 2 software on the management client, verify that the management client meets the system requirements listed in the following table.

The following table shows the VSP E series estimated used memory size, drive size, and time required for each configuration when runing microcode version 93-06-21-xx or later with 33 or more target CUs and a sampling interval of 5 to 60 minutes (288 plots).

The following table shows the VSP E series estimated used memory size, drive size, and time required for each configuration when running microcode version 93-06-21-xx or later with 32 or less target CUs and a sampling interval of 1 to 15 minutes (1440 plots).

The show interval command displays the sampling interval (how often, in minutes, monitoring data is collected).

show interval -ip <IP address> -login <User name> <Password> -proxy <IP address> <Port number> <User name> <Password>

• -ip <IP Address>

  Specifies the IP address of GUM (IPv4 or IPv6 format) or host name.

• -login <user name> <password>

  Specifies the user ID and password of the Export Tool 2 user. If this option is omitted, you will be prompted to enter your user ID and password.

• -proxy <IP address or host name> <port number> <user name> <password>

  If the management client is connected to the storage system through a proxy server, this option specifies the proxy information (IP address [IPv4 or IPv6 format] or host name, port number, user name and password). If <user name> and <password> are omitted here, but <user name> and <password> are specified for the -login parameter, the proxy is used without authentication. If <user name> and <password> are omitted and the -login parameter is omitted, you are prompted to enter the user ID and password for the proxy server.

Interval : ＜Value＞ min

Displays the sampling interval obtained from the storage system.

show interval -ip 192.168.0.100 -login User Pass
Interval : 50 min
show interval command success

The set interval command sets the sampling interval (in minutes) at which monitoring data is collected.

The results of this command differ depending on the storage system model and microcode version as follows:

• VSP E series with DKCMAIN microcode version 93-06-21 or later

  After you change the sampling interval, the accumulated performance information is discarded, and then the performance information collection starts using the new sampling interval.

  The number of plots (areas in which performance information is accumulated) differs depending on the combination of the number of Control Units (CUs) for which performance information is collected (target CUs) and the value of the sampling interval.

  To check the number of target CUs, use the show cu command. To specify the target CUs, use the add cu and remove cu commands.

  • If the number of the target CUs is 32 or fewer, specify an integer from 1 to 15 for the sampling interval. The number of plots will be 1440.
  • If the number of the target CUs is 33 or more, specify a value for the sampling interval that is a multiple of 5 in the range from 5 to 60. The number of plots will be 288.
• VSP E series with DKCMAIN microcode version earlier than 93-06-21 and storage system models other than VSP E series

  After you change the sampling interval, the accumulated performance information is not discarded. Also, the sampling interval for the plots in which performance information was accumulated before the setting change does not change. The number of plots does not differ depending on the combination of the number of target CUs and the set value of the sampling interval.

  Specify a value that is a multiple of 5 in the range from 5 to 60. The number of plots is 288.

set interval -ip <IP address> -login <User name> <Password> -proxy <IP 
address> <Port number> <User name> <Password> -interval <Sampling interval> -q

• -ip <IP Address>

  Specifies the IP address of GUM (IPv4 or IPv6 format) or host name.

• -login <user name> <password>

  Specifies the user ID and password of the Export Tool 2 user. If this option is omitted, you are prompted to enter your user ID and password.

• -proxy <IP address or host name> <port number> <user name> <password>

  If the management client is connected to the storage system through a proxy server, this option specifies the proxy information (IP address [IPv4 or IPv6 format] or host name, port number, user name and password). If <user name> and <password> are omitted here, but <user name> and <password> are specified for the -login parameter, the proxy is used without authentication. If <user name> and <password> are omitted and the -login parameter is omitted, you are prompted to enter the user ID and password for the proxy server.

  Specifies the sampling interval (in minutes). You must specify this parameter.

  • VSP E series with DKCMAIN microcode version 93-06-21 or later:
    • If the number of the target CUs is 32 or fewer, specify an integer from 1 to 15 (unit: minute).
    • If the number of the target CUs is 33 or more, specify a value that is a multiple of 5 in the range from 5 to 60 (unit: minute).
  • VSP E series with microcode version earlier than 93-06-21, and storage system models other than VSP E series:

    Specify a value that is a multiple of 5 in the range from 5 to 60 (unit: minute).

• -q

  Specifies to run the command without displaying a message that prompts you as to whether to discard the accumulated data and continue the processing. If you use this parameter, the accumulated data is automatically deleted. This parameter is only available for VSP E series running DKCMAIN microcode version 93-06-21 or later.

set interval -ip 192.168.0.100 -login User Pass -interval 50
Interval: 50 min
set interval command success

The show range command displays the list of accumulated monitoring data (list of date and time that indicate the retention period). You can use the performance metrics export function (export data command) to output performance information during this period of time.

show range -ip <IP address> -login <User name> <Password> -proxy <IP

Displays the number of CUs for which performance information is collected.

show cu -ip 192.168.0.100 -login User Pass
CUs  : 00,01,0F
show cu command success

The add cu command adds CUs for which performance information is collected (target CUs).

This command is available for VSP E series with a DKCMAIN microcode version of 93-06-21 or later.

Performance information collection starts for the newly added target CUs when the accumulated performance information is discarded.

add cu -ip <IP address> -login <User name> <Password> -proxy <IP 
address> <Port number> <User name> <Password> -cu <CU number> -q

• -ip <IP Address>

  Specifies the IP address of GUM (IPv4 or IPv6 format) or host name.

  If the management client is connected to the storage system through a proxy server, this option specifies the proxy information (IP address [IPv4 or IPv6 format] or host name, port number, user name and password). If <user name> and <password> are omitted here, but <user name> and <password> are specified for the -login parameter, the proxy is used without authentication. If <user name> and <password> are omitted and the -login parameter is omitted, you are prompted to enter the user ID and password for the proxy server.

• -cu <control unit number>

  Specifies the CU numbers that you want to add for which to collect performance information (in two-digit Hexadecimal numbers).

  When adding multiple CUs, use commas to separate them. You can also specify a range of CU numbers by delimiting the start and end numbers with a colon (:) (for example, “00:09” for the range from 00 to 09). You can also mix both formats (for example, “00,02,04:09”).

  The number of CU numbers that you can set differs depending on the sampling interval as described in set interval.

• -q

  Specifies to run the command without displaying a message that prompts you as to whether to discard the accumulated data and continue the processing. If you use this parameter, the accumulated data is automatically deleted.

add cu -ip 192.168.0.100 -login User Pass -cu 00,01,05:0A -q
add cu command success

The remove cu command removes CUs for which performance information is collected (target CUs).

This command is available for VSP E series with a DKCMAIN microcode version of 93-06-21 or later.

Performance information collection starts for the reduced set of CUs when the accumulated performance information is discarded.

If <user name> and <password> are omitted here, but <user name> and <password> are specified for the -login parameter, the proxy is used without authentication. If <user name> and <password> are omitted and the -login parameter is omitted, you are prompted to enter the user ID and password for the proxy server.

• -cu <control unit number>

  Specifies the CU numbers that you want to remove for which performance information is collected (in two-digit Hexadecimal numbers).

  When removing multiple CUs, use commas to separate them. You can also specify a range of CU numbers by delimiting the start and end numbers with a colon (:) (for example, “00:09” for the range from 00 to 09). You can also mix both formats (for example, “00,02,04:09”).

  The number of CU numbers that you can set differs depending on the sampling interval as described in set interval.

remove cu command success

The export data command exports accumulated performance metrics data to an (uncompressed) CSV file or a compressed ZIP file. You can export performance metrics information for any period of time that is included in the available timeframe. You can determine the time period for which data is accumulated by using the show range command.

The export data command outputs two types of files:

• CSV file for performance information
• CSV file for meta information (export_metadata.csv)

When an error occurs when running the export data command and the command is terminated, or when the command is interrupted by pressing Ctrl+c, files that were already output are not deleted.

export data -ip <IP address> -login <User name> <Password> -proxy <IP 
address> <Port number> <User name> <Password> -outpath <Output directory> -range 
<Range of accumulated data> -group <Group name> -option <Content of option>

• -ip <IP Address>

  Specifies the IP address of GUM (IPv4 or IPv6 format) or host name.

• -login <user name> <password>

  Specifies the user ID and password. If this option is omitted, you are prompted to enter your user ID and password.

• -proxy <IP address or host name> <port number> <user name> <password>

  If the management client is connected to the storage system through a proxy server, this option specifies the proxy information (IP address [IPv4 or IPv6 format] or host name, port number, user name and password). If <user name> and <password> are omitted here, but <user name> and <password> are specified for the -login parameter, the proxy is used without authentication. If <user name> and <password> are omitted and the -login parameter is omitted, you are prompted to enter the user ID and password for the proxy server.

• -outpath

  This option defines the output path of the files to export.

  A maximum of 150 characters can be used when specifying a full path.

  When specifying a relative path, consider the number of characters in a full path.

  When this option is omitted, the files are output to the monitor2\out directory.

  • Relative paths are supported.
  • Output to a network drive is not supported.
  • To include a space in a path, enclose it in double quotation marks ("" "").
  • To specify "\", specify "\\"）
  • If the specified directory does not exist, the directory is automatically created.

  This parameter is optional.

• -range

  Format: YYYYMMDDHHMM：YYYYMMDDHHMM

  This parameter defines the range of accumulated data you want to export (specifies date and time).

  All data that was accumulated in the specified range (date and time) is output.

  When this parameter is not specified, all data accumulated in the storage system is exported (up to 1440 plots).

  Because performance values are obtained from differences in accumulated data, the output performance values are reduced by 1 plot. (Time at the head is not output.)

  This parameter is optional.

• -group

  This parameter defines the performance metrics group name of the accumulated data you want to export.

  Specify one of the following performance metrics group names for the accumulated data you want to export:

  • MP
  • Cache
  • ParityGroup
  • LDEV
  • LU
    NoteThe same value is output to all LUs mapped to the LDEV. These files do not contain the monitoring data for a volume that does not accept I/O from the host, such as a pool volume. Performance monitoring data cannot be collected for a LU with an NVMe connection.
  • Port
  • PortError
  • LoginWWN
  • BackendPort
  • TrueCopy
  • UR

  You can specify group names in any order. To specify multiple groups, use a space to separate the group names (for example, MP Cache ParityGroup). When this parameter is not specified, accumulated data for all groups is exported.

• -option

  This parameter specifies the option to export data.

  You can specify one or more of the following options in any order:

  • Whether to delete a file in the save directory.

    ask: Ask the user whether to delete a file or subdirectory (in the save directory) that has the same name as the output file.

    clear: Delete both CSV and ZIP files (in the save directory) that have the same name as the output file.

    When this parameter is not specified, the process is the same as when you specify clear.

  • Whether to compress exported data

    compress: Compresses data (ZIP format)

    nocompress: Does not compress data

    When this parameter is not specified, the process is the same as when you specify compress.

  • Whether to list the resource ID per row or per column

    resourceid_on_row: Lists the resource ID in a row for the exported data

    When this option is specified, the ID of a resource (for example, port) is listed in a row in the exported data (CSV file for performance information). Therefore, each record contains performance information for each collection time and resource.

    Example CSV file output:

    "Date","Time","ID","Total_IOPS"
    "2017/07/10","18:00","CL1-A/1122334455667788<HOST_A>","10"
    "2017/07/10","18:00","CL1-A/1122334455667788<HOST_A>","10"

    resourceid_on_column: Lists the resource ID in a column for the exported data

    When this option is specified, the ID of a resource (for example, port) is output in multiple rows in the exported data (CSV file for performance information). Therefore, each record contains performance information for multiple resources collected at the same time.

    You can specify these options (resourceid_on_row and resourceid_on_column) for VSP E series with a DKCMAIN microcode version of 93-06-21 or later.

    When these options are not specified or your storage system does not support these options, the process is the same as when you specify resourceid_on_row.

    Example CSV file output:

    Total_IOPS.csv
    Serial Number : 610025(VSP E790)
    From : 2021/09/20 23:40
    To : 2021/09/20 23:45
    Sampling : 5
    "Date","Time","CL1-A/1122334455667788<HOST_A>","CL1-A/
    1122334455667788<HOST_B>"
    "2021/09/20","23:40","10","10"
    "2021/09/20","23:45","10","10"

The format of the performance information CSV file differs depending on the value specified for the -option parameter (resourceid_on_row or resourceid_on_column). When neither is specified, the output format is the same as when resourceid_on_row is specified.

• When resourceid_on_row is specified, each record is output for each collection time and resource. You can modify certain aspects of the CSV file format by editing the exportTool.properties file.

  • To determine whether the CSV header is included, set the value for the exportdata.isCsvHeader parameter. The default setting value is “output”.

    The following shows the content of the CSV header.

    "Date", "Time", "ID", "metrics name"

  • The record format is as follows:

    "YYYY/MM/DD","HH:MM","Resource ID","Performance value"

  • The record placement is one line per record.

    The following shows an output example of the CSV file:

    "Date","Time","ID","Total_IOPS"
    "2017/07/10","18:00","CL1-A/1122334455667788<HOST_A>","10"
    "2017/07/10","18:00","CL1-A/1122334455667788<HOST_A>","10"
    "2017/07/10","18:00","CL1-A/1122334455667788<HOST_A>","10"

• When resourceid_on_column is specified, one line contains performance information of multiple resources collected at the same time.. You can modify certain aspects of the CSV file format by editing the exportTool.properties file.
  • To determine whether the CSV header is included, set the value for the exportdata.isCsvHeader parameter. The default setting value is “TRUE”. If you specify FALSE (meaning that the CSV header is not included), an error occurs when the export data command runs.

    The CSV header includes the following information:

    CSV file name
    Serial Number: <Serial number>(<Storage model name>)
    From:
    To:
    Sampling
    "Date", "Time", "Resource ID",…," Resource ID "

  • The record format is as follows:

    "YYYY/MM/DD","HH:MM","Performance value", ..., "Performance value"

  • The record placement is one line contains performance information of multiple resources collected at the same time.

    The following shows an output example of the CSV file:

    Total_IOPS.csv
    Serial Number : 610025(VSP E790)
    From : 2021/09/20 23:40
    To : 2021/09/20 23:45
    Sampling : 5
    "Date","Time","CL1-A/1122334455667788<HOST_A>","CL1-A/
    1122334455667788<HOST_B>"
    "2021/09/20","23:40","10","10"
    "2021/09/20","23:45","10","10"
