Exporting storage system performance information

Storage Advisor Embedded offers two different methods of exporting performance data.

  • Use the CSV export tool in individual volume performance monitor reports to export performance information that is currently shown in the reports. You can use this information for quick analysis.
  • Use Export Tool 2 to export the performance information accumulated by your storage system. You can also use this tool to save and accumulate data over extended periods of time for long-term analysis and future reference.

Both tools output information in CSV format. You can analyze the CSV by using any spreadsheet software.

Exporting performance data for a volume to a CSV file

Export performance data for volumes to save and analyze it.

You can view real-time performance data for a single volume and export it. If the OS of the management client is Windows Server and the browser is Internet Explorer, disable Internet Explorer Enhanced Security Configuration, or use Google Chrome.

If you observe anything unusual in the operating status of a volume, you can export up to five minutes of data for evidence.

Procedure

  1. In the dashboard, click Volumes, and then click a volume name to open the volume detail page.

    Data displays in the Performance Monitor after a brief period of time.
  2. Click CSV Export in any of the three graphs.

Exporting performance data using the Export Tool 2

Export Tool 2 allows you to export the performance information accumulated by your storage system. By exporting and storing the information, you can analyze health status, troubleshoot, and predict future storage performance. You can also use Export Tool 2 to save and accumulate data over extended periods of time for long-term analysis and future reference. The performance information exported by Export Tool 2 is output in CSV format. You can analyze the CSV by using spreadsheet software. For details, see Using Export Tool 2.

Some typical reasons to export past performance data are:

  • A performance issue is found in some part of the environment, such as servers or the network.
  • There is a need to analyze peak time to use when considering workload splitting.
  • To analyze long-term performance trends, and aid in deciding when to expand the environment.

Checking and changing the collection interval of the performance information

From Export Tool 2, you can access the storage system and specify the collection interval of the performance data. The default interval is 5 minutes, and the collected data is updated daily. You can set the collection interval between 5 and 60 minutes in multiples of 5. If the collection interval is 60 minutes, the data can be retained for 12 days.

Before you begin

  • Install Export Tool 2. For details, see Installing Export Tool 2.
  • Register a user account to which only the Storage Administrator (Performance Management) role is assigned.

Procedure

  1. Open the Windows command prompt or the Linux terminal on the computer on which Export Tool 2 is installed.

  2. Go to the Export Tool 2 installation directory.

  3. Use the show interval command to check the collection interval set on the storage system.

    Specify the IP address of the management port of the storage system in the -ip parameter.

    Specify the user account and password in the -login parameter.

    In Windows :

    runWin.bat show interval –ip 192.168.0.16 -login export_user tropxe00

    In Linux :

    runUnix.sh show interval –ip 192.168.0.16 -login export_user tropxe00
  4. To change the collection interval, use the set interval command.

    Specify the collection interval in the -interval parameter. The collection interval can be set between 5 and 60 minutes in multiples of 5.

    In Windows :

    runWin.bat set interval –ip 192.168.0.16 -login export_user tropxe00 –interval 10

    In Linux :

    runUnix.sh set interval –ip 192.168.0.16 -login export_user tropxe00 –interval 10
  5. Close the Windows command prompt or the Linux terminal.

Exporting the performance information

From Export Tool 2, access the storage system and output the performance data, specifying an output directory of the CSV file, a time range, and a performance metrics group.

Before you begin

For details about the performance metrics and the performance metrics group names, see Outputting the performance information file.

The user must have Storage Administrator (Performance Monitor) role assigned.

Procedure

  1. On the computer where Export Tool 2 is installed, open the Windows command prompt or the Linux terminal.

  2. Navigate to the Export Tool 2 installation directory.

  3. Verify the collection time of the performance data accumulated in the storage system.

    Use the show range command to specify the IP address of the management port of the storage system in the -ip parameter.

    Specify the user account and password in the -login parameter.

    In Windows:

    runWin.bat show range –ip 192.168.0.16 -login export_user tropxe00

    In Linux:

    runUnix.sh show range –ip 192.168.0.16 -login export_user tropxe00

    Output Example:

    2017/03/31 12:20:30
    2017/03/31 12:30:30
    :
    2017/04/01 12:10:30
  4. Output the performance data to a file.

    Specify the output directory path in the -outpath parameter. When omitted, the performance data is output under the installed directory (monitor2\out).

    Specify a time range for the performance data that you want to output in the -range parameter. When omitted, the performance data accumulated in the storage system for the entire period is output.

    Specify a performance metrics group name that you want to output in the -group parameter. When omitted, all groups are output.

    Specify the option in the -option parameter. To compress the performance information in zip format, enter compress. For no compression, enter nocompress. When omitted, the option is set to compress. If a file or folder with the same name exists in the output directory of the file, enter ask to prompt whether to delete the file or folder. To delete the file or folder, enter clear. When omitted, the option is set to clear.

    In Windows:

    runWin.bat export data –ip 192.168.0.16 -login export_user tropxe00
     –outpath c:\\exportlog -range  201704010020:201704011210
     –group MP ParityGroup LDEV LU Port –option noncompress clear

    In Linux:

    runUnix.sh export data –ip 192.168.0.16 -login export_user tropxe00
     –outpath c:\\exportlog -range  201704010020:201704011210
     –group MP ParityGroup LDEV LU Port –option noncompress clear

    Output Example:

    +----+----+----+----+----+----+----+----+----+----+
    ===================================>                 70.0%

    The progress state and the progress rate are displayed.

    When the performance data output is complete, 100.0% is displayed for the progress rate.

  5. Close the Windows command prompt or the Linux terminal.
