Configuring a Collection Policy

Configuring a Collection Policy

After the Collection Switch is enabled, configure a collection policy for the system based on service characteristics. This policy will be synchronized to SystemReporter. You can customize a policy to suit service requirements in a specific application scenario.

Procedure

  1. Go to the Collection Policy dialog box.

    1. On the top navigation bar of the SystemReporter user interface, click System.
    2. In the left navigation tree, choose System Configuration > Registration and Configuration.
    3. From the list of registered devices in the right function pane, select the storage system for which you want to configure a collection policy.
    4. Click Collection Policy.

      The Collection Policy dialog box is displayed.

  2. Configure a collection policy.

    1. Configure a collection policy. Table 3-4 describes the related parameters.
      Table 3-4 Parameters of a collection policy

      Parameter

      Description

      Value

      Real-time monitoring

      Real-time data collection period.

      [Value range]

      5, 10, 30, or 60, expressed in seconds.

      When a storage system is registered, the value of this parameter is the value of Sampling Interval of Real-Time Statistics Collection (s) set in the storage system.

      NOTE:

      If you click Restore Defaults, the value of Real-time monitoring is 5 seconds.

      [Example]

      5 seconds

      Historical monitoring

      Historical data collection period.

      [Value range]

      5 seconds, 1 minute, 2 minutes, 5 minutes, 10 minutes, 30 minutes, or 60 minutes.

      When a storage system is registered, the value of this parameter is the value of Sampling Interval of Historical Statistics Collection (s) set in the storage system.

      NOTE:

      If you click Restore Defaults, the value of Trend is 1 minute.

      [Example]

      1 minute

      Current capacity can store approximately

      Number of days when the remaining availability of the disks for storing performance data.

      NOTE:

      The value of Historical monitoring affects this parameter because storage space is mainly occupied by historical data.

      The parameter value is set by default and cannot be changed.

      Save historical monitoring data on the device

      • When this parameter is set to Enabled, performance monitoring files are saved in the storage system. Every controller of the storage system can save performance monitoring files onto coffer disks. The file save path is /OSM/coffer_data/perf/perf_files/. All files saved by controllers compose complete performance data. Dump historical performance monitoring files in time because every controller provides only 652.8 MB space to store the files. Files not dumped in time will be overwritten by new files.
      NOTE:

      You can query, delete, and export performance monitoring files in the storage system, using CLI commands.

      • Run the show performance file command to query the performance monitoring files saved in the storage system.
      • Run the delete performance file command to delete performance monitoring files from the storage system.
      • Run the export performance file command to export performance monitoring files from the storage system. The exported performance monitoring files can be viewed using SystemReporter. For details, see the corresponding SystemReporter user guide.

        For details about how to use the commands, see the Command Reference of the corresponding product model.

      • When this parameter is set to Disabled, performance monitoring files are not saved. In this case, historical performance data will not be displayed in the trend view of SystemReporter.
        NOTE:

        To facilitate storage device maintenance, select Enabled for Save historical monitoring data on the device.

      [Value range]

      Enabled or Disabled

      [Default]

      Enabled

      Automatic stop

      If this function is enabled, the performance Collection Switch is disabled automatically when the specified cycle expires.

      [Value]

      Enabled or Disabled. If Automatic stop is enabled, the automatic stop cycle ranges from 1 to 31 days.

      [Example]

      Disabled

    2. Click OK.

      The Information dialog box is displayed, indicating that the collection policy is successfully configured.

    3. Click OK.
