    When the ETL runs as scheduled, it collects data from the source and transfers it to the TrueSight Capacity Optimization database.

Step IV. Post-configuration steps

A. Customizing volumes monitoring

Discovering volumes and collecting their performance metrics are resource-intensive actions that can create extra workload on the system. To reduce the system resource consumption, administrators can disable or enable the volumes monitoring at will and fine-tune the creation of volume entities into the TrueSight Capacity Optimization environment.

The following metrics are no longer collected and displayed in the console when volumes monitoring is disabled:

DatasetMetrics
STOGLB
  • ST_CONFIGURED_VOLUME_CAPACITY_PCT (Storage System Configured Capacity Percentage)
  • ST_OVERSUBSCRIBED_CAPACITY (Storage Oversubscribed Capacity)
  • ST_POOL_OVERSUBSCRIPTION_SITUATION (Pool Oversubscription Situation)
  • ST_POOL_SUBSCRIBED_CAPACITY (Pool Subscribed Capacity)
  • ST_POOL_SUBSCRIBED_CAPACITY_PCT (Pool Subscribed Capacity Percentage)
  • ST_SYSTEM_SUBSCRIBED_CAPACITY (Storage Subscribed Capacity)
  • ST_VOLUME_CONSUMED_CAPACITY (Volume Consumed Capacity)
  • ST_VOLUME_CONSUMED_CAPACITY_PCT (Volume Consumed Capacity Percentage)
  • ST_VOLUME_HOST_VISIBLE_CAPACITY (Host Volume Visible Capacity)
  • ST_VOLUME_MAPPED (Volume Mapped)
  • ST_VOLUME_RESPONSE_TIME (Volume Response Time)
  • ST_VOLUME_TIME_SINCE_LAST_ACTIVITY (Volume Time Since Last Activity)
  • ST_VOLUME_TRANSFER_BYTE_RATE (Volume Transfer Byte Rate)
STOHOST
  • BYHOST_ALLOCATED (Allocated Space by Host)
  • BYHOST_SIZE (By Host Physical Size)


To customize volumes monitoring

  1. Edit the ETL Run Configuration.
  2. Expand the ETL additional settings menu.
  3. From the Volumes pull-down lists, select one of the following options:

    OptionResult
    Disabled
    • Volumes are not discovered.
    • Volumes-related metrics are not loaded in the console.

    Note

    Use this configuration if the number of volumes to manage significantly slows down the system performance. Disabling the volumes monitoring prevents the discovery of volumes and consequently does not allow the ETL to collect, save or process their data. Note that the calculation of metrics for other sources may be impacted.
    Collected for metric computation (Default)
    • All volumes are discovered and their metrics are collected and processed.
    • Volumes-related metrics are not loaded in the console.

    Note

    Use this configuration if you wish to collect and process volume-related metrics without loading this information in the console. The collected data will however be used to calculate metrics for other sources, when required. This will reduce the resource consumption of your system.

    Collected and Imported
    • All volumes are discovered and their metrics are collected and processed.
    • Volumes-related metrics are saved in the database, processed and loaded in the console.

    Note

    Use this configuration if your system is powerful enough to manage all the volumes to monitor.

  4. Click Save.

B. Running the Extractor Service task

 Extractor settings
