    • Select the task group and the scheduler to which you want to assign the ETL task.
  3. Click Schedule. A message confirming the scheduling job submission is displayed.
    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. Testing the connection to the EMC SMI-S Provider

The ETL relies on XtremIO Management Server to collect information about EMC XtremIO storage systems. Because some connectivity issues may exist and cause the ETL to fail, it is highly recommended to test the connection to this specific component. The procedure is as follows:

  1. Download the troubleshooting tool from EPD.
  2. Run the command java –jar <Troubleshooting_Tool_Name.jar> to launch the tool.
  3. Enter the information required to connect to the system and click Test Connection.
  4. Wait for the test to complete.
  5. If a connectivity issue is detected, an error message will appear. In this case, the issue encountered does not concern the ETL. Check your configuration to diagnose the source of the issue.
  6. Click Save As to export the connection test results into a txt file.


B. 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_CONFIGURED_VOLUME_CAPACITY (Configured Volume Capacity)
  • ST_DEVICECOUNT (Number of Volumes)
  • ST_HOSTCNT (Number of Hosts)
  • ST_SYSTEM_SUBSCRIBED_CAPACITY (Storage Subscribed Capacity)

To customize volumes monitoring

  1. Edit the EMC XtremIO Management Server 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.

C. Running the Extractor Service task
