Modifying performance monitors

Edit online

To modify all of the performance monitors that are used by IBM Spectrum Control, use the Performance Monitors page in the web-based GUI. To modify performance monitors for specific resources, use the resource list and resource detail pages.

Before you begin

To modify performance monitors, you must have Administrator privileges.

About this task

You can modify the schedule for multiple performance monitors at the same time.

You can enable or disable performance monitors and modify the interval. The interval represents the number of minutes over which samples of performance data are averaged.

Procedure

  1. In the menu bar in the web-based GUI, go to Home > Performance Monitors.
    Detailed information about all performance monitors is shown in the Performance Monitors tab.
  2. Locate the performance monitors that you want to modify.
  3. Select the performance monitor rows and click Actions > Schedule.
  4. On the Data Collection Schedule window, modify the schedule for the performance monitors.
    If you select multiple performance monitors, the following rules are used to determine the field settings when you open the Data Collection Schedule window:
    • If all of the performance monitors that you select are enabled, the Enabled value is displayed. If all of the performance monitors are disabled, the Disabled value is displayed. Otherwise, the state field for the performance monitors is blank.
    • If the performance monitors have different interval values, the interval field is blank. If the performance monitors have the same interval value, the value is displayed.

      Intervals that are common to all performance monitors that you select are displayed in the interval list. For example, you select performance monitors for two storage systems. Storage_System_a specifies performance monitor intervals of 5 minutes, 10 minutes, and 15 minutes. Storage_System_b specifies intervals of 10 minutes, 15 minutes, and 20 minutes. The interval list displays intervals of 10 minutes and 15 minutes.

  5. Click Save.

Results

The changes are applied to all the performance monitors that are selected. The performance monitors run according to the modified schedule. If you disabled a performance monitor, IBM Spectrum Control stops collecting performance metrics for the storage system or switch.

What to do next

To check the progress of the performance monitors, you can complete the following actions on the Performance Monitors page:
  • View information such as the status of the performance monitor and the most recent date and time when performance data was collected about a resource.
  • Right-click the performance monitor row, and select Open Logs. You can view detailed informational, warning, and error messages that are related to the performance monitor job. Use this information to troubleshoot any errors that might occur when the job runs.
