Contributors
PDFs

You can create performance policies that trigger alerts to notify you when thresholds for Storage Pool assets have been exceeded.

Before you begin

This procedure assumes that you have thin provisioned the storage pool.

About this task

You want to create policies that monitor and report changes in a storage pool that could contribute to outages. For the thin provisioned physical storage pool, you want to monitor the physical capacity and monitor the Overcommit Ratio.

Steps

  1. Open OnCommand Insight in your browser.

  2. Select Manage > Performance Policies

    The Performance Policies page is displayed. Policies are organized by object, and are evaluated in the order in which they appear in the list. If notifications are enabled (Admin > Notifications), you can configure Insight to send email when performance policies are breached.

  3. Click +Addto create a new policy.

  4. In Policy Name enter a policy name for the Storage Pool.

  5. In Apply to objects of type select Storage Pool.

  6. In Apply after window of enter First occurrence.

  7. In With severity enter Critical

  8. Configure the Email recipients that you want notified when thresholds are breached.

    By default, email alerts on policy violations are sent to the recipients in the global email list. You can override these settings so that alerts for a particular policy are sent to specific recipients.

    Click the link to open the recipients list, then click the + button to add recipients. Violation alerts for this policy will be sent to all recipients in the list.

  9. In Create alert if any of the following are true enter Capacity ratio - Used > 85%

Results

This configuration results in the system sending a critical warning message when more than 85% of the physical capacity of the storage pool is used. Using 100% of the physical memory will result in application failure.

Create additional Storage Pool policies

About this task

Create an additional “Capacity ratio - Used” policy that raises a warning message when the Storage Pool capacity used exceeds 75%. If notifications are enabled (Admin > Notifications), you can configure Insight to send email when performance policies are breached.
