Installing and Administering N1 Grid Console - Container Manager 1.0

Alarm Management

You can set alarm thresholds for a container's use of CPU and physical memory resources. Three levels of alarms are available: Critical, Major, and Minor. You can also request that an email be sent when alarms are generated. The alarms are displayed as icons in the navigation window and the Containers table. Each icon displays a tool tip containing alarm details when the cursor is placed over it.

The Container Manager GUI displays only those alarms generated by its own module. Alarms generated by the Container Manager module are visible in both the Sun Management Center Java and Web consoles in addition. If you will use Sun Management Center to view the Container Manager alarms, the alarm names match up according to the following table.

To Set an Alarm Threshold

  2. In the Hosts view, select the host with which the container is associated.

  3. Select the Containers tab in the right panel.

    A table appears that lists all containers that are associated with that host.

  4. In the table, select the name of the container for which you want to set an alarm.

    The Properties page for the container appears.

  5. Click the Alarm Thresholds tab.

    The alarm setting page appears. Three levels of alarms are available: Critical, Major, Minor.

  6. Locate the level of alarm to be set, and provide the alarm values in the text fields.

    Three alarm settings are available:

    • CPU Threshold Less Than – Provide an integer or decimal value. The alarm is triggered when the CPU level goes below the level.

    • Memory Threshold Greater Than – Provide an integer in Mbytes. The alarm is triggered when the memory level exceeds this level.

    • Mail To – Prove a valid email address. An email alert is sent to this address once the alarm is triggered.

    Note –

    You can set one, two, or three levels of alarms at once. If more than one alarm is triggered, the alarm with the highest value appears as an icon in the GUI. Likewise, an email alert is sent for the alarm with the highest value.

  7. Click Save.

    The alarm is now set.
