Track device performance using monitors and thresholds you choose. See abnormally spiked or light periods for one or more devices. Track overall trends against expected service level for many devices.

Configure a custom performance monitor threshold:

  • Name. Used in the Threshold library and the title on the Alert Center Home page.
  • Select Custom performance monitor.
    • Select Scope. All devices (Global) versus selected devices (Device specific monitors)
    • Select a monitor from the drop down list. For example, Select APC UPS, Printer, Active Script, SNMP, or WMI, and more.
    • Monitor. The configured monitors of the selected type. These are the monitors used to determine if the measured parameters have dropped below or exceeded threshold limits.
      注: When you select Global Monitors, this list is populated with custom performance monitors currently configured in the Monitor Library. When you select Device Specific Monitors, this list is populated with custom performance monitors currently configured for specific devices.
  • Threshold Check Interval. Enter a time interval for Alert Center to check the database for items that are out of the threshold limits.

    Automatically resolve items no longer out of threshold. Select this option if you want Alert Center to automatically resolve items when they return to the value within the threshold limit.

注: Notification policies are optional for most thresholds. If you do not select a notification policy, no notifications are generated for the threshold, but a dashboard report listing the out of threshold items still appears on the Alert Center Home page.

Thresholds

  • Average value. Choose a trend (Exceeds, Falls-below) and a value for the performance measurement. .
  • Duration. Specify a time range or "rolling interval" for calculating/totalling the performance measurement and comparing it to the threshold value.

適用されたデバイスの選択

  • [Apply to All Devices (すべてのデバイスに適用)]。デフォルトでは、しきい値は適用可能なすべてのホストを監視します。

    [デバイスを除外]。除外リストを作成または適用する場合に選択します。

  • [このしきい値を特定のデバイスに適用] をクリックして、しきい値を適用するホストを選択します。
    注: 使用率などの傾向に関連するしきい値には、しきい値チェック間隔にサンプリング間隔よりも長い時間を設定してください。正常性チェックのしきい値を設定する場合は、サンプリング間隔と同様の時間に設定してください。
