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.

选择应用的设备

  • 应用到所有设备。默认情况下，阈值会监控所有适用的主机。

    排除设备。选择以构建或应用排除列表。

  • 单击将此阈值应用于特定设备以选择应用阈值的主机。
    注： 配置阈值检查间隔时间时，请设置成比趋势相关阈值（例如使用率）采样间隔时间更长。配置状况检查临界值时，请将其配置成与取样间隔时间相同（或类似）。
