如果您还不熟悉DB 2，或者您不确定将什么定义为计数器的警告和问题级别，或者甚至不知道应该查看什么计数器，您可以使用一个预定义的阈值模板。
If you are new to DB2 or you are not sure what to define as warning and problem levels for counters or even what counters you should be looking at, use one of the predefined threshold templates.
您可以修改和保存这些预定义阈值集模板，或者可以从头创建您自己的模板。
You can modify and save these pre-defined threshold set templates, or you can create your own template from scratch.
例如，如果某个特定计算机的CPU使用率达到了预定的阈值(例如85%)，则监视系统应向操作员发出警报。
For example, if the CPU utilization on a particular machine approaches a pre-determined threshold (for example, 85%), the monitoring system should alert the operator.
系统还可以标出某些目录中超过预定义阈值的所有消息以便进行特殊处理。
The system can also flag all messages with certain categories over a pre-defined threshold for special processing.
可以使用自定义阈值对这些预定义境况进行配置，也可以定义自定义境况来监视服务的特定属性。
You can configure these predefined situations with custom threshold values, or you can define custom situations to monitor specific attributes of the services.
相反的，当虚拟系统的使用在某段时间内低于预定义的阈值，空闲的节点就被删除、或者内存就被收回。
Conversely, when the usage of a virtual system is lower than the predefined threshold for a certain time, idle nodes are removed or memory is drawn back.
无论任何时候，只要服务质量降低到预定义的阈值，都应当及时将问题报告给IT部门。
Whenever there is a service quality degradation under the predefined threshold, the problem should be reported to the it department in a timely manner.
当Web服务导致错误时(如web服务的消息大小或响应时间超过配置的阈值时)，将触发特定的预定义境况。
Certain predefined situations are triggered when there are faults caused by Web services, such as when message sizes or response times for the Web services exceed the configured thresholds.
在大多数预先设定的阈值与预定的临界水平和热表面(中期)温度探测器温度应用程序不完全相同。
In most applications the pre-set threshold temperature of probes with predetermined threshold levels and the temperature of the hot surface (of the medium) are not exactly the same.
负载反应单元(9)优选地包括流体压力单元，指示器(60)包括在预定压力阈值下操作的机械指示器。
The load reacting unit (9) preferably comprises a fluid pressure unit and the indicator (60) comprises a mechanical indicator that operates at a predetermined pressure threshold.
重复上述步骤，直到差异比预定的阈值小。
The above steps are repeated until the discrepancies are smaller than a predetermined threshold.
晶体管元件包括预定的阈值电压。
The transistor element comprises a predefined threshold voltage.
晶体管元件包括预定的阈值电压。
The transistor element comprises a predefined threshold voltage.
