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.
这个参数允许使用色彩配置来突出不同的水平，同时还能标明每个矩阵中警告或者错误的阈值。
The preferences allow configuration of the colours used to highlight the different levels, as well as the thresholds for warnings and errors for each metric.
当问题严重程度到达警告和错误的阈值时，能够以电子邮件或者纸质的方式向管理员发送告警信息。
Alerts can be sent using email or pager to the on-call administrator when problems reach warning and error thresholds.
例如，您可以定义当BufferPoolHitratio下降到低于60%时触发一个警告级阈值提醒，或者低于55%时触发一个问题级阈值提醒。
For example, you can define a threshold alert to be triggered if your Buffer Pool Hit ratio drops to below 60% for a warning level or 55% for a problem level.
