</p><p><strong>Metric object</strong>:Select the monitoring Metric object for which we need to configure the threshold.

<strong>Threshold trigger expression</strong>:Calculate and judge whether to trigger the threshold according to this expression. See the page prompts for expression environment variables and operators. Eg:set the response time greater than 50 to trigger an alarm, and the expression is <code>responseTime &gt; 50</code>. For detailed help on threshold expression, see <a href="/docs/help/alert_threshold_expr">Threshold expression help</a><br>
<strong>Alarm level</strong>:The alarm level that triggers the threshold, from low to high: warning, critical, emergency.<br>
<strong>Trigger times</strong>:How many times will the threshold be triggered before the alarm is really triggered.<br>
<strong>Notification template</strong>:Notification information Template sent after alarm triggering, See page prompts for template environment variables, eg:<code>${app}.${metrics}.${metric} Metric&#x27;s value is ${responseTime}, greater than 50 triggers an alarm</code><br>
<strong>Global default</strong>: Set whether this threshold is valid for such global Metrics, and the default is No. After adding a new threshold, you need to associate the threshold with the monitoring object, so that the threshold will take effect for this monitoring.<br>
