 8. Create an **Expression** to monitor by selecting a **Metric**, **Operator**, and **Trigger value**.
 
    * For **Metric**, select the type of condition you want monitored.  **Bandwidth Mbps** is the amount of bandwidth usage in megabits per second.  **Total Connections** is the number of concurrent HTTP connections to our edge servers.  For definitions of the various cache statuses and status codes, see [Azure CDN Cache Status Codes](https://msdn.microsoft.com/library/mt759237.aspx) and [Azure CDN HTTP Status Codes](https://msdn.microsoft.com/library/mt759238.aspx)
    * **Operator** is the mathematical operator that establishes the relationship between the metric and the trigger value.
-   * **Trigger Value** is the threshold value that must be met before a notification will be sent out.
+   * **Trigger Value** is the threshold value that must be met before a notification is sent.

-    * **Condition Start** indicates that a notification will be sent when the specified condition is first detected.
-    * **Condition End** indicates that a notification will be sent when the specified condition is no longer detected. This notification can only be triggered after our network monitoring system detected that the specified condition occurred.
-    * **Continuous** indicates that a notification will be sent each time that the network monitoring system detects the specified condition. Keep in mind that the network monitoring system will only check once per interval for the specified condition.
-    * **Condition Start and End** indicates that a notification will be sent the first time that the specified condition is detected and once again when the condition is no longer detected.
