Hello @Malta Virtual Mall , Thanks for using Microsoft Q&A Platform.
The Azure Monitor alerts works best in your use case, so try to create a Metric alert rule. An alert rule monitors over your data and detects any signals that indicate an event is occurring on a particular resource. The rule captures the signal and evaluates whether it meets the criteria of the specified condition.
Try to create an alert rule for Total Calls
navigate to the Azure portal->Bing resource-> Metrics-> New Alert rule by setting the Alert logic and threshold value.
Please go through this documentation to learn about Metric Alert rule: https://learn.microsoft.com/en-us/azure/azure-monitor/alerts/alerts-create-metric-alert-rule
I hope this helps.
Regard,
Vasavi
