Answer 1

Hello @Elisha George ,

Welcome to the Microsoft Q&A platform. Happy to answer your question.

To answer your query pricing depends on what kind of alerts you are going to configure. For details on usage on costs, refer to this article and An alert rule is charged based on the type and number of signals it monitors. A signal can be a resource metric, a log or an activity log. The cost of an alert rule that monitors multiple signals is the sum of the cost of monitoring each signal and any enabled features.

For details, refer to the following link Pricing-Alert-Monitor

Dynamic alert is billed for the dynamic threshold capability and the underlying metric alert.

Examples:

The price of an alert rule which monitors the CPU utilization, and RAM usage (i.e. 2 metric time-series) for 10 VMs, and has dynamic threshold enabled, can be calculated as,

Price of alert rule + Price of dynamic threshold.
(10 VMs * 2 metric time-series per VM – 10 free units) * $0.10 per metric time-series alert rule per month + [(10 VMs * 2 metric time-series per VM) * $0.10 per dynamic threshold per month] = $3 per month.
The price of an alert rule which queries 1 Log analytics workspace for a ‘404-error’ event every 15-minutes can be calculated as,

1 workspace * 1 log alert query * $0.50 per log alert rule per month = $0.50 per month.
So, you will pay $0.10 for 1 metric (what you see in Calculator) and + $0.10 for dynamic threshold.

1 metric with static threshold costs $0.10

1 metric with dynamic threshold costs $0.20 (1 metric $0.10 + 1 dynamic threshold $0.10)

For 10 firsts metrics you will pay only dynamic threshold which is $0.10, or for 10 firsts with static threshold $0.00

Some of these pricing related queries are already answered under FAQs section at Alerts-FAQs
For example :
How will I be billed for a log alert rule with dimensions?
The price of an alert rule which queries 1 resource event every 15-minutes can be calculated as,
Total monthly price = 1 resource * 1 log alert rule * price per 15-minute internal log alert rule per month
