Which metric should you monitor?

Your company uses Azure Stream Analytics to monitor devices. The company plans to double the number of devices that are monitored.

You need to monitor a Stream Analytics job to ensure that there are enough processing resources to

handle the additional load.

Which metric should you monitor?
A . Input Deserialization Errors
B . Early Input Events
C . Late Input Events
D . Watermark delay

View Answer

Answer: D

Explanation:

There are a number of other resource constraints that can cause the streaming pipeline to slow down.

The watermark delay metric can rise due to:

– Not enough processing resources in Stream Analytics to handle the volume of input events.

– Not enough throughput within the input event brokers, so they are throttled.

– Output sinks are not provisioned with enough capacity, so they are throttled. The possible solutions vary widely based on the flavor of output service being used.

Incorrect Answers:

A: Deserialization issues are caused when the input stream of your Stream Analytics job contains malformed messages.
