A company's web app publishes JSON logs with transaction status to CloudWatch Logs. The company wants a dashboard showing the number of successful transactions with the least operational overhead.Which solution meets this?
C) Create a CloudWatch metric filter on the log group with a pattern matching success; create CloudWatch dashboard with metric graph.
A) Create an OpenSearch cluster and subscription filter to send logs; create OpenSearch dashboard with queries for success.
B) Create a CloudWatch subscription filter with Lambda to parse logs and publish custom metrics; create CloudWatch dashboard with metric graph.
D) Create a Kinesis data stream subscribed to the log group; filter logs by success; send to Lambda; Lambda publishes custom metrics; dashboard uses metric graph.

A company's web app publishes JSON logs with transaction status to CloudWatch Logs. The company wants a dashboard showing the number of successful transactions with the least operational overhead.

Which solution meets this?

Show Suggested Answer Hide Answer
Suggested Answer: C

CloudWatch metric filters can parse logs directly to create metrics without additional infrastructure.

Metric filters combined with CloudWatch dashboards provide the simplest and most operationally efficient solution.

Options A, B, and D add complexity with additional services (OpenSearch, Lambda, Kinesis).

I’m a bit uncertain about Kinesis; it seems like overkill for just counting successful transactions. I lean towards option C as well.

I practiced a similar question where we had to choose between CloudWatch and OpenSearch. I feel like option C could be the simplest approach here.

I think option B sounds familiar; using Lambda to parse logs could be effective, but it might add more complexity than necessary.

I remember we discussed using CloudWatch for monitoring, but I'm not sure if the metric filter is the best option for this scenario.
