I'm planning on using Amazon Comprehend for some trial project, but I would like to stay within limits of the free tier. For this reason, I need to set up an alarm on CloudWatch to get informed when I reach said limits.

However, I am unable to select "Amazon Comprehend" from the list of services to monitor.

Can I get some assistance?

From AWS Free Tier, the limits for Amazon Comprehend are:

  • 50 K units of text (5M characters) for each API per month (50,000 units @ $0.0001/unit = $5 of value)
  • 5 Topic Modeling Jobs up to 1MB each per month for the first 12 months (5 @ $1 = $5 value)

So, the free tier provides up to $10 of value each month.

Accordingly to AWS Services That Publish CloudWatch Metrics - Amazon CloudWatch, Amazon Comprehend does not publish metrics to Amazon CloudWatch.

Therefore, your best method would be to monitor the Top Free Tier Services by Usage dashboard in the AWS management console to keep a track of Free Tier usage. You should also receive an email when a Free Tier quantity is close to being exceeded.
