I have a custom metric with many dimensions. Can I setup an alarm against the value of a dimension instead of the metric?

1Question is unclear. How can you setup an alarm on a dimension? Explain the problem with an example. – helloV Feb 27 '17 at 18:21

Say I have 4 dimension key/pair combinations. I would like to setup an alarm against the value of each individual dimension. – user2202911 Feb 27 '17 at 18:22

Still unclear. Can you edit your question giving some concrete examples of what you want to achieve? – Matt Houser Feb 27 '17 at 18:57

If one dimension reaches a certain threshold or value, trigger the alarm. – user2202911 Feb 27 '17 at 21:02

You can't. A metric is identified by a set of dimensions and a namesapce. If you change a dimension value, well then you've created a new metric. You can only alarm on metric datapoint values.
See CloudWatch Concepts for clarification.
