Number of Dimensions Support for Metric Filters in AWS CloudWatch

Question

As part of our application monitoring and analysis, we heavily rely on AWS CloudWatch for collecting and analyzing various metrics. While the existing functionality has been instrumental in our monitoring efforts, we have encountered a requirement to expand the number of dimensions associated with our metric filters.

Presently, I am aware that Metric Filters in AWS CloudWatch support up to three dimensions. However, due to the evolving needs of our application and the increasing complexity of our infrastructure, we have reached a point where we require additional dimensions to capture more granular data for effective monitoring and troubleshooting.

To optimize our monitoring capabilities and gain deeper insights into our system's performance, I kindly request your assistance on the following inquiries:

1. Is there any way to increase the number of dimensions supported by Metric Filters in AWS CloudWatch?
2. If it is possible to increase the dimensions, what is the recommended approach or any available workarounds?
3. Are there any considerations or best practices we should be aware of when working with an increased number of dimensions in Metric Filters?

Answer

Up to three settings can be made as described in this document.  
There is currently no way to increase this value.

> You can use the CloudWatch console or AWS CLI to create metric filters that publish dimensions with metrics that JSON and space-delimited log events generate. Dimensions are name/value value pairs and only available for JSON and space-delimited filter patterns. You can create JSON and space-delimited metric filters with up to three dimensions. For more information about dimensions and information about how to assign dimensions to metrics, see the following sections:
