Description

The following messages have been found in the v4.9.0-alpha3 AMI related to a cache_maxsize warning

We need to determine the origin of this warning and why it is appearing

However, it doesn't seem to happen under 2.15:

It looks like this was addressed in this PR:

• Fixed the bug in CacheConfigMetricsCollector opensearch-project/performance-analyzer#657

Bumping our fork to 2.15 should get rid of the warning as well.

Closing as this is already fixed in upstream OpenSearch.
