Can I use packetbeat or some other mechanism to monitor search queries hitting my AWS OpenSearch cluster?

Hi, I'm trying to find a good way to monitor search queries hitting our AWS OpenSearch cluster.

Use case: We have dozens of different applications that send queries to the cluster, some in response to user requests, some based on a cron schedule or other background activities. I need a way to analyze the volume of different types of queries being processed, average elapsed time for each type of query (e.g. by index and/or some normalized query pattern).

The most promising option I've found searching on the web for this problem is packetbeat. See https://www.elastic.co/blog/monitoring-the-search-queries for details on this setup. So, I'm wondering:

• Is it possible to monitor AWS OpenSearch cluster using packetbeat?
• Is there an alternate or better way to achieve what I described above?

I'm aware of slow query logging. This is somewhat helpful but not sufficient for my needs.

We are currently running elasticsearch version 6.8, so ideally looking for a solution that is compatible with that version, but we are also planning to upgrade next year to a newer version so I am interested in solutions that work with newer versions as well. Thanks!
