dbm query monitoring for read replicas

Thanks for the awesome dbm feature for database monitoring. We use a master/standby system where all the interesting stuff happens on the standby queries since they get the live traffic. I’m integrating the database monitoring and am curious how datadog’s DBM monitoring will work if pointed at a read replica?

If it’s pointed at a read replica, it will be unable to write to the datadog schema. Does that mean query samples are not supported for read replicas? Any thoughts on how to get query samples for read replicas?

Thanks!

You’re correct about the function. That said, there’s a simpler answer to this problem.

Usually, the setup steps which include creating the schema and function happen on the primary instance which then gets replicated to the replica and enables the agent integration to use the function (and schema along with access grants). So unless you don’t want to run the setup on the primary for some reason, you shouldn’t have issues getting the agent integration working.

Let me know if that helps clarify things!
