# Troubleshooting DBM Setup for Amazon DocumentDB

This page details common issues with setting up and using Database Monitoring with Amazon DocumentDB, and how to resolve them. Datadog recommends staying on the latest stable Agent version and adhering to the latest [setup documentation](https://docs.datadoghq.com/database_monitoring/setup_documentdb/), as it can change with Agent version releases.
