Neon has integrated with Datadog to monitor key metrics of your database during its beta phase. The Business Plan currently supports this integration, and users can request it for the Scale plan as well. Metrics exposed to Datadog include connection counts, replication delay, compute metrics, Local File Cache metrics, working set size, and Postgres statistics. By monitoring these metrics, Neon users can optimize their databases' performance and detect potential issues in replication processes or connection pooling strategies.
