Database Monitoring runs on top of the base Datadog Agent. By default, it’s configured with optimal performance settings to minimize impact on your system. However, you have the flexibility to adjust parameters like data collection frequency and query sampling to better suit your workloads.
This page contains the results of integration overhead tests conducted against databases with Datadog Database Monitoring enabled.
Postgres integration overhead tests were run on an Amazon EC2 machine c5.xlarge
instance (4 vCPUs, 8 GB RAM). The database used for the tests was a PostgreSQL 14.10 instance running on an Amazon RDS db.m5.large
instance (2 vCPUs, 8 GB RAM). The database was running a TPC-C workload with 20 warehouses.

Note: The network bandwidth is the sum of the incoming and outgoing traffic from the Agent to the monitored database and the Datadog backend.
MySQL integration overhead tests were run on an Amazon EC2 machine c5.xlarge
instance (4 vCPUs, 8 GB RAM). The database used for the tests was a MySQL 8.0 instance running on an Amazon RDS db.m5.large
instance (2 vCPUs, 8 GB RAM). The database was running a TPC-C workload with 20 warehouses.
