ServiceWatch Metrics

MariaDB sends metrics to ServiceWatch. The metrics provided by default monitoring are data collected at a 1-minute interval.

Reference

How to check metrics in ServiceWatch, refer to the ServiceWatch guide.

Basic Indicators

The following are the basic metrics for the MariaDB namespace.
