Mackerel supports obtaining and monitoring Database for PostgreSQL metrics in Azure Integration. Billable targets are determined using the conversion 1 resource = 1 Micro Host.
Please refer to the following page for Azure Integration configuration methods and a list of supported Azure services.
Azure Integration
Obtaining metrics
The following metrics can be retrieved for Database for PostgreSQL servers.
A maximum of 34 metrics (including 16 enhanced metrics) will be retrieved. Enhanced metrics can be retrieved by turning on the server parameter metrics.collector_database_activity. The actual metrics obtained may be reduced depending on the server SKU and role.
For Metric explanations and how to enable enhanced metrics, please refer to the Azure documentation.

Notes
- Of the graphs / metrics that can be obtained with Azure integration listed above, when obtaining Backup Storage used at the Basic price level, it is done so according to the specifications of the Azure Monitor API used by Azure integration, normally with a 15-minute interval granularity and updates having a latency of up to 30 minutes.
