Databases metrics and dimensions

This topic covers the metrics, dimensions, and system alert parameter values for Databases.

Metric	API equivalent	Description	Units
Available Disk Space	`available_disk`	Amount of storage space on a disk drive that isn’t currently in use	GB
Available Memory	`available_memory`	Amount of memory available to be allocated to new or existing processes	GB
CPU Usage	`cpu_usage`	Percentage of the available CPU capacity used by the compute instance hosting the database, which reflects the load handled by individual processor cores while executing database operations and supporting processes	%
Disk I/O Read	`read_iops`	Number of read operations a storage disk can perform per second	IOPS
Disk I/O Write	`write_iops`	Number of write operations a storage disk can perform per second	IOPS
Disk Space Usage	`disk_usage`	Percentage of a Linode's disk capacity in use by database processes and stored data	%
Memory Usage	`memory_usage`	Percentage of a Linode's memory in use by the database engine	%

Dimension	API equivalent	Description
Database Cluster	`database_cluster`	The specific group of databases or servers connected to a system
Database Engine	`database_engine`	The underlying system that the database is using to operate: MySQL or PostgreSQL
Node Type	`node_type`	The type of node in a cluster: `primary` or `secondary`
Region	`region`	The localized geographic area where the entity is located
