Types

type GceInterface

type GceInterface interface {
	GetSecret(ctx context.Context, projectID, secretName string) (string, error)
}

GceInterface defines an interface for the GCE client to allow faking.

type MySQLMetrics

type MySQLMetrics struct {
	Config *configpb.Configuration

	WLMClient      workloadmanager.WLMWriter
	DBcenterClient databasecenter.Client
	// contains filtered or unexported fields
}

MySQLMetrics contains variables and methods to collect metrics for MySQL databases running on the current host.

func New

func New(ctx context.Context, config *configpb.Configuration, wlmClient workloadmanager.WLMWriter, dbcenterClient databasecenter.Client) *MySQLMetrics

New creates a new MySQLMetrics object initialized with default values.

func (*MySQLMetrics) CollectDBCenterMetricsOnce

func (m *MySQLMetrics) CollectDBCenterMetricsOnce(ctx context.Context) error

CollectDBCenterMetricsOnce collects metrics to send to Database Center for MySQL databases running on the host.

func (*MySQLMetrics) CollectWlmMetricsOnce

func (m *MySQLMetrics) CollectWlmMetricsOnce(ctx context.Context, dwActivated bool) (*workloadmanager.WorkloadMetrics, error)

CollectMetricsOnce collects metrics for MySQL databases running on the host.

func (*MySQLMetrics) InitDB

func (m *MySQLMetrics) InitDB(ctx context.Context, gceService GceInterface) error

InitDB initializes the MySQL database connection.
