Types

type GceInterface

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

GceInterface defines an interface for gce.GCEClient to allow faking

type PostgresMetrics

type PostgresMetrics struct {
	Config *configpb.Configuration

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

PostgresMetrics contains variables and methods to collect metrics for Postgres databases running on the current host.

func New

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

New creates a new PostgresMetrics object initialized with default values.

func (*PostgresMetrics) CollectDBCenterMetricsOnce

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

CollectDBCenterMetricsOnce collects metrics for Postgres databases running on the host.

func (*PostgresMetrics) CollectWlmMetricsOnce

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

CollectWlmMetricsOnce collects metrics for Postgres databases running on the host.

func (*PostgresMetrics) InitDB

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

InitDB initializes the Postgres database connection.
