Functions

func BuildResource

func BuildResource(namespace string, args ...string) (pb.Resource, error)

BuildResource parses input strings, typically from CLI flags, to build a Resource object for use in the protobuf API.

func BuildStatSummaryRequest

func BuildStatSummaryRequest(p StatSummaryRequestParams) (*pb.StatSummaryRequest, error)

func BuildTapByResourceRequest

func BuildTapByResourceRequest(params TapRequestParams) (*pb.TapByResourceRequest, error)

func GRPCError

func GRPCError(err error) error

GRPCError generates a gRPC error code, as defined in google.golang.org/grpc/status. If the error is nil or already a gRPC error, return the error. If the error is of type k8s.io/apimachinery/pkg/apis/meta/v1#StatusReason, attempt to map the reason to a gRPC error.

func RenderTapEvent

func RenderTapEvent(event *pb.TapEvent, resource string) string
