The various modules that make up Mimir.

Functions

func DisableSignalHandling

func DisableSignalHandling(config *server.Config)

DisableSignalHandling puts a dummy signal handler

func InheritCommonFlagValues

func InheritCommonFlagValues(log log.Logger, fs *flag.FlagSet, common CommonConfig, inheriters ...CommonConfigInheriter) error

InheritCommonFlagValues will inherit the values of the provided common flags to all the inheriters.

func NewRuntimeManager

func NewRuntimeManager(cfg *Config, name string, reg prometheus.Registerer, logger log.Logger) (*runtimeconfig.Manager, error)

NewRuntimeManager returns a runtimeconfig.Manager, a services.Service that must be explicitly started to perform any work. cfg is initialized as necessary, before being passed to runtimeconfig.New.

func NewServerService

func NewServerService(serv *server.Server, servicesToWaitFor func() []services.Service) services.Service

NewServerService constructs service from Server component. servicesToWaitFor is called when server is stopping, and should return all services that need to terminate before server actually stops. N.B.: this function is NOT Mimir specific, please let's keep it that way. Passed server should not react on signals. Early return from Run function is considered to be an error.

func ThanosTracerStreamInterceptor

func ThanosTracerStreamInterceptor(srv interface{}, ss grpc.ServerStream, _ *grpc.StreamServerInfo, handler grpc.StreamHandler) error

ThanosTracerStreamInterceptor injects the opentracing global tracer into the context in order to get it picked up by Thanos components.

func ThanosTracerUnaryInterceptor

func ThanosTracerUnaryInterceptor(ctx context.Context, req interface{}, _ *grpc.UnaryServerInfo, handler grpc.UnaryHandler) (interface{}, error)

ThanosTracerUnaryInterceptor injects the opentracing global tracer into the context in order to get it picked up by Thanos components.

func UnmarshalCommonYAML

func UnmarshalCommonYAML(value *yaml.Node, inheriters ...CommonConfigInheriter) error

UnmarshalCommonYAML provides the implementation for UnmarshalYAML functions to unmarshal the CommonConfig. A list of CommonConfig inheriters can be provided

Types

Config is the root config for Mimir.

func (*Config) CommonConfigInheritance

func (c *Config) CommonConfigInheritance() CommonConfigInheritance

func (*Config) RegisterFlags

func (c *Config) RegisterFlags(f *flag.FlagSet, logger log.Logger)

RegisterFlags registers flags.

func (*Config) Validate

func (c *Config) Validate(log log.Logger) error

Validate the mimir config and return an error if the validation doesn't pass

func (*Config) ValidateLimits

func (c *Config) ValidateLimits(limits validation.Limits) error

ValidateLimits validates the runtime limits that can be set for each tenant against static configs

type ConfigWithCommon

type ConfigWithCommon Config

ConfigWithCommon should be passed to yaml.Unmarshal to properly unmarshal Common values. We don't implement UnmarshalYAML on Config itself because that would disallow inlining it in other configs.

func (*ConfigWithCommon) UnmarshalYAML

func (c *ConfigWithCommon) UnmarshalYAML(value *yaml.Node) error
