Functions

func CallConfigure 

func CallConfigure(instance, conf interface{}) error

CallConfigure will call the Configure method on an observer or monitor with a `conf` object, typed to the correct type. This allows monitors/observers to set the type of the config object to their own config and not have to worry about casting or converting.

func DecodeExtraConfig 

func DecodeExtraConfig(in CustomConfigurable, out interface{}, strict bool) error

DecodeExtraConfig will pull out the OtherConfig values from both ObserverConfig and MonitorConfig and decode them to a struct that is provided in the `out` arg. Whether all fields have to be in 'out' is determined by the 'strict' flag. Any errors decoding will cause `out` to be nil.

func DecodeExtraConfigStrict 

func DecodeExtraConfigStrict(in CustomConfigurable, out interface{}) error

DecodeExtraConfigStrict will pull out any config values from 'in' and put them on the 'out' struct, returning an error if anything in 'in' isn't in 'out'.

func FillInConfigTemplate 

func FillInConfigTemplate(embeddedFieldName string, configTemplate interface{}, conf CustomConfigurable) error

FillInConfigTemplate takes a config template value that a monitor/observer provided and fills it in dynamically from the provided conf

func LoadConfig 

func LoadConfig(ctx context.Context, configPath string) (<-chan *Config, error)

LoadConfig handles loading the main config file and recursively rendering any dynamic values in the config. If watchInterval is 0, the config will be loaded once and sent to the returned channel, after which the channel will be closed. Otherwise, the returned channel will remain open and will be sent any config updates.

func ToString 

func ToString(conf interface{}) string

ToString converts a config struct to a pseudo-yaml text outut. If a struct field has the 'neverLog' tag, its value will be replaced by asterisks, or completely omitted if the tag value is 'omit'.

func ValidateCustomConfig 

func ValidateCustomConfig(conf interface{}) error

ValidateCustomConfig for module-specific config ahead of time for a specific module configuration. This way, the Configure method of modules will be guaranteed to receive valid configuration. The module-specific configuration struct must implement the Validate method that returns a bool.

Types

	WriteThreads int `yaml:"writeThreads" default:"2"`
	// The maximum numbers of values in the queue to be written back to the

Config is the top level config struct for configurations that are common to all platoforms

	Dimensions map[string]string `yaml:"dimensions" default:"{}"`
	// A list of metric names to match against, OR'd together
	MetricNames []string `yaml:"metricNames"`
	// A single metric name to match against
	MetricName string `yaml:"metricName"`
	// (**Only applicable for the top level filters**) Limits this scope of the
	// filter to datapoints from a specific monitor. If specified, any
	// datapoints not from this monitor type will never match against this
	// filter.
	MonitorType string `yaml:"monitorType"`
	// Negates the result of the match so that it matches all datapoints that
	// do NOT match the metric name and dimension values given. This does not
	// negate monitorType, if given.

	// different host/port).
	DiscoveryRule string `yaml:"discoveryRule" json:"discoveryRule"`
	// A set of extra dimensions (key:value pairs) to include on datapoints emitted by the

	// The interval (in seconds) at which to emit datapoints from the
	// monitor(s) created by this configuration.  If not set (or set to 0), the

	// dimensions to be omitted.  You can disable this globally with the
	// `disableHostDimensions` option on the top level of the config.
	DisableHostDimensions bool `yaml:"disableHostDimensions" json:"disableHostDimensions" default:"false"`
	// This can be set to true if you don't want to include the dimensions that

	// important since it acts largely as a proxy or adapter for other metrics.
	DisableEndpointDimensions bool `yaml:"disableEndpointDimensions" json:"disableEndpointDimensions"`
	// OtherConfig is everything else that is custom to a particular monitor
	OtherConfig map[string]interface{} `yaml:",inline" neverLog:"omit"`
