Functions

func IsMetadataResourceWithScalarOids

ProfileDefinition is the root profile structure. The ProfileDefinition is currently used in: 1/ SNMP Integration: the profiles are in yaml profiles. Yaml profiles include default datadog profiles and user custom profiles. The serialisation of yaml profiles are defined by the yaml annotation and few custom unmarshaller (see yaml_utils.go). 2/ Datadog backend: the profiles are in json format, they are used to store profiles created via UI. The serialisation of json profiles are defined by the json annotation.

func NewProfileDefinition 

func NewProfileDefinition() *ProfileDefinition

NewProfileDefinition creates a new ProfileDefinition

type ProfileMetricType 

type ProfileMetricType string

ProfileMetricType metric type used to override default type of the metric By default metric type is derived from the type of the SNMP value, for example Counter32/64 -> rate. 

const (
	// ProfileMetricTypeGauge is used to create a gauge metric
	ProfileMetricTypeGauge ProfileMetricType = "gauge"

	// ProfileMetricTypeMonotonicCount is used to create a monotonic_count metric
	ProfileMetricTypeMonotonicCount ProfileMetricType = "monotonic_count"

	// ProfileMetricTypeMonotonicCountAndRate is used to create a monotonic_count and rate metric
	ProfileMetricTypeMonotonicCountAndRate ProfileMetricType = "monotonic_count_and_rate"

	// ProfileMetricTypeRate is used to create a rate metric
	ProfileMetricTypeRate ProfileMetricType = "rate"

	// ProfileMetricTypeFlagStream is used to create metric based on a value that represent flags
	// See details in https://github.com/DataDog/integrations-core/pull/7072
	ProfileMetricTypeFlagStream ProfileMetricType = "flag_stream"

	// ProfileMetricTypeCounter is DEPRECATED
	// `counter` is deprecated in favour of `rate`
	ProfileMetricTypeCounter ProfileMetricType = "counter"

	// `percent` is deprecated in favour of `scale_factor`
	ProfileMetricTypePercent ProfileMetricType = "percent"
)

	ConstantValueOne bool    `yaml:"constant_value_one,omitempty" json:"constant_value_one,omitempty"`

	// `metric_type` is used for force the metric type
	//   When empty, by default, the metric type is derived from SNMP OID value type.
	//   Valid `metric_type` types: `gauge`, `rate`, `monotonic_count`, `monotonic_count_and_rate`
	//   Deprecated types: `counter` (use `rate` instead), percent (use `scale_factor` instead)
	MetricType ProfileMetricType `yaml:"metric_type,omitempty" json:"metric_type,omitempty"`
}

SymbolConfig holds info for a single symbol/oid

type SymbolConfigCompat added in v0.50.0 

type SymbolConfigCompat SymbolConfig

SymbolConfigCompat is used to deserialize string field or SymbolConfig. For OID/Name to Symbol harmonization: When users declare metric tag like: 

metric_tags:
  - OID: 1.2.3
    symbol: aSymbol

this will lead to OID stored as MetricTagConfig.OID and name stored as MetricTagConfig.Symbol.Name When this happens, in ValidateEnrichMetricTags we harmonize by moving MetricTagConfig.OID to MetricTagConfig.Symbol.OID.

func (*SymbolConfigCompat) UnmarshalYAML added in v0.50.0 

func (a *SymbolConfigCompat) UnmarshalYAML(unmarshal func(interface{}) error) error

UnmarshalYAML unmarshalls SymbolConfig
