Resource Metrics Cache
target_info metrics and "normal" metrics are a match when they have the same job/instance labels (Please read the specification for more details). But these metrics do not always come in the same Remote-Write request. For this reason, the receiver uses an internal LRU (Least Recently Used) and stateless cache implementation to store resource metrics across requests.
The cleanup is based on a maximum size of 1000 resource metrics, and it will be cleaned when the limit is reached, cleaning the less recently used resource metrics.
This approach has some limitations, for example: - If the process dies or restarts, the cache will be lost. - Some inconsistencies can happen according to the order of the requests and the current cache size. - The limit of 1000 resource metrics is hardcoded and not configurable for now.

Functions ¶
func NewFactory ¶
NewFactory creates a new Prometheus receiver factory.
Types ¶
type Config ¶
type Config struct {
confighttp.ServerConfig `mapstructure:",squash"`
}
Config holds common fields and embedded protocol-specific configurations
type MetricIdentity ¶ added in v0.123.0
type MetricIdentity struct {
ResourceID string
ScopeName string
ScopeVersion string
MetricName string
Unit string
Type writev2.Metadata_MetricType
}
MetricIdentity contains all the components that uniquely identify a metric according to the OpenTelemetry Protocol data model. The definition of the metric uniqueness is based on the following document. Ref: https://opentelemetry.io/docs/specs/otel/metrics/data-model/#opentelemetry-protocol-data-model
func (MetricIdentity) Hash ¶ added in v0.123.0
func (mi MetricIdentity) Hash() uint64
Hash generates a unique hash for the metric identity
