Metrics Exporter - In-memory
Status: Stable
In-memory Metrics Exporter is a Push Metric Exporter which accumulates metrics data in the local memory and allows to inspect it (useful for e.g. unit tests).
In-memory Metrics Exporter MUST provide configuration to set
the MetricReader output temporality as a function of
instrument kind. This option MAY be named temporality, and MUST set
temporality to Cumulative for all instrument kinds by default.
In-memory Metrics Exporter MAY provide configuration to set
the MetricReader default aggregation as a function
of instrument kind. This option MAY be named default_aggregation, and MUST use
the default aggregation by default.
If a language provides a mechanism to automatically configure a
MetricReader to pair with the associated
exporter (e.g., using the OTEL_METRICS_EXPORTER environment
variable), by
default the exporter MUST be paired with a periodic exporting
MetricReader.
