getMetric

public Optional<io.opentelemetry.sdk.metrics.data.MetricData> getMetric(TelemetryMetricID id)

Get the metric for the given id.

If the metric exists but is the wrong type, an assertionError is thrown.

Parameters:

id - the metric ID

Returns:

the metric data, or an empty Optional

Throws:

AssertionError - if the metric exists but has the wrong type

readLongData
