OpenTelemetry Histogram Object

Source: R/meter-provider-noop.R
otel_histogram.Rd

otel_meter_provider -> otel_meter -> otel_counter, otel_up_down_counter, otel_histogram, otel_gauge

Value

Not applicable.

Details

Usually you do not need to deal with otel_histogram objects directly. histogram_record() automatically sets up a meter and creates a histogram instrument, as needed.

A histogram object is created by calling the create_histogram() method of an otel_meter_provider().

You can use the record() method to update the statistics with the specified amount.

In R histogram values are represented by doubles.

Methods

histogram$record()

Update the statistics with the specified amount.

Usage

histogram$record(value, attributes = NULL, span_context = NULL, ...)

Arguments

  • value: A numeric value to record.

  • attributes: Additional attributes to add.

  • span_context: Span context. If missing, the active context is used, if any.

Value

The histogram object itself, invisibly.
