Description

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

Value

Methods

gauge$record()

Update the statistics with the specified amount.

Usage

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

• value: A numeric value. The current absolute value.

• attributes: Additional attributes to add.

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

Value

The gauge object itself, invisibly.

Details

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

A gauge object is created by calling the create_gauge() method of an otel_meter_provider().

You can use the record() method to record the current value.

In R gauge values are represented by doubles.
