Module ocp

ocp uses the pdict instead of a ctx variable for tracking context.

Description

The functions fetch the current span context from the pdict and passes it through to the oc_trace function of the same name.

Function Details

add_link/1


      add_link(Link::opencensus:link()) -> boolean()

Add a Link to the list of Links in the current span.

add_time_event/1


      add_time_event(TimeEvent::opencensus:annotation() | opencensus:message_event()) -> boolean()

Add an Annotation or MessageEvent to the list of TimeEvents in the current span.

add_time_event/2


      add_time_event(Timestamp::wts:timestamp(), TimeEvent::opencensus:annotation() | opencensus:message_event()) -> boolean()

current_span_ctx/0


      current_span_ctx() -> maybe(opencensus:span_ctx())

current_tags/0


      current_tags() -> opencensus:tags()

finish_span/0


      finish_span() -> boolean()

Finishes the span in the current pdict context.

put_attribute/2


      put_attribute(Key::unicode:unicode_binary(), Value::opencensus:attribute_value()) -> boolean() | {error, invalid_attribute}

Put an attribute (a key/value pair) in the attribute map of a span. If the attribute already exists it is overwritten with the new value.

put_attributes/1


      put_attributes(NewAttributes::#{unicode:unicode_binary() => opencensus:attribute_value()}) -> boolean()

Merge a map of attributes with the attributes of current span. The new values overwrite the old if any keys are the same.

Set Status of current span.
