O11y (O11y v0.1.0)
A module to help with OpenTelemetry tracing.
Summary
Functions
Sets the given attribute on the current span. If the value is not a valid OTLP type,
it will be converted to a string with inspect
.
Adds the given attributes as a list, map, or struct to the current span. If the value is a maps or struct, it will be converted to a list of key-value pairs. If the struct derives the O11y.SpanAttributes protocol, it will honor the except and only options.
Same as set_attributes/1, but with a prefix for all keys.
Functions
set_attribute(key, value)
Sets the given attribute on the current span. If the value is not a valid OTLP type,
it will be converted to a string with inspect
.
This method does not support structs to maps, regardless of whether the struct implements the O11y.SpanAttributes protocol.
You need to use set_attributes/1
for that.
Example:
iex> set_attribute("key", "value")
set_attributes(values)
Adds the given attributes as a list, map, or struct to the current span. If the value is a maps or struct, it will be converted to a list of key-value pairs. If the struct derives the O11y.SpanAttributes protocol, it will honor the except and only options.
Example:
iex> set_attributes(%{key: "value"})
set_attributes(prefix, values)
Same as set_attributes/1, but with a prefix for all keys.
Example:
iex> set_attributes("my_prefix", %{key: "value"})
