OpenTelemetry API Bridge
editOpenTelemetry API Bridge
editThe Elastic APM OpenTelemetry bridge allows you to create Elastic APM Transactions
and Spans
,
using the OpenTelemetry API. This allows users to utilize the Elastic APM agent’s
automatic instrumentations, while keeping custom instrumentations vendor neutral.
If a span is created while there is no transaction active, it will result in an
Elastic APM Transaction
. Inner spans
are mapped to Elastic APM Span
.
Getting started
editThe first step in getting started with the OpenTelemetry bridge is to install the opentelemetry
libraries:
pip install elastic-apm[opentelemetry]
Or if you already have installed elastic-apm
:
pip install opentelemetry-api opentelemetry-sdk
Usage
editfrom elasticapm.contrib.opentelemetry import Tracer tracer = Tracer(__name__) with tracer.start_as_current_span("test"): # Do some work
or
from elasticapm.contrib.opentelemetry import trace tracer = trace.get_tracer(__name__) with tracer.start_as_current_span("test"): # Do some work
Tracer
and get_tracer()
accept the following optional arguments:
-
elasticapm_client
: an already instantiated Elastic APM client -
config
: a configuration dictionary, which will be used to instantiate a new Elastic APM client, e.g.{"SERVER_URL": "https://example.org"}
. See configuration for more information.
The Tracer
object mirrors the upstream interface on the
OpenTelemetry Tracer
object.
Caveats
editNot all features of the OpenTelemetry API are supported.
Processors, exporters, metrics, logs, span events, and span links are not supported.
Additionally, due to implementation details, the global context API only works when a span is included in the activated context, and tokens are not used. Instead, the global context works as a stack, and when a context is detached the previously-active context will automatically be activated.
