[![Gitter chat](https://img.shields.io/gitter/room/Microsoft/azure-monitor-python)](https://gitter.im/Azure/azure-sdk-for-python) | ||
|
||
The exporter for Azure Monitor allows you to export tracing data utilizing the OpenTelemetry SDK and send telemetry data to Azure Monitor for applications written in Python. | ||
|
||
[Source code](https://github.com/Azure/azure-sdk-for-python/tree/master/sdk/monitor/microsoft-opentelemetry-exporter-azuremonitor) | [Package (PyPi)][pypi] | [API reference documentation][api_docs] | [Product documentation][product_docs] | [Samples](https://github.com/Azure/azure-sdk-for-python/tree/master/sdk/monitor/microsoft-opentelemetry-exporter-azuremonitor/samples) | [Changelog](https://github.com/Azure/azure-sdk-for-python/blob/master/sdk/monitor/microsoft-opentelemetry-exporter-azuremonitor/CHANGELOG.md) | ||
|
||
> **NOTE**: This is the preview for the next major version of [`opentelemetry-azure-monitor-python`](https://github.com/microsoft/opentelemetry-azure-monitor-python). | ||
## Getting started | ||
|
||
### Install the package | ||
|
||
Install the Microsoft Opentelemetry exporter for Azure Monitor with [pip][pip]: | ||
|
||
```Bash | ||
pip install microsoft-opentelemetry-exporter-azuremonitor --pre | ||
``` | ||
|
||
### Prerequisites: | ||
To use this package, you must have: | ||
* Azure subscription - [Create a free account][azure_sub] | ||
* Azure Monitor - [How to use application insights][application_insights_namespace] | ||
* Opentelemetry SDK - [Opentelemtry SDK for Python][ot_sdk_python] | ||
* Python 3.5 or later - [Install Python][python] | ||
|
||
### Authenticate the client | ||
|
||
Interaction with Azure monitor exporter starts with an instance of the `AzureMonitorSpanExporter` class. You will need a **connection_string** to instantiate the object. | ||
Please find the samples linked below for demonstration as to how to authenticate using a connection string. | ||
|
||
#### [Create Exporter from connection string][sample_authenticate_client_connstr] | ||
|
||
```Python | ||
from microsoft.opentelemetry.exporter.azuremonitor import AzureMonitorSpanExporter | ||
exporter = AzureMonitorSpanExporter( | ||
connection_string = os.environ["APPLICATIONINSIGHTS_CONNECTION_STRING "] | ||
) | ||
``` | ||
|
||
## Key concepts | ||
|
||
Some of the key concepts for the Azure monitor exporter include: | ||
|
||
* [Opentelemetry][opentelemtry_spec]: Opentelemetry is a set of libraries used to collect and export telemetry data (metrics, logs, and traces) for analysis in order to understand your software's performance and behavior. | ||
|
||
* [Instrumentation][instrumentation_library]: The ability to call the opentelemetry API directly by any application is facilitated by instrumentaton. A library that enables OpenTelemetry observability for another library is called an Instrumentation Library. | ||
|
||
* [Trace][trace_concept]: Trace refers to distributed tracing. It can be thought of as a directed acyclic graph (DAG) of Spans, where the edges between Spans are defined as parent/child relationship. | ||
|
||
* [Tracer Provider][tracer_provider]: Provides a `Tracer` for use by the given instrumentation library. | ||
|
||
* [Span Processor][span_processor]: A span processor allows hooks for SDK's `Span` start and end method invocations. Follow the link for more information. | ||
|
||
* [Sampling][sampler_ref]: Sampling is a mechanism to control the noise and overhead introduced by OpenTelemetry by reducing the number of samples of traces collected and sent to the backend. | ||
|
||
* [AzureMonitorSpanExporter][client_reference]: This is the class that is initialized to send tracing related telemetry to Azure Monitor. | ||
|
||
* [Exporter Options][exporter_options]: Options to configure Azure exporters. Includes connection_string, instrumentation_key, proxies, timeout etc. | ||
|
||
For more information about these resources, see [What is Azure Monitor?][product_docs]. | ||
|
||
## Examples | ||
|
||
The following sections provide several code snippets covering some of the most common tasks, including: | ||
|
||
* [Exporting a custom span](#export-hello-world-trace) | ||
* [Modifying spans](#modifying-traces) | ||
* [Using an instrumentation to track a library](#instrumentation-with-requests-library) | ||
|
||
|
||
### Export Hello World Trace | ||
|
||
```Python | ||
import os | ||
from opentelemetry import trace | ||
from opentelemetry.sdk.trace import TracerProvider | ||
from opentelemetry.sdk.trace.export import BatchExportSpanProcessor | ||
from microsoft.opentelemetry.exporter.azuremonitor import AzureMonitorSpanExporter | ||
|
||
exporter = AzureMonitorSpanExporter( | ||
connection_string = os.environ["APPLICATIONINSIGHTS_CONNECTION_STRING "] | ||
) | ||
|
||
trace.set_tracer_provider(TracerProvider()) | ||
tracer = trace.get_tracer(__name__) | ||
span_processor = BatchExportSpanProcessor(exporter) | ||
trace.get_tracer_provider().add_span_processor(span_processor) | ||
|
||
with tracer.start_as_current_span("hello"): | ||
print("Hello, World!") | ||
``` | ||
|
||
### Modifying Traces | ||
|
||
* You can pass a callback function to the exporter to process telemetry before it is exported. | ||
* Your callback function can return False if you do not want this envelope exported. | ||
* Your callback function must accept an envelope data type as its parameter. | ||
* You can see the schema for Azure Monitor data types in the envelopes here. | ||
* The AzureMonitorSpanExporter handles Data data types. | ||
|
||
```Python | ||
from microsoft.opentelemetry.exporter.azuremonitor import AzureMonitorSpanExporter | ||
from opentelemetry import trace | ||
from opentelemetry.sdk.trace import TracerProvider | ||
from opentelemetry.sdk.trace.export import BatchExportSpanProcessor | ||
|
||
# Callback function to add os_type: linux to span properties | ||
def callback_function(envelope): | ||
envelope.data.baseData.properties['os_type'] = 'linux' | ||
return True | ||
|
||
exporter = AzureMonitorSpanExporter( | ||
connection_string='InstrumentationKey=<your-ikey-here>' | ||
) | ||
# This line will modify telemetry | ||
exporter.add_telemetry_processor(callback_function) | ||
|
||
trace.set_tracer_provider(TracerProvider()) | ||
tracer = trace.get_tracer(__name__) | ||
span_processor = BatchExportSpanProcessor(exporter) | ||
trace.get_tracer_provider().add_span_processor(span_processor) | ||
|
||
with tracer.start_as_current_span('hello'): | ||
print('Hello World!') | ||
``` | ||
|
||
### Instrumentation with requests library | ||
|
||
OpenTelemetry also supports several instrumentations which allows to instrument with third party libraries. | ||
|
||
This example shows how to instrument with the [requests](https://pypi.org/project/requests/) library. | ||
|
||
* Install the requests integration package using pip install opentelemetry-instrumentation-requests. | ||
|
||
```Python | ||
import os | ||
import requests | ||
from opentelemetry import trace | ||
from opentelemetry.instrumentation.requests import RequestsInstrumentor | ||
from opentelemetry.sdk.trace import TracerProvider | ||
from opentelemetry.sdk.trace.export import BatchExportSpanProcessor | ||
|
||
from microsoft.opentelemetry.exporter.azuremonitor import AzureMonitorSpanExporter | ||
|
||
trace.set_tracer_provider(TracerProvider()) | ||
tracer = trace.get_tracer(__name__) | ||
|
||
# This line causes your calls made with the requests library to be tracked. | ||
RequestsInstrumentor().instrument() | ||
span_processor = BatchExportSpanProcessor( | ||
AzureMonitorSpanExporter( | ||
connection_string = os.environ["APPLICATIONINSIGHTS_CONNECTION_STRING "] | ||
) | ||
) | ||
trace.get_tracer_provider().add_span_processor(span_processor) | ||
|
||
RequestsInstrumentor().instrument() | ||
|
||
# This request will be traced | ||
response = requests.get(url="https://azure.microsoft.com/") | ||
``` | ||
|
||
## Troubleshooting | ||
|
||
The exporter raises exceptions defined in [Azure Core](https://github.com/Azure/azure-sdk-for-python/blob/master/sdk/core/azure-core/README.md#azure-core-library-exceptions). | ||
|
||
## Next steps | ||
|
||
### More sample code | ||
|
||
Please find further examples in the [samples](https://github.com/Azure/azure-sdk-for-python/tree/master/sdk/monitor/microsoft-opentelemetry-exporter-azuremonitor/samples) directory demonstrating common scenarios. | ||
|
||
