# Microsoft OpenTelemetry exporter for Azure Monitor
The exporter for Azure Monitor allows Python applications to export data from the OpenTelemetry SDK to Azure Monitor. The exporter is intended for users who require advanced configuration or have more complicated telemetry needs that require all of distributed tracing, logging and metrics. If you have simpler configuration requirements, we recommend using the [Azure Monitor OpenTelemetry Distro](https://learn.microsoft.com/azure/azure-monitor/app/opentelemetry-enable?tabs=python) instead for a simpler one-line setup.
Prior to using this SDK, please read and understand [Data Collection Basics](https://learn.microsoft.com/azure/azure-monitor/app/opentelemetry-overview?tabs=python), especially the section on [telemetry types](https://learn.microsoft.com/azure/azure-monitor/app/opentelemetry-overview?tabs=python#telemetry-types). OpenTelemetry terminology differs from Application Insights terminology so it is important to understand the way the telemetry types map to each other.

## Getting started
### Install the package
Install the Microsoft OpenTelemetry exporter for Azure Monitor with [pip][pip]:
```Bash
pip install azure-monitor-opentelemetry-exporter --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 - [OpenTelemetry SDK for Python][ot_sdk_python]
* Python 3.8 or later - [Install Python][python]
### Instantiate the client
Interaction with Azure monitor exporter starts with an instance of the `AzureMonitorTraceExporter` class for distributed tracing, `AzureMonitorLogExporter` for logging and `AzureMonitorMetricExporter` for metrics. You will need a **connection_string** to instantiate the object.
Please find the samples linked below for demonstration as to how to construct the exporter using a connection string.
#### Logging (experimental)
NOTE: The logging signal for the `AzureMonitorLogExporter` is currently in an EXPERIMENTAL state. Possible breaking changes may ensue in the future.
```python
from azure.monitor.opentelemetry.exporter import AzureMonitorLogExporter
exporter = AzureMonitorLogExporter(
connection_string=os.environ["APPLICATIONINSIGHTS_CONNECTION_STRING"]
)
```
#### Metrics
```python
from azure.monitor.opentelemetry.exporter import AzureMonitorMetricExporter
exporter = AzureMonitorMetricExporter(
connection_string=os.environ["APPLICATIONINSIGHTS_CONNECTION_STRING"]
)
```
#### Tracing
```python
from azure.monitor.opentelemetry.exporter import AzureMonitorTraceExporter
exporter = AzureMonitorTraceExporter(
connection_string=os.environ["APPLICATIONINSIGHTS_CONNECTION_STRING"]
)
```
You can also instantiate the exporter directly via the constructor. In this case, the connection string will be automatically populated from the `APPLICATIONINSIGHTS_CONNECTION_STRING` environment variable.
```python
from azure.monitor.opentelemetry.exporter import AzureMonitorLogExporter
exporter = AzureMonitorLogExporter()
```
```python
from azure.monitor.opentelemetry.exporter import AzureMonitorMetricExporter
exporter = AzureMonitorMetricExporter()
```
```python
from azure.monitor.opentelemetry.exporter import AzureMonitorTraceExporter
exporter = AzureMonitorTraceExporter()
```
## Key concepts
Some of the key concepts for the Azure monitor exporter include:
* [OpenTelemetry][opentelemetry_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 instrumentation. A library that enables OpenTelemetry observability for another library is called an instrumentation Library.
* [Log][log_concept]: Log refers to capturing of logging, exception and events.
* [LogRecord][log_record]: Represents a log record emitted from a supported logging library.
* [Logger][logger]: Converts a `LogRecord` into a readable `LogData`, and will be pushed through the SDK to be exported.
* [Logger Provider][logger_provider]: Provides a `Logger` for the given instrumentation library.
* [LogRecordProcessor][log_record_processor]: Interface to hook the log record emitting action.
* [LoggingHandler][logging_handler]: A handler class which writes logging records in OpenTelemetry format from the standard Python `logging` library.
* [AzureMonitorLogExporter][log_reference]: This is the class that is initialized to send logging related telemetry to Azure Monitor.
* [Metric][metric_concept]: `Metric` refers to recording raw measurements with predefined aggregation and sets of attributes for a period in time.
* [Measurement][measurement]: Represents a data point recorded at a point in time.
* [Instrument][instrument]: Instruments are used to report `Measurement`s.
* [Meter][meter]: The `Meter` is responsible for creating `Instruments`.
* [Meter Provider][meter_provider]: Provides a `Meter` for the given instrumentation library.
* [Metric Reader][metric_reader]: An SDK implementation object that provides the common configurable aspects of the OpenTelemetry Metrics SDK such as collection, flushing and shutdown.
* [AzureMonitorMetricExporter][metric_reference]: This is the class that is initialized to send metric related telemetry to Azure Monitor.
* [Trace][trace_concept]: Trace refers to distributed tracing. A distributed trace is a set of events, triggered as a result of a single logical operation, consolidated across various components of an application. In particular, a Trace can be thought of as a directed acyclic graph (DAG) of Spans, where the edges between Spans are defined as parent/child relationship.
* [Span][span]: Represents a single operation within a `Trace`. Can be nested to form a trace tree. Each trace contains a root span, which typically describes the entire operation and, optionally, one ore more sub-spans for its sub-operations.
* [Tracer][tracer]: Responsible for creating `Span`s.
* [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.
* [AzureMonitorTraceExporter][trace_reference]: This is the class that is initialized to send tracing related telemetry to Azure Monitor.
* [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.
* ApplicationInsightsSampler: Application Insights specific sampler used for consistent sampling across Application Insights SDKs and OpenTelemetry-based SDKs sending data to Application Insights. This sampler MUST be used whenever `AzureMonitorTraceExporter` is used.
For more information about these resources, see [What is Azure Monitor?][product_docs].
## Configuration
All configuration options can be passed through the constructors of exporters through `kwargs`. Below is a list of configurable options.
* `connection_string`: The connection string used for your Application Insights resource.
* `disable_offline_storage`: Boolean value to determine whether to disable storing failed telemetry records for retry. Defaults to `False`.
* `storage_directory`: Storage directory in which to store retry files. Defaults to `<tempfile.gettempdir()>/Microsoft/AzureMonitor/opentelemetry-python-<your-instrumentation-key>`.
* `credential`: Token credential, such as ManagedIdentityCredential or ClientSecretCredential, used for [Azure Active Directory (AAD) authentication][aad_for_ai_docs]. Defaults to None. See [samples][exporter_samples] for examples.

trace.get_tracer_provider().add_span_processor(span_processor)
for i in range(100):
# Approximately 25% of these spans should be sampled out
with tracer.start_as_current_span("hello"):
print("Hello, World!")
```
## Flush/shutdown behavior
For all applications set up with OpenTelemetry SDK and Azure Monitor exporters, telemetry is flushed automatically upon application exit. Note that this does not include when application ends abruptly or crashes due to uncaught exception.
## Troubleshooting
The exporter raises exceptions defined in [Azure Core](https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/core/azure-core/README.md#azure-core-library-exceptions).
## Next steps
### More sample code
Please find further examples in the [samples][exporter_samples] directory demonstrating common scenarios.

"description": "# Microsoft OpenTelemetry exporter for Azure Monitor\n\nThe exporter for Azure Monitor allows Python applications to export data from the OpenTelemetry SDK to Azure Monitor. The exporter is intended for users who require advanced configuration or have more complicated telemetry needs that require all of distributed tracing, logging and metrics. If you have simpler configuration requirements, we recommend using the [Azure Monitor OpenTelemetry Distro](https://learn.microsoft.com/azure/azure-monitor/app/opentelemetry-enable?tabs=python) instead for a simpler one-line setup.\n\nPrior to using this SDK, please read and understand [Data Collection Basics](https://learn.microsoft.com/azure/azure-monitor/app/opentelemetry-overview?tabs=python), especially the section on [telemetry types](https://learn.microsoft.com/azure/azure-monitor/app/opentelemetry-overview?tabs=python#telemetry-types). OpenTelemetry terminology differs from Application Insights terminology so it is important to understand the way the telemetry types map to each other.\n\n[Source code](https://github.com/Azure/azure-sdk-for-python/tree/main/sdk/monitor/azure-monitor-opentelemetry-exporter) | [Package (PyPi)][pypi] | [API reference documentation][api_docs] | [Product documentation][product_docs] | [Samples][exporter_samples] | [Changelog](https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/monitor/azure-monitor-opentelemetry-exporter/CHANGELOG.md)\n\n## Getting started\n\n### Install the package\n\nInstall the Microsoft OpenTelemetry exporter for Azure Monitor with [pip][pip]:\n\n```Bash\npip install azure-monitor-opentelemetry-exporter --pre\n```\n\n### Prerequisites\n\nTo use this package, you must have:\n\n* Azure subscription - [Create a free account][azure_sub]\n* Azure Monitor - [How to use application insights][application_insights_namespace]\n* OpenTelemetry SDK - [OpenTelemetry SDK for Python][ot_sdk_python]\n* Python 3.8 or later - [Install Python][python]\n\n### Instantiate the client\n\nInteraction with Azure monitor exporter starts with an instance of the `AzureMonitorTraceExporter` class for distributed tracing, `AzureMonitorLogExporter` for logging and `AzureMonitorMetricExporter` for metrics. You will need a **connection_string** to instantiate the object.\nPlease find the samples linked below for demonstration as to how to construct the exporter using a connection string.\n\n#### Logging (experimental)\n\nNOTE: The logging signal for the `AzureMonitorLogExporter` is currently in an EXPERIMENTAL state. Possible breaking changes may ensue in the future.\n\n```python\nfrom azure.monitor.opentelemetry.exporter import AzureMonitorLogExporter\nexporter = AzureMonitorLogExporter(\n connection_string=os.environ[\"APPLICATIONINSIGHTS_CONNECTION_STRING\"]\n)\n```\n\n#### Metrics\n\n```python\nfrom azure.monitor.opentelemetry.exporter import AzureMonitorMetricExporter\nexporter = AzureMonitorMetricExporter(\n connection_string=os.environ[\"APPLICATIONINSIGHTS_CONNECTION_STRING\"]\n)\n```\n\n#### Tracing\n\n```python\nfrom azure.monitor.opentelemetry.exporter import AzureMonitorTraceExporter\nexporter = AzureMonitorTraceExporter(\n connection_string=os.environ[\"APPLICATIONINSIGHTS_CONNECTION_STRING\"]\n)\n```\n\nYou can also instantiate the exporter directly via the constructor. In this case, the connection string will be automatically populated from the `APPLICATIONINSIGHTS_CONNECTION_STRING` environment variable.\n\n```python\nfrom azure.monitor.opentelemetry.exporter import AzureMonitorLogExporter\nexporter = AzureMonitorLogExporter()\n```\n\n```python\nfrom azure.monitor.opentelemetry.exporter import AzureMonitorMetricExporter\nexporter = AzureMonitorMetricExporter()\n```\n\n```python\nfrom azure.monitor.opentelemetry.exporter import AzureMonitorTraceExporter\nexporter = AzureMonitorTraceExporter()\n```\n\n## Key concepts\n\nSome of the key concepts for the Azure monitor exporter include:\n\n* [OpenTelemetry][opentelemetry_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.\n\n* [Instrumentation][instrumentation_library]: The ability to call the OpenTelemetry API directly by any application is facilitated by instrumentation. A library that enables OpenTelemetry observability for another library is called an instrumentation Library.\n\n* [Log][log_concept]: Log refers to capturing of logging, exception and events.\n\n* [LogRecord][log_record]: Represents a log record emitted from a supported logging library.\n\n* [Logger][logger]: Converts a `LogRecord` into a readable `LogData`, and will be pushed through the SDK to be exported.\n\n* [Logger Provider][logger_provider]: Provides a `Logger` for the given instrumentation library.\n\n* [LogRecordProcessor][log_record_processor]: Interface to hook the log record emitting action.\n\n* [LoggingHandler][logging_handler]: A handler class which writes logging records in OpenTelemetry format from the standard Python `logging` library.\n\n* [AzureMonitorLogExporter][log_reference]: This is the class that is initialized to send logging related telemetry to Azure Monitor.\n\n* [Metric][metric_concept]: `Metric` refers to recording raw measurements with predefined aggregation and sets of attributes for a period in time.\n\n* [Measurement][measurement]: Represents a data point recorded at a point in time.\n\n* [Instrument][instrument]: Instruments are used to report `Measurement`s.\n\n* [Meter][meter]: The `Meter` is responsible for creating `Instruments`.\n\n* [Meter Provider][meter_provider]: Provides a `Meter` for the given instrumentation library.\n\n* [Metric Reader][metric_reader]: An SDK implementation object that provides the common configurable aspects of the OpenTelemetry Metrics SDK such as collection, flushing and shutdown.\n\n* [AzureMonitorMetricExporter][metric_reference]: This is the class that is initialized to send metric related telemetry to Azure Monitor.\n\n* [Trace][trace_concept]: Trace refers to distributed tracing. A distributed trace is a set of events, triggered as a result of a single logical operation, consolidated across various components of an application. In particular, a Trace can be thought of as a directed acyclic graph (DAG) of Spans, where the edges between Spans are defined as parent/child relationship.\n\n* [Span][span]: Represents a single operation within a `Trace`. Can be nested to form a trace tree. Each trace contains a root span, which typically describes the entire operation and, optionally, one ore more sub-spans for its sub-operations.\n\n* [Tracer][tracer]: Responsible for creating `Span`s.\n\n* [Tracer Provider][tracer_provider]: Provides a `Tracer` for use by the given instrumentation library.\n\n* [Span Processor][span_processor]: A span processor allows hooks for SDK's `Span` start and end method invocations. Follow the link for more information.\n\n* [AzureMonitorTraceExporter][trace_reference]: This is the class that is initialized to send tracing related telemetry to Azure Monitor.\n\n* [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.\n\n* ApplicationInsightsSampler: Application Insights specific sampler used for consistent sampling across Application Insights SDKs and OpenTelemetry-based SDKs sending data to Application Insights. This sampler MUST be used whenever `AzureMonitorTraceExporter` is used.\n\nFor more information about these resources, see [What is Azure Monitor?][product_docs].\n\n## Configuration\n\nAll configuration options can be passed through the constructors of exporters through `kwargs`. Below is a list of configurable options.\n\n* `connection_string`: The connection string used for your Application Insights resource.\n* `disable_offline_storage`: Boolean value to determine whether to disable storing failed telemetry records for retry. Defaults to `False`.\n* `storage_directory`: Storage directory in which to store retry files. Defaults to `<tempfile.gettempdir()>/Microsoft/AzureMonitor/opentelemetry-python-<your-instrumentation-key>`.\n* `credential`: Token credential, such as ManagedIdentityCredential or ClientSecretCredential, used for [Azure Active Directory (AAD) authentication][aad_for_ai_docs]. Defaults to None. See [samples][exporter_samples] for examples.\n\n## Examples\n\n### Logging (experimental)\n\nNOTE: The logging signal for the `AzureMonitorLogExporter` is currently in an EXPERIMENTAL state. Possible breaking changes may ensue in the future.\n\nThe following sections provide several code snippets covering some of the most common tasks, including:\n\n* [Exporting a log record](#export-hello-world-log)\n* [Exporting correlated log record](#export-correlated-log)\n* [Exporting log record with custom properties](#export-custom-properties-log)\n* [Exporting an exceptions log record](#export-exceptions-log)\n\nReview the [OpenTelemetry Logging SDK][ot_logging_sdk] to learn how to use OpenTelemetry components to collect logs.\n\n#### Export Hello World Log\n\n```python\n\"\"\"\nAn example to show an application using Opentelemetry logging sdk.

ZeroDivisionError:\n logger.error(\"Error: Division by zero\", stack_info=True, exc_info=True)\n```\n\n### Metrics\n\nThe following sections provide several code snippets covering some of the most common tasks, including:\n\n* [Using different metric instruments](#metric-instrument-usage)\n* [Customizing outputted metrics with views](#metric-custom-views)\n* [Recording instruments with attributes](#metric-record-attributes)\n\nReview the [OpenTelemetry Metrics SDK][ot_metrics_sdk] to learn how to use OpenTelemetry components to collect metrics.\n\n#### Metric instrument usage\n\n```python\n\"\"\"\nAn example to show an application using all instruments in the OpenTelemetry SDK. Metrics created\nand recorded using the sdk are tracked and telemetry is exported to application insights with the\nAzureMonitorMetricsExporter.\n\"\"\"\nimport os\nfrom typing import Iterable\n\nfrom opentelemetry import metrics\nfrom opentelemetry.metrics import CallbackOptions, Observation\nfrom opentelemetry.sdk.metrics import MeterProvider\nfrom opentelemetry.sdk.metrics.export import PeriodicExportingMetricReader\n\nfrom azure.monitor.opentelemetry.exporter import AzureMonitorMetricExporter\n\nexporter = AzureMonitorMetricExporter(\n connection_string=os.environ[\"APPLICATIONINSIGHTS_CONNECTION_STRING\"]\n)\nreader = PeriodicExportingMetricReader(exporter, export_interval_millis=5000)\nmetrics.set_meter_provider(MeterProvider(metric_readers=[reader]))\n\n# Create a namespaced meter\nmeter = metrics.get_meter_provider().get_meter(\"sample\")\n\n# Callback functions for observable instruments\ndef observable_counter_func(options: CallbackOptions) -> Iterable[Observation]:\n yield Observation(1, {})\n\n\ndef observable_up_down_counter_func(\n options: CallbackOptions,\n) -> Iterable[Observation]:\n yield Observation(-10, {})\n\n\ndef observable_gauge_func(options: CallbackOptions) -> Iterable[Observation]:\n yield Observation(9, {})\n\n# Counter\ncounter = meter.create_counter(\"counter\")\ncounter.add(1)\n\n# Async Counter\nobservable_counter = meter.create_observable_counter(\n \"observable_counter\", [observable_counter_func]\n)\n\n# UpDownCounter\nup_down_counter = meter.create_up_down_counter(\"up_down_counter\")\nup_down_counter.add(1)\nup_down_counter.add(-5)\n\n# Async UpDownCounter\nobservable_up_down_counter = meter.create_observable_up_down_counter(\n \"observable_up_down_counter\", [observable_up_down_counter_func]\n)\n\n# Histogram\nhistogram = meter.create_histogram(\"histogram\")\nhistogram.record(99.9)\n\n# Async Gauge\ngauge = meter.create_observable_gauge(\"gauge\", [observable_gauge_func])\n\n# Upon application exit, one last collection is made and telemetry records are\n# flushed automatically. # If you would like to flush records manually yourself,\n# you can call force_flush()\nmeter_provider.force_flush()\n```\n\n#### Metric custom views\n\n```python\n\"\"\"\nThis example shows how to customize the metrics that are output by the SDK using Views. Metrics created\nand recorded using the sdk are tracked and telemetry is exported to application insights with the\nAzureMonitorMetricsExporter.\n\"\"\"\nimport os\n\nfrom opentelemetry import metrics\nfrom opentelemetry.sdk.metrics import Counter, MeterProvider\nfrom opentelemetry.sdk.metrics.export import PeriodicExportingMetricReader\nfrom opentelemetry.sdk.metrics.view import View\n\nfrom azure.monitor.opentelemetry.exporter import AzureMonitorMetricExporter\n\nexporter = AzureMonitorMetricExporter.from_connection_string(\n os.environ[\"APPLICATIONINSIGHTS_CONNECTION_STRING\"]\n)\n# Create a view matching the counter instrument `my.counter`\n# and configure the new name `my.counter.total` for the result metrics stream\nchange_metric_name_view = View(\n instrument_type=Counter,\n instrument_name=\"my.counter\",\n name=\"my.counter.total\",\n)\n\nreader = PeriodicExportingMetricReader(exporter, export_interval_millis=5000)\nprovider = MeterProvider(\n metric_readers=[\n reader,\n ],\n views=[\n change_metric_name_view,\n ],\n)\nmetrics.set_meter_provider(provider)\n\nmeter = metrics.get_meter_provider().get_meter(\"view-name-change\")\nmy_counter = meter.create_counter(\"my.counter\")\nmy_counter.add(100)\n\n```\n\nMore examples with the metrics `Views` SDK can be found [here](https://github.com/open-telemetry/opentelemetry-python/tree/main/docs/examples/metrics/views).\n\n#### Metric record attributes\n\n```python\n\"\"\"\nAn example to show an application using different attributes with instruments in the OpenTelemetry SDK.\nMetrics created and recorded using the sdk are tracked and telemetry is exported to application insights\nwith the AzureMonitorMetricsExporter.\n\"\"\"\nimport os\n\nfrom opentelemetry import metrics\nfrom opentelemetry.sdk.metrics import MeterProvider\nfrom opentelemetry.sdk.metrics.export import PeriodicExportingMetricReader\n\nfrom azure.monitor.opentelemetry.exporter import AzureMonitorMetricExporter\n\nexporter = AzureMonitorMetricExporter.from_connection_string(\n os.environ[\"APPLICATIONINSIGHTS_CONNECTION_STRING\"]\n)\nreader = PeriodicExportingMetricReader(exporter, export_interval_millis=5000)\nmetrics.set_meter_provider(MeterProvider(metric_readers=[reader]))\n\nattribute_set1 = {\n \"key1\": \"val1\"\n}\nattribute_set2 = {\n \"key2\": \"val2\"\n}\nlarge_attribute_set = {}\nfor i in range(20):\n key = \"key{}\".format(i)\n val = \"val{}\".format(i)\n large_attribute_set[key] = val\n\nmeter = metrics.get_meter_provider().get_meter(\"sample\")\n\n# Counter\ncounter = meter.create_counter(\"attr1_counter\")\ncounter.add(1, attribute_set1)\n\n# Counter2\ncounter2 = meter.create_counter(\"attr2_counter\")\ncounter2.add(10, attribute_set1)\ncounter2.add(30, attribute_set2)\n\n# Counter3\ncounter3 = meter.create_counter(\"large_attr_counter\")\ncounter3.add(100, attribute_set1)\ncounter3.add(200, large_attribute_set)\n\n```\n\n### Tracing\n\nThe following sections provide several code snippets covering some of the most common tasks, including:\n\n* [Exporting a custom span](#export-hello-world-trace)\n* [Using an instrumentation to track a library](#instrumentation-with-requests-library)\n* [Enabling sampling to limit the amount of telemetry sent](#enabling-sampling)\n\nReview the [OpenTelemetry Tracing SDK][ot_tracing_sdk] to learn how to use OpenTelemetry components to collect logs.\n\n#### Export Hello World Trace\n\n```python\n\"\"\"\nAn example to show an application using Opentelemetry tracing api and sdk.

In order to enable correct sampling in Application Insights, use the `ApplicationInsightsSampler` as shown below.\n\n```python\n\"\"\"\nAn example to show an application using the ApplicationInsightsSampler to enable sampling for your telemetry.\nSpecify a sampling rate for the sampler to limit the amount of telemetry records you receive. Custom dependencies\n are tracked via spans and telemetry is exported to application insights with the AzureMonitorTraceExporter.\n\"\"\"\nimport os\nfrom opentelemetry import trace\nfrom opentelemetry.sdk.trace import TracerProvider\nfrom opentelemetry.sdk.trace.export import BatchSpanProcessor\nfrom azure.monitor.opentelemetry.exporter import (\n ApplicationInsightsSampler,\n AzureMonitorTraceExporter,\n)\n\n# Sampler expects a sample rate of between 0 and 1 inclusive\n# A rate of 0.75 means approximately 75% of your telemetry will be sent\nsampler = ApplicationInsightsSampler(0.75)\ntrace.set_tracer_provider(TracerProvider(sampler=sampler))\ntracer = trace.get_tracer(__name__)\nexporter = AzureMonitorTraceExporter(\n connection_string=os.environ[\"APPLICATIONINSIGHTS_CONNECTION_STRING\"]\n)\nspan_processor = BatchSpanProcessor(exporter)\ntrace.get_tracer_provider().add_span_processor(span_processor)\n\nfor i in range(100):\n # Approximately 25% of these spans should be sampled out\n with tracer.start_as_current_span(\"hello\"):\n print(\"Hello, World!\")\n```\n\n## Flush/shutdown behavior\n\nFor all applications set up with OpenTelemetry SDK and Azure Monitor exporters, telemetry is flushed automatically upon application exit. Note that this does not include when application ends abruptly or crashes due to uncaught exception.\n\n## Troubleshooting\n\nThe exporter raises exceptions defined in [Azure Core](https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/core/azure-core/README.md#azure-core-library-exceptions).\n\n## Next steps\n\n### More sample code\n\nPlease find further examples in the [samples][exporter_samples] directory demonstrating common scenarios.\n\n### Additional documentation\n\nFor more extensive documentation on the Azure Monitor service, see the [Azure Monitor documentation][product_docs] on docs.microsoft.com.\n\nFor detailed overview of OpenTelemetry, visit their [overview](https://github.com/open-telemetry/opentelemetry-specification/blob/master/specification/overview.md) page.\n\nFor the official OpenTelemetry Python documentation and how to enable other telemetry scenarios, visit the official OpenTelemetry [website](https://opentelemetry.io/docs/instrumentation/python/).\n\nFor more information on the Azure Monitor OpenTelemetry Distro, which is a bundle of useful, pre-assembled components (one of them being this current package) that enable telemetry scenarios with Azure Monitor, visit the [README](https://github.com/Azure/azure-sdk-for-python/tree/main/sdk/monitor/azure-monitor-opentelemetry).\n\n## Contributing\n\nThis project welcomes contributions and suggestions.
