Make these necessary changes to the app.
pip install azure-monitor-opentelemetryimport logging
from azure.monitor.opentelemetry import configure_azure_monitor
configure_azure_monitor(
logger_name="<your_logger_namespace>"
)
logger = logging.getLogger("<your_logger_namespace>")Note: since we modified the code of the app, it needs to be deployed to take effect.
The App Insights resource has a connection string. Add the connection string as an environment variable of the running app. You can use Azure CLI to query the connection string of the App Insights resource. See [scripts/appinsights.ps1] for what Azure CLI command to execute for querying the connection string.
After getting the connection string, set this environment variable with its value.
"APPLICATIONINSIGHTS_CONNECTION_STRING={your_application_insights_connection_string}"If the app has IaC template such as Bicep or terraform files representing its cloud instance, this environment variable should be added to the IaC template to be applied in each deployment. Otherwise, use Azure CLI to manually apply the environment variable to the cloud instance of the app. See what Azure CLI command to execute for setting this environment variable.
Create a logger that is configured to send telemetry.
logger = logging.getLogger("<your_logger_namespace>")
logger.setLevel(logging.INFO)Then send telemetry events by calling its logging methods.
logger.info("info log")
