Python: Bug in logging to App Insights

[jspoelstra]

agent-framework ==1.0.0b251108

I was using setup_observability() with applicationinsights_connection_string argument. Did not see any logs in App Insights - instead logs ended up on the console.

The issue was a type mismatch bug in the agent_framework library:

• The library checks for isinstance(exporter, LogExporter)
• But Azure Monitor exporters inherit from LogRecordExporter (not LogExporter)
• These are two different classes, so the isinstance check fails
• The library then adds a ConsoleLogExporter as a fallback, causing the verbose JSON output

The fix: Bypass agent_framework.setup_observability() entirely and manually configure OpenTelemetry providers directly, ensuring only Azure Monitor exporters are added (no console exporter):

conn_str = os.getenv("APPLICATIONINSIGHTS_CONNECTION_STRING")

    if conn_str:
        # Create Azure Monitor exporters
        from azure.monitor.opentelemetry.exporter import (
            AzureMonitorLogExporter,
            AzureMonitorTraceExporter,
            AzureMonitorMetricExporter,
        )

        # Set up resource
        resource = Resource.create({"service.name": "ioc-agent-batch"})

        # Configure trace provider
        trace_provider = TracerProvider(resource=resource)
        trace_provider.add_span_processor(BatchSpanProcessor(AzureMonitorTraceExporter(connection_string=conn_str)))
        trace.set_tracer_provider(trace_provider)

        # Configure log provider (MANUALLY - no console exporter!)
        log_provider = LoggerProvider(resource=resource)
        log_provider.add_log_record_processor(BatchLogRecordProcessor(AzureMonitorLogExporter(connection_string=conn_str)))
        _logs.set_logger_provider(log_provider)

        # Configure metrics provider
        metric_reader = PeriodicExportingMetricReader(AzureMonitorMetricExporter(connection_string=conn_str))
        metric_provider = MeterProvider(resource=resource, metric_readers=[metric_reader])
        metrics.set_meter_provider(metric_provider)

        # Attach OpenTelemetry handler to root logger
        root_logger = logging.getLogger()
        root_logger.addHandler(LoggingHandler(logger_provider=log_provider))
    else:
        # No App Insights connection - just use agent_framework defaults
        setup_observability(
            enable_sensitive_data=os.environ.get("ENABLE_SENSITIVE_DATA", "false").lower() == "true",
        )

Thanks for reporting, @jspoelstra we are making some changes (see #2782), and one of those is to make it simpler to setup with things like azure monitor, after this change, you would just call configure_azure_monitor directly, and then with either the env variables or a explicit call to the new enable_instrumentation method you would get this running.
