agent: observability

When does this happen?

IF POST /api/public/otel/v1/metrics returns 404 when using Langfuse with OpenTelemetry SDK.

How others solved it

THEN Disable metrics export in the OpenTelemetry SDK configuration, or upgrade Langfuse to a version that includes the fix (PR #6408) which accepts metrics silently to reduce warnings.

from opentelemetry.sdk.metrics import MeterProvider
from opentelemetry.sdk.metrics.export import PeriodicExportingMetricReader
# To disable metrics export, do not configure a metric exporter:
# meter_provider = MeterProvider()
# trace.set_meter_provider(meter_provider)
