OTEL-044
The OTLP gRPC exporter wants a bare host:port — no URL scheme.
OTEL-045
Without a port, the exporter connects to whatever default it picks.
OTEL-046
The OTLP HTTP exporter needs a full URL (http:// or https://).
OTEL-047
Port 4317 is for gRPC, port 4318 is for HTTP.
OTEL-048
Disabling the sending queue drops data on the first transient failure.
OTEL-049
A queue that holds fewer than 10 items fills up before the first retry completes.
OTEL-050
A very large queue can outlive the memory_limiter and OOM the Collector.
OTEL-051
A single consumer blocks the whole queue on one slow request.
OTEL-052
gzip typically reduces OTLP bandwidth by 70–90% — leaving it off is expensive.
OTEL-053
Infinite retries guarantee unbounded queue growth during an outage.
