Metrics are pushed every 60s and Alloy's OTLP receiver closes connections idle for 1m, while the exporters keep them for 90s. A push could reuse a connection the collector was closing and fail with EOF or connection reset; the data was dropped (no retry for a POST or for transport errors). In prod that was ~3 failed metric pushes per pod per hour, plus occasional trace batches.
Both exporters now use an HTTP client that closes idle connections after 30s. A custom client makes the exporters ignore the OTLP timeout and certificate env vars; none are set.
