Does span_frames_min_duration config apply?

Elastic Observability APM
1

We attempted to increase the value of the span_frames_min_duration , but it appears the agent is not honouring the configuration—we're still receiving spans shorter than the configured threshold.

Note: We're setting the value exclusively via environment variables.
ELASTIC_APM_SPAN_FRAMES_MIN_DURATION

This configuration does not exist, maybe what you meant to use is span_min_duration ?

The agent logs the effective configuration in the first few lines of the agent log, you should check that the values that you have configured are properly set by checking if they are visible in those log lines, unsupported configurations are silently ignored.
