SDK Implementation Details - Tap Metrics
Metrics logging is specified in the
Singer Spec. The SDK will automatically
emit two types of metrics record_count and http_request_duration.
Customization options:
Developers may optionally add a metrics_log_level config option to their taps,
which will automatically allow this metrics logging to be customized at runtime.
When metrics_log_level is supported, users can then
set one of these values (case insensitive), INFO, DEBUG, NONE, to override the
default logging level for metrics. This can be helpful for REST-type sources which use
make a large number of REST calls can therefor have very noisy metrics.
