sampling¶

Sampling is the practice of discarding some traces or spans to reduce the amount of data that needs to be stored and analyzed. Sampling is a tradeoff between cost and data integrity.

To configure sampling for the SDK:

Set logfire.configure() [trace_sample_rate ][logfire.configure(trace_sample_rate)] option to a number between 0 and 1, or
Set the LOGFIRE_TRACE_SAMPLE_RATE environment variable, or
Set trace_sample_rate profile options.

For more information, see Configuring.

import logfire

logfire.configure(trace_sample_rate=0.5)

with logfire.span("my_span"):  # This span will be sampled 50% of the time
    pass
