HoneyByte: Get a Taste for Sampling
Blog post from Honeycomb
Honeycomb's event-based pricing model focuses on the number of events sent, raising the question of how to maintain data quality while reducing event volume. Sampling is a technique to achieve this, allowing users to selectively transmit data without significantly compromising fidelity. Honeycomb supports the use of custom sampling logic, which can be implemented via the Ruby Beeline by overriding the config.sample_hook to filter less valuable or noisy events, such as redundant Redis or SQL commands, using a deterministic sampler. This enables trace-aware sampling by ensuring consistent decisions for all spans within a trace. However, users must be cautious to avoid common pitfalls, such as dropping spans with children or incorrectly implementing head-based and tail-based sampling, which can lead to incomplete trace waterfalls. The platform's configurability allows users to test and refine their sampling strategies, ensuring that only the most relevant data is transmitted while maintaining an accurate representation of their overall dataset.
