Callaghan's cost-control advice: audit what's being logged. At BiggerPockets a three-day audit reduced the logging bill by 41%. Grouping by content key (or using a vendor feature that shows message patterns) surfaces outliers — he found the string 'okay' was being logged ~231 million times per month. Filter noisy logs via semantic_logger's proc filter, or exclude them at the collector. Pair with adding only what's needed for concrete questions to avoid cost sprawl.
