### [Your telemetry answers yesterday's questions](https://blog.olly.garden/your-telemetry-answers-yesterday-s-questions?utm_source=hashnode&utm_medium=feed)

Every piece of telemetry exists to answer a question. A span answers "what happened during this request?" A metric answers "how is this system performing over time?" A log answers "what did the applic

### [Reducing Log Volume with the OpenTelemetry Log Deduplication Processor](https://blog.olly.garden/reducing-log-volume-with-the-opentelemetry-log-deduplication-processor?utm_source=hashnode&utm_medium=feed)

Your logs are probably at least 80% repetitive noise. Connection retries, health checks, heartbeat messages: the same log line repeated thousands of times per minute. You pay storage costs for each one while the signal drowns in noise. The OpenTeleme...
