Highlights Logging at Twitter: Updated Centralized logging at Twitter was limited by low ingestion capacity and query capabilities which resulted in poor adoption. The previous solution ingested around 600K events per second per data center. However, only around 10% of the logs were submitted, with the remaining 90% discarded by the rate limiter. To address this, Twitter adopted Splunk Enterprise and migrated centralized logging to it. Now it ingests 4 times more logging data and has a better query engine and better user adoption.
