• We are finding that performance and availability problems have increased with more frequent releases. That means Ops is spending more time troubleshooting, and development is being drawn into production troubleshooting.
• In response developers typically willsshinto a server or cloud environment, drop down to the command line.
• When the problem isn’t readily seen they begin grepping the logs usingregular expressions and hunt for patterns and clues to the problem. But grep doesn’t scale.Simply put, log data is everywhere. Application, system and network logs are stored indifferentlocations of each server, and may bedistributed across locations in the cloud or otherservers. Sifting through terabytes of data can take days.
