Remediate Fast

• Things you can’t easily diagnose with debugging tools– New Environment / Component - Pipe Cleaning– Race Conditions– Intermittent Faults– Performance issues– You don’t have a debugger active in that environment anyway plus

you would need multiple instances

• The stuff you wish you’d logged.


Pipe Cleaning – My bit works


Remediate Fast – Pure Path

The Pure Path stack trace can span components, servers and technologies

And may be viewed in different ways e.g. transaction flow above or as a sequence diagram those are the views I have used most - there are more.


Retroactive Logging – capture of parameters


Race Conditions - Threading


Race Conditions – Non Atomic Behaviour


Race Conditions – Resource Contention


Solution To Resource Contention


It’s the closest we get to debugging in Production
