You are welcome.

Ah, financial transactions. In that case it seems to me that you have two separate requirements:
1. Logging of requests, responses, errors. So the usual stuff to monitor the application
2. An audit trail of each financial event. In my opinion this does not belong in a logfile but in a database.
So in a single database transaction: create the bet, lock the customer account, debit the customer account and create an audit entry. If the transaction succeeds happy days, if it fails try to create a failure audit entry and report back to the customer. If all fails (a Ruby exception) then hopefully the logfile will at least record the error.

1) There is the possibility that the missing information could be crucial. Clients are settling bets based on these processes. If things go tits up on a major event (think Football World Cup and the like) a lot of money could be at stake and if it is not our problem but we cannot prove it then we could take a financial and reputational hit. Besides not knowing what happened when it went wrong makes fixing it hard

2) We used to use the rotation feature that was built into the Logger package but we found in the past that when summer time happened the logger died because the new file already existed (not sure what was happening but moving the logfile with that days timestamp elsewhere fixed it). It was in our support calendar to check for this specifically until we had migrated everything to use the standard logrotate. This was years ago and this may be fixed now but testing it is not convenient when summer time changes happen only twice a year :)

3) syslog does look like the next thing to look at. I had a feeling that the most reliable alternative would be this. I will have to dig into it further

I have considered logging to a queue and have a reader create the actual log file but syslog will probably be the simpler solution

Thanks for you input
