Hi,
I work on a global trading system which supports many users. Each user can book,amend,edit,delete trades. The system is regulated by a central deal capture service. The deal capture service informs all the user of any updates that occur.
The problem comes when we have crashes, as the production environment is impossible to re-create on a test system, I have to rely on crash dumps and log files.
However this doesn't tell me what the user has been doing.
I'd like a system that would (at the time of crashing) dump out a history of what the user has been doing. Anything that I add has to go into the live environment so it can't impact performance too much.
Ideas wise I was thinking of a MACRO at the top of each function which acted like a stack trace (only I could supply additional user information, like trade id's, user dialog choices, etc ..) The system would record stack traces (on a per thread basis) and keep a history in a cyclic buffer (varying in size, depending on how much history you wanted to capture). Then on crash, I could dump this history stack.
I'd really like to hear if anyone has a better solution, or if anyone knows of an existing framework?
Thanks
Rich
