One of our customers often has a "high transaction" week (200%-300%), and they warn us about it before it starts. There have been various load issues in the past (not even during these high transaction weeks). A couple of weeks before I figured out an issue which could lead to erratic behavior and addressed it. Various monitors became quite stable. When the high transaction week started, our monitoring showed absolutely nothing of significance. System load, memory usage, etc. everything was still pretty much a flat line. The people on stand-by were worried something was broken and the transactions weren't going through. But nope, everything was working perfectly. This was quite a while ago. In the mean time average number of transactions per day have increase, and peak transactions have become higher. But none of this is really visible in our system monitoring.
