Drivers

Patterns whose cost grew the most vs. a prior period. Flags new patterns that didn't exist before.

Example

"today vs. yesterday — did the deploy move anything?"

Yes — 3 patterns account for 98% of yesterday's $9,646/wk increase:

1. Payment_Gateway_Timeout (NEW, ERROR) — $103 → $4,231/wk
2. Retry_Backoff_Exhausted (NEW, WARN) — $0 → $2,184/wk
3. GetCartAsync_called_with_userId (INFO) — $1,820 → $3,290/wk (+81%)

Want me to investigate Payment_Gateway_Timeout?

More to ask

• "biggest week-over-week increase"
• "this week vs. two weeks ago — skip the holiday week"
• "anything new in payments-svc since last deploy?"
