LangChain - Production DeploymentTo alert when a LangChain app's average latency exceeds 2 seconds over 10 minutes, which method is best?AManually check logs daily for latency spikesBAlert immediately when any single request exceeds 2 secondsCSet an alert for max latency > 2 seconds without time windowDUse a rolling average metric with a 10-minute window and alert if > 2sCheck Answer
Step-by-Step SolutionSolution:Step 1: Understand requirementAlert if average latency exceeds 2 seconds over 10 minutes.Step 2: Evaluate optionsRolling average over 10 minutes matches requirement best.Step 3: Eliminate othersImmediate alerts on single requests or max latency ignore averaging; manual checks are inefficient.Final Answer:Use a rolling average metric with a 10-minute window and alert if > 2s -> Option DQuick Check:Does Use a rolling average metric with a 10-minute window and alert if > 2s match averaging over time? Yes [OK]Quick Trick: Use rolling averages for time-based latency alerts [OK]Common Mistakes:MISTAKESAlerting on single slow requests instead of averageIgnoring time window in alert conditionsRelying on manual log checks
